Re: [xmljs-users] Whitespace stripped before/after entities.

[David J. <dj...@ya...>]

Hi Stepan,

I *think* I might have a fix for this. I'll give it more of a look tomorrow and if it does work,
send you a new copy of xmlw3cdom.js.

What *are* you doing to my poor parser anyway?

:)

[xmljs-users] Whitespace stripped before/after entities.

[Stepan R. <xm...@no...>]

The W3CDOM parser incorrectly strips whitespace before and after entities.  For
example, the tag
    <TAG>Say Hello &lt;b&gt;World&lt;/b&gt; and Sky</TAG>
should be parsed as
    "Say Hello <b>World</b> and Sky"
but is incorrectly parsed as
    "Say Hello<b>World</b>and Sky"

A workaround (for my application) is to use
   parser.preserveWhiteSpace = true;
and then trim the text nodes myself.

The problem is caused in DOMImplementation__parseLoop() where you trim pContent
in XMLP._TEXT nodes.  The trimming should really only happen after text nodes
have been normalized (and thus contain entities).

The following demonstrates the problem:

function xmljsDOMExample() {
var xml;
xml = ""
+ "<?xml version=\"1.0\"?>"
+ "<ROOT>"
+ "<TAG1>"
+ "Say Hello &lt;b&gt;World&lt;/b&gt; and Sky"
+ "</TAG1>"
+ "</ROOT>";

//instantiate the W3C DOM Parser
var parser = new DOMImplementation();

parser.preserveWhiteSpace = true;

//load the XML into the parser and get the DOMDocument
var domDoc = parser.loadXML(xml);

//get the root node
var docRoot = domDoc.getDocumentElement();

//get the "TAG1" element
var tag1 = docRoot.getElementsByTagName("TAG1").item(0);

//the following should be
//"Hello <b>World</b> and Sky"
alert(tag1.firstChild.data);
}// end function xmljsDOMExample

Re: [xmljs-users] DOMNode.removeChild() doesn't cleanup pointers

[David J. <dj...@ya...>]

Hi Stepan!

Thanks for the bug report. I'll get this fix into 3.1. 

Would it be possible for you to provide a quick recreation for me on this bug. I'd like to take it
and put it into one of the test suites so we make sure this doesn't happen again...

Thanks!

[xmljs-users] DOMNode.removeChild() doesn't cleanup pointers

[Stepan R. <xm...@no...>]

The DOMNode.removeChild(oldChild) method does not clean up nextSibling and
previousSibling pointers of the oldChild. This can lead to problems when the
child is then appended to some other node.

The fix is in DOMNode.prototype.removeChild. Replace

  return oldChild;

with 

  oldChild.previousSibling = null;
  oldChild.nextSibling = null;
  return oldChild;

Re: [xmljs-users] Encoding/Unencoding issues

[David J. <dj...@ya...>]

Hi Robert,

Couple of questions...

1) Are you talking about the __escapeString and __unescapeString functions in the SAX file? Those
use regular expressions and as far as I can see are one pass. The classic dom is multi-pass
primarily because you can't count on regular expression support in all the browsers the classic
dom is supposed to work with.

2) 
>       1) original: "put an < in the sentence"

>       3) unencode(&): "put an < in the sentence"
>            unencode(&lt;): put an < in the sentence

That would be the behavior I would expect if (assuming the SAX/W3CDOM parser is used)
encode == __escapeString 
and 
unencode == __unescapeString 

I'm missing something I'm sure. Can you give a code example that'll help me?

That would totally rock. I thought &apos; was actually XML specific though and not an actual HTML
entity. Moz and Konq support it in HTML, but IE doesn't IIRC. I remember this due to a vague
memory of once saying "wow, something that IE is more compliant to the spec in than Mozilla. Wow!
A flying pig!" :)

> Thanks.

Again, this would totally rock. No one is working on this that I know of and I agree the escaping
is due for a redesign. If you would like to do this, I would really appreciate it and I will
happily include it in version 3.2 (or 3.1 if you're really quick). I would suggest the following:

* Unless you *really* want to go back and test with old browsers, I would leave the classic DOM
code as it is now.

* Put your new code in xmlEscape.js and just point all of the DOM and SAX escape functions to this
code. This will require that people include xmlEscape.js when using the W3C Parser and the SAX
parser, but I'm OK with this since your code will provide significant functionality - even outside
of XML for <SCRIPT>

* If you would like to turn the existing functions in xmlEscape.js into single pass (presumably
using regular expressions) that would be nice as well. If you do, I'll probably take the existing
file and call it xmlEscape4xBrowsers.js just so folks who have to support older browsers can keep
using the two functions is already provides without worrying about incompatibilities.

* A test suite and some documentation about what entities we will officially support would be very
nice!

Thanks again! 

David

[xmljs-users] Encoding/Unencoding issues

[<Rob...@Hy...>]

A few items:

- More immediate is that all of the unescape code (there are several in the
SAX and DOM files) should move the ampersand replacement after <, >,
" and ' to avoid:
      1) original: "put an < in the sentence"
      2) encode(&): "put an < in the sentence"
      3) unencode(&): "put an < in the sentence"
           unencode(&lt;): put an < in the sentence

- Moving forward the escape/unescape code should be reworked so that it is
converted in a single pass, as multiple passes can cause invalid
conversion.  Also, code needs to be added to handle &#hex; and &numeric;
syntax.  There are a host of other entities to be recognized, but they may
be HTML specific (like &apos;).

If someone is working on this or has some could that was started please let
me know, otherwise I will try to write it and submit it to the project.
Thanks.

[xmljs-users] Announcing XML for <SCRIPT> 3.1 Beta

[David J. <dj...@ya...>]

Hello all,

XML for <SCRIPT> 3.1 should be released by the end of March. The primary changes from 3.0 are a
few fixes to the W3C DOM Parser relating to empty nodes and importNode problems and the addition
of an XPath contributed add on. The XPath contributed add on allows for a subset of XPath
expressions to be executed against W3C DOM objects.

If anyone is interested in giving 3.1 a spin before it's released, I'd be happy to provide a
pre-release copy. I'd be especially interested in folks who want to try out the XPath
functionality to let me know how well it works in the "real world". If you are interested, please
drop me a private email at djoham(at)yahoo[dot]com.

Best regards,

David

Hi Robert!

I'm getting ready to put version 3.1 together (which by the way will fix the first bug you
reported - I need to think about the possible ramifications of the second) and if you would like
to do this, I would be happy to hold the release for a bit until you're finished. My only
requirement would be that the files be in UNIX line-termination format. I don't think they all are
now (Jon uses Windows) but I would prefer that we pick and stick to a standard.

What do you think?

David

Since most of use tab stops in our editors, changing the spaces to tabs
would increase the indenting (and legibility), as well as reduce the size
of the non-compressed files.  The files varied by author, some tabs were
floating around, some indented 2 spaces per level, some 4.

[xmljs-users] 2 bugs in empty tag handling with DOM

[<Rob...@Hy...>]

1) EMPTY ELEMENTS NOT ADDED - In DOMImplementation::_parseLoop, in the
"else if(iEvt == XMLP._ELM_EMP)" block, the call to
"iNodeParent.appendChild(iNode);" is only done in the "if
(!this.namespaceAware)" block.  If pushed this single line after the entire
if-then-else.

2) EMPTY ELEMENT SERIALIZATION INVALID - the last few lines of
DOMElement.toString should be like this:
  ret += "<" + this.nodeName + ns + attrs;
  if (this.childNodes.length > 0)
  {
    ret += ">";
    ret += this.childNodes.toString();

Re: [xmljs-users] How to load an XML file with xml for script?

[David J. <dj...@ya...>]

Hello!

There are a couple of different ways to do this in XML for <SCRIPT>. If you are only loading XML
data from your own domain, the easist way to do this is to use the xmlIOLoadLocalData method in
xmlIO.js. If you would like to load data from another domain (something I don't think MSXML lets
you do), you can also use one of the server-side proxies.

You can find documentation on this feature at the following address:
http://xmljs.sourceforge.net/website/documentation-tools.html#toolsIOLoadLocalData

You can find sample code that demonstrates this in action at the following address:
http://xmljs.sourceforge.net/website/tools-loadLocalXML.html


Hope this helps!

[xmljs-users] How to load an XML file with xml for script?

[Nermin B. <us...@gm...>]

I would like to load an XML file from web server and parse its values while
using xml for script. All examples I was able to found are limited to parsing
XML that is within html on the page locally.

Currently I am using “Microsoft.XMLDOM” for loading an separate XML file
into page:


xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = false;
while(xmlDoc.readyState != 4) {}; 
xmlDoc.load(“mydata.xml”);

var rootNode = xmlDoc.documentElement;

… (And than reading elements)

mydata.xml is an separate file stored locally.

How will this code look with XML for script??

Thank you in advance:

Re: [xmljs-users] parsing 1200 nodes

[David J. <dj...@ya...>]

Hi Chandan,

1200 nodes is pretty much the upper limit XML for <SCRIPT> can handle. At that point the
JavaScript interperator starts getting bogged down with all the objects it needs to create. A lot
of it depends on the speed of the computer as well (naturally).

If XML for <SCRIPT> is too slow, you might try sarissa at http://sarissa.sourceforge.net/. I've
never tried it myself, but it uses the native DOM implementation of IE and Mozilla so the speed
should be much faster. The price you'll pay is that you'll probably lose Safari, Konq and Opera
support. You also need to be aware that Sarissa is GPL (rather than LGPL) so if you want to use it
you need to be prepared to accept the more viral terms of its license. One option would be to use
Sarissa for IE and Mozilla and XML for <SCRIPT> for the other browsers. The other browers would be
slower, but at least functional after the initial load.

If you do try it and it works, please let me know and I'll add it to the FAQ.

Best regards,

David

Hi David,
I am using your wc3dom xml parser for parsing a xml string of around 1200
nodes....problem is it takes over 30 secs to load in internet explorer.

Is there any upper limit on the number of nodes it can parse fast enough? Do

[xmljs-users] RE: xmljs-users digest, Vol 1 #12 - 2 msgs

[James S. E. <jam...@co...>]

The way I avoid that kind of problem is to write empty nodes as if they
weren't empty:

<ZIPCODE id="12345"></ZIPCODE>

Just out of curiosity, why don't you use the ZIP code itself as the content
instead of as an attribute value?

<ZIPCODE>12345</ZIPCODE>

Subject: [xmljs-users] Empty Nodes

Hi

I tried to parse nodes whitout text-content with the w3cdom-parser, until
here
there is no problem. When I try to get these empty nodes (to get the
attributes) i can't access them, these nodes are not in the dom-tree.

example xml taken from the sample-section and modified:

<?xml version="1.0"?>
<CONTACTS>
     <CONTACT id="4" >
        <FIRSTNAME>
            Kelly
        </FIRSTNAME>
        <LASTNAME>
            VanMcIntyre

            AZ
        </STATE>
        <ZIPCODE id="12345" />

The Node "ZIPCODE" is not present in the dom-tree. Is there a way to get
these
Nodes?

Hi Thomas,

I think you're running into a known issue with the 3.0 parser. I have
attached a new version of
xmlw3cdom that should fix the problem for you. It's part of the 3.1 release
which should come out
sometime in late March or Early April.

Please let me know if this doesn't fix the problem for you...

David

Re: [xmljs-users] Empty Nodes

[David J. <dj...@ya...>]

Hi Thomas,

I think you're running into a known issue with the 3.0 parser. I have attached a new version of
xmlw3cdom that should fix the problem for you. It's part of the 3.1 release which should come out
sometime in late March or Early April.

Please let me know if this doesn't fix the problem for you...

David

[xmljs-users] Empty Nodes

[Thomas S. <tho...@gm...>]

Hi

I tried to parse nodes whitout text-content with the w3cdom-parser, until here 
there is no problem. When I try to get these empty nodes (to get the 
attributes) i can't access them, these nodes are not in the dom-tree.

example xml taken from the sample-section and modified:

<?xml version="1.0"?>
<CONTACTS>
     <CONTACT id="4" >
        <FIRSTNAME>
            Kelly
        </FIRSTNAME>
        <LASTNAME>
            VanMcIntyre
        </LASTNAME>
        <ADDRESS>
            92535 Highway 6
        </ADDRESS>
        <CITY>
            Somewhere
        </CITY>
        <STATE>
            AZ
        </STATE>
        <ZIPCODE id="12345" />
    </CONTACT>
</CONTACTS>

The Node "ZIPCODE" is not present in the dom-tree. Is there a way to get these 
Nodes?

Re: [xmljs-users] Xpath Searches

[David J. <dj...@ya...>]

Hi Chandan,

Currently, XPath isn't supported by the w3c parser. I'm working on a rather limited XPath solution
at the moment that I hope to release sometime in the April timeframe. It will be similar in
functionality to the tagPath searching for the classic DOM. 

Best regards,

David

[xmljs-users] Xpath Searches

[Chandan K. <cha...@bl...>]

Hi,

Can we do XPath searches in the W3C version of the XML Parser. 

I have the following XML - 

<root>
	<tagName1>
			<text>1</text>
			<tagName2>
					<text>1</text>
					<tagName3>
							<text>1</text>
					</tagName3>
			</tabName2>
	</tagName1>
</root>


I want to make an XPath expression search for //tagName1//tagName2//tagName3

Could you please suggest, how can I make the search if I have a w3cDOM
implementation.

Thanks and regards,
Chandan

Re: [xmljs-users] xmlUnescapeHTMLToXML problem in Mozilla 1.5 and 1.6

[David J. <dj...@ya...>]

<oops, forgot to cc the list. I'm doing so now and added another question>

Hi James,

No clue here. I just tried the Linux version of Mozilla 1.6 with the xmlIOLoadLocalData sample
application and it worked fine. Are you using Windows? If so, what happens when you go to 

http://xmljs.sourceforge.net/website/tools-loadLocalXML.html

and run the sample? Does it work? If so, can you see if there is any difference in what your php
is putting out vs. the text file? Is your php script on the open internet somewhere where I can
take a look at it?

David

      My PHP server application escapes XML as follows:

      $xml = "<?xml version=\"1.0\" ?>"
               . " <personal-agent
member=\"".$this->member->get_handle()."\"
messages=\"".$this->new_messages."\" alerts=\"".$this->alerts."\"
posts=\"".$this->new_posts."\"
events=\"".$this->events."\"></personal-agent>";
      $xml = str_replace('<',chr(171),$xml);
      $xml = str_replace('>',chr(187),$xml);
      $xml = str_replace('&',chr(167),$xml);

      In Internet Explorer 6, xmlUnescapeHTMLToXML correctly unescapes this
as follows (for example):

      <?xml version="1.0" ?>
      <personal-agent member="member_name" messages="1" alerts="0" posts="5"
events="0"></personal-agent>

      In Mozilla, however, xmlUnescapeHTMLToXML returns this:

      <?xml version="1.0" ?<
      <personal-agent member="member_name" messages="1" alerts="0" posts="5"
events="0"<</personal-agent<

      In other words, it unescapes both greater-than and less-than symbols
as less-than sysmbols. Any ideas what might be causing this?

      Thanks,

Re: [xmljs-users] Performance problem

[David J. <dj...@ya...>]

Hello,

7000 lines? That might be a little bit more than XML for <SCRIPT> can handle, unless you're on a
very fast computer. XML for <SCRIPT>  is dependant on the speed of JavaScript on each browser.
Sadly, JavaScript isn't the fastest thing around and as you get more and more nodes, XML for
<SCRIPT>'s performance starts to drag.

Sadly, there isn't a whole lot I've been able to figure out to do about this. The Classic DOM is
faster than the W3C DOM, but not a whole lot faster. My current idea is to try to somehow use the
C++ based parsers of the individual browsers, but that solution is still unproven.

I'm sorry if XML for <SCRIPT> won't work for you, but I'd rather tell you how it is than try to
lead you down a path I don't think will work for you...

Best regards,

David
