[phpXML] Re: [phpXML] beginners question

[<nig...@us...>]

Phpxml was written on a system that didn't care if an array index wasn't =
set yet.  The windows PHP engine isn't one of these so you need loads of =
if (!isset(arrayentry)) {arrayentry =3D ""} bits throughout your code.

I've attached Tim Strehle's patch for this bug.  I haven't tried it =
myself, but it was the first one that came to hand.

Contrary to the other posting by yf32, I would recommend you use =
require_once() as xml.php doesn't change, and contains only definitions.

Did you try

$BasePrice  =3D $xml->get_content($Product."/Pricing[1]/BasePrice[1]");

?

All paths to get_content must be complete.  You seem to have missed the =
[1] in the pricing argument.

[phpXML] Re: [phpXML] Problems using element[@attribute=''] syntax ??

[<nig...@us...>]

Have you tried:

$aArray =3D  =
$calendarXML->evalute("/calendar[1]/month[normalize-space(@number)=3D'01'=
]/day[normalize-space(@number)=3D'02']","entry");
// ...You should really check that $aArray has exactly 1 element, =
then....
$newNode =3D $calendarXML->add_node($aArray[0],"entry");
$calendarXML->add_content($newNode,"something");

Undoubtedly addnode will require an ABSOLUTE address of the node to =
which you would like to add a node to.  If you pass evalute the string =
of the search that you think will produce you 1 node, then evaluate will =
return you an array of absolute addresses.  You can then pick the first =
address and add a node there.

get_content, set_content, get_attributes, set_attributes, add_node, =
delete_node ALL require ABSOLUTE FULLY QUALIFIED ADDRESSES.  ie =
/a[1]/b[2]/c[3]

If you want to use fancy XPath you have to use evalute() to obtain the =
absolute address then pass that back into the other "lower level" =
functions.

There have been loads of postings along these lines so far, and a lot of =
people on this list who still haven't quite got this point yet (It took =
me a while too...).  If you are ever having difficulty, then call =
evalute() and print_r() the results.  This will tell you if you XPath is =
wrong.  The documentation that declares that functions like add_node or =
get_content take XPath expressions is somewhat misleading in that you =
can't pass in any old XPath expression.  You must pass in a subset of =
XPath mainly those XPath expressions that are fully qualified.

[phpXML] Re: [phpXML] miss-match

[<nig...@us...>]

I looked into this the other day and I think it will require a fairly =
major rewrite of some of the code.  Currently the internal structure =
only has one text parameter per node, so when it reads "Text" it adds it =
to the text node of blah1, then when it reads "text" then it appends it =
to the text node to get "Text text".  Hence when you write it back out =
the internal structure has lost the descriptive ability to Put "Text" =
before <blah2> and "text" after </blah2>.

In order for phpXML to support this kind of behaviour, the internal =
data-structure needs to be able to associate a text block that comes =
after a element.  You could then assoicate "text" as the after element =
text of the <blah2> tag.

So in this example <blah> has text data of "Text", and <blah2> has text =
data of "more" and a post-element-text-data of "text".  Clearly the root =
element is not allowed to have any post-element-text-data as I think =
this would be invalid XML.=20

At least that's how I thought I'd do it...  Fortunately I don't need =
this feature for my application.  So unless I get really bored I won't =
be implementing this :o)

Try calling print_r() on the object after you have given it an xml file =
and you'll quickly see the internal structure.

Incidentally, I've written a get_file_as_xml() function that dumps the =
object in a format suitable for writing straight to file.  When I've =
finished testing I'll pass it on to you all.

I'm not sure that this actually solves the stated problem though as I =
think I am right in saying that this is a fix that goes into get_file(). =
 Therefore if the datastructure can't describe =
"Before<tag>Middle</tag>End", then it's not going to be able to print =
it.

This fix will cope with usage of the object that make calls to =
set_content("address","Some text <B>that</B> contains some markup.").  =
But if the xml file that you read in already has "Some text <B>that</B> =
contains some markup." then the class is going to loose this structure =
in the parse.

Basically phpxml's internal datastructure is lossy.  You can't read to =
object and write back out to file and have two logically identical =
files.  Ideally it ought to be.

We need a more complete fix for this in the constructor or =
load_from_file function I think....

I'm pretty sure it is a well-formed XML structure.  I'll research =

It couldn't possibly be the output from phpXML.  As I have already =
argued, the phpXML class is unable to represent such a structure =
internally, so it can't output text of this form.

Many XML documents never use a mix of text and elements below a node, =
hence you never see this issue.

> the replace and delete node.

I'm intrigued how you manage this.  When I ask phpXML to get_file.  It =
escapes all the <> with &lt; &gt; and I get:

&lt;blah1&gt;
  Text&lt;blah2&gt;more&lt;/blah2&gt;text.
&lt;/blah&gt;

This is not a well-formed XML document as it is both missing a <?xml =
.... ?> bit (easily added) but it more annoyingly doesn't have a root =
node, as the root node has been escaped by &lt and &gt so the blah1 =
element is no longer an element but is now text.

[phpXML] Re: [phpXML] phpxml as XLST transformer?

[<nig...@us...>]

> Is it possible...? I am looking for the easiest way to preform simple xml
> xslt html transformations

I think trying to do XSLT with phpxml would be a bit of a nightmare.  It
would only really work for very specific and simple cases, so if you are
happy with that then fire away.  You are going to have to write a fair
amount of PHP for each page in order to process an xml file with elements in
an unpredictable order.

I don't know what the phpxml users out there use it for, but I see it more
as a method of making alterations to an existing xml document, and making
and displaying XPath queries of an xml document.  XSLT works by reading
through the xml document from start to finish and processing the elements as
it goes.  Phpxml reads the whole xml document into an object that can then
be queried.  Trying to get an XSLT approach from phpxml is therefore clearly
going to be difficult.

I think that it would be easier to write a watered down XSLT processor from
the basic XML parser functions, that phpxml is built upon, than to write one
on top of phpxml.  There might be some other php projects out there that
might help, but I don't know of any to suggest.

Presumably you don't have the "sablot" PHP XSLT library available to you?

[phpXML] Re: [phpXML] Need example for 'context'

Try using a context of /government[1]

The context (I think) has to be a COMPLETE address.  Not just an XPath =

I haven't tested this, but I think this is right.

[phpXML] phpxml Version 1.N.3

[<nig...@us...>]

If anyone is interested, you'll find a release of phpxml at
http://sourceforge.net/projects/phpxmldb/ with most of the bugs and
enhancements that have been requested in the 125 messages that have been
posted here in the 3 weeks that this list has been alive.

Release notes also avaliable containing a list of the changes since phpxml
1.0.

http://sourceforge.net/project/shownotes.php?group_id=31522&release_id=44340

Sorry folks,  I still haven't got my hands of a copy of this DIFF program
that people keep talking about, otherwise I'd have include a DIFF too.  Some
25% of the file differs from the original now, so a DIFF would probably be
quite heavy going...

I'd post this at the phpxml project at sourceforge, but I'm not a developer
there as yet.  The phpxmldb work relies on phpxml so it's not a completely
stupid place to post it :o)  As such ftp://129.215.200.115 will no longer be
serving phpxml version 1.N.X

Some of you might be interested in the phpxmldb work, you might want to take
a look, but please don't innondate me with mails about it as it's only a wee
pre-alpha baby, however comments about the direction of the project would be
appreciated.  :o)

Best regards

Nigel

The class doesn't support this.  More accurately the evaluate() function =
doesn't support this.  You'll have to break into the $object->nodes =
array to get this information if you are not happy with using string =
processing on the XPath addresses.

I'm afraid this isn't an XPath question.  There is no magic XPath =
expression that will do this for you.

Try calling print_r($Object) and you will learn about the internal =
structure of the class, and which array to examine.  I would advise that =
you do not use "back doors" into the class however, and that you use =
string routines to obtain the array that you desire from running =
evalutate('/publication/*').  Luckily/Unluckily PHP doesn't really =
support the concept of 'private' class data.

You seem to be looking for Sub not Subs in test.php.  From my experiences
phpxml is case sensitive to content, so it is probably case sensitive with
element names too.  It's easy enough to test.

A friend of mine did some investigation and could find no evidence of
cas-insensitive matching in the XPath spec.  A weakness that we will have to
address.  I've not researched this myself yet though.

This project is suffering from lack of mail list archive, and list of =
known bugs.  I'm trying to provide that by the 1.N.X releases and the =
change log.  The 1.N.X releases contain what I believe to be all of the =
bug fixes and extra functions that have been mailed to this list to =
date.

If there is a strong feeling from the members of this list that I should =
not discuss 1.N.X releases on this list, then let me know and I'll stop =
posting them.  Given that there have been 20 or so downloads to date, I =
would presume this isn't the case?

Bug in mail list software.  This was covered last week in several =
postings.


Michael, could you post a list of "known bugs" or FAQs about this list.  =
We seem to be revisting the same ground over and over in the list.  =
Without an archive, there is no way we can have any grounds for =
complaining when someone descovers an already known about bug.

We are all busy people and we are going to saturate in re-answering old =
questions and not progressing the phpxml class, which is after-all why =
we are on the list!

I'm developing a kind of bug reporting system at =
www.carrubbers.org/scripts/explorerindex for a script that I am wanting =
to publish.  This is the project that I am using phpxml for.  When I've =
progressed that further you are welcome to a copy of the code if you =
like.

Better ideas anyone?

Nigel

[phpXML] phpxml Version 1.N.4

[<nig...@us...>]

Spotted a major blunder in 1.N.3.  Well only major if you are using
operators in your XPath searches.  They all end up getting evaluated as mod
as I missed the break statements from the switch block.  This means you
often get div/0 errors as false is interpreted as 0.

Oops. Sorry :o)

Also made what I think is quite an important optimisation to some of the
evaluate() private functions so that searches with fully qualified node
positions will take 3 less function calls than they were.

What version of phpxml are you using.  Check out version 1.N.X for the
latest version.  Version 1.N.X maintains much more whitespace than version
1.0.

http://sourceforge.net/projects/phpxmldb/

If that version is still causing hassles, please send an xml example with
the whitespace that is getting stripped and I'll see what I can do for a
future 1.N.X release.

[phpXML] Help with DTDs?

[<Adm...@ne...>]

 <<test.zip>> 
Hi all,

Included in the attached test.zip file are 3 files:

1. test.php - an example script for this question
2. xmlfile_faulty.xml - an xml file that does not work with test.php (ie. it
does not return the <sub> element as I intended
3. xmlfile_good.xml - an xml file that works correctly with test.php

The only difference between the two xml files is at the start of the DTD
(and the case of the elements)...
xmlfile_good.xml:
<!ELEMENT resp (response)>

xmlfile_faulty.xml:
<!ELEMENT CANCEL (RESPONSE)>

[BTW: is XPath case-sensitive? ie. should I change //SUB to //sub?]


Can anyone tell me how to change test.php to work with xmlfile_faulty.xml?? 

Regards,

Addam Breen

[phpXML] RE: [phpXML] Help with DTDs?

[<Adm...@ne...>]

ah... i thought i had tried with //SUB and //sub, but evidently not.

xml->evaluate() is INDEED case-sensitive!

Thanks Nigel,

Addam

You seem to be looking for Sub not Subs in test.php.  From my experiences
phpxml is case sensitive to content, so it is probably case sensitive with
element names too.  It's easy enough to test.

A friend of mine did some investigation and could find no evidence of
cas-insensitive matching in the XPath spec.  A weakness that we will have to
address.  I've not researched this myself yet though.

[phpXML] RE: [phpXML] miss-match

[<wl...@bl...>]

By Using <!CDATA[ any <tagged> text ]]
i've modified my xml.php version to detect weather there are html tags or
other text that might ruin an xml document structure.

modified xml.php included..

// From my previous email to the list
Here's a little snippit from the xml.php I modified to accomodate the lack
of CDATA creation in a node that contains characters that would otherwise
make an XML document invalid.  What do you think?  Can you improve it?

-When I call $xmlobj->get_file(); it will go through the $xmlobj->nodes
array and format the XML document.
-For every 'text' node it will scan for characters such as "<>&".
-If it encounters such characters it will add the <![CDATA[ tag before
and ]] tag after the 'text' node.
-Else just write out the 'text' node.


			if (strspn($this->nodes[$root]["text"], "<>&") > 0) {
				// Add the character data to the XML data with CDATA tags around it.
				$xml .= $before."  <![CDATA[\n";
				$xml .= $before."    ".$this->nodes[$root]["text"]."\n";
				$xml .= $before."  ]]>\n";
			} else {
				// Add the character data to the XML data.
				$xml .= $before."  ".$this->nodes[$root]["text"]."\n";
			}

Look for this comment in your xml.php under the get_file() function if you
want to know where i put it.  It's around  line 355
	// Add the character data to the XML data.

How can I get around phpXML's tendency to place tags inside regular text
after the tag containing the text.
 i.e.,
    <blah1>
            Text<blah2>more</blah2>text.
    </blah>
Comes out
