phpxpath-users — General user discussion of Php.XPath

The CDATA problem

[zhang l. <ob...@gm...>]

In version 3.5 .The xml parser will remove all CDATA tag ,and can not be
restored.For example,import from a  xml file,and then export to a new file
,the new file will lost all CDATA tag.
how to keep these tags while parsing?

If you are in a hurry, then you are better to post to phpxpath-users, as =
that way it won't be just me who sees your questions.

The short answer is that you'll have to deal with it yourself. =20

For the long answer, search in the code for these symbols to see a full =
description of the problems:
- parsInCData
- xml_set_default_handler
- xml_set_character_data_handler
- _translateAmpersand

CData caused parsing problems, and as such it's structure is not stored, =
rather it is treated as part of the containing textnode.  You might be =
able to "formally" remove the <!CDATA[ ]]> parts passing the string you =
get back from wholeText() through the xml parser, but you'd have to wrap =
it in <> stuff in order to make your string a valid xml document.

Returns a list of features:
//feature[contains(.,'search string')]

Returns a list of components
//feature[contains(.,'search string')]/..

The trailing /.. is no accident.  It filters duplicates too

Re: XPath Search

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

I've narrowed the problem down.  When I search through keywords in the =
xml file (each component has one keyword tag with multiple words) it =
works fine using:
$components=3D$xPath->match("//component[contains(keyword,'string')]");
but when I search through features (each component has multiple =
features) using:
$components=3D$xPath->match("//component[contains(feature,'string')]");
I get an empty array.

Do I have to do something different if there are multiple tags such as =
feature?

Worked it out.  When you search for =
//component[contains(feature,'string')], then it first of all evaluates =
//component to get a list of context nodes, which will be something =
like:

XPathSet:Array
(
    [0] =3D> /product[1]/component[1]
    [1] =3D> /product[1]/component[6]
)


Then it filters the list based on the predicate, which is the =
contains(feature,'string') bit.  But to do this, it needs to evaluate =
the "feature" for each of the context nodes.  But for the first context =
node this returns something like:

Array
(
    [0] =3D> /product[1]/component[1]/feature[1]
    [1] =3D> /product[1]/component[1]/feature[2]
    [2] =3D> /product[1]/component[1]/feature[3]
    [3] =3D> /product[1]/component[1]/feature[4]
)


So the LHS is an array, and the RHS is a string.  According to =
http://www.w3.org/TR/xpath#function-string, the contains function will =
convert the LHS to a string by "A node-set is converted to a string by =
returning the string-value of the node in the node-set that is first in =
document order. If the node-set is empty, an empty string is returned.". =
 And thus it will take the text part of =
/product[1]/component[1]/feature[1], and ignore the rest.

This explains why it works for the keyword, as you only have one =
keyword.

Instead of finding all components, and then filtering the list, instead =
we should find all features, and then go back up a level to get their =
owning components.  So we do:

//feature[contains(.,'search string')]/..

Re: XPath Search

[Tod M. <tod...@gm...>]

Can someone help me out?  I can't seem to get the match working...

I'm using:
$components=3D$xPath->match("//component[contains(feature,'string')]");
which returns nothing in the array, even though "string" is in the file

when I use : $components=3D$xPath->match("//*[contains(.,'string')]");
however, it works.

This isn't exactly ideal though as I just want to return the component node
itself that contains the "string" within the feature, not the actual
feature.

Nigel, your solution of
$components=3D$xPath->match("//*[contains(feature,'string')]"); doesn't wor=
k
either.  It seems whenever I put the actual node name in the contains
function it doesn't work.

  I have a couple of question that i would thank you if you can answer =
them as soon as possible:
  - If I would like to take only the nodes that apply to the XPath =
Expression directly, what i have to call or use?
You'd call match() which will (probably) return you a set of nodes.
  - What if the XML has sintax errors?
importFromFile() or importFromString() will fail.  Why don't you try it =
out and you'll see what happens.
  - Is there any script recommended to validate or tidy a XHTML string =
without using PHP extensions?

  Best regards,
Probably.  But don't have any relevant advice to offer.  Sorry!

Re: quick question Php.Xpath

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

You've found a bug, thanks!  So now you have two choices:

1) Get the latest version (153) from cvs which has a fix for the issue
2) Use setAttribute() instead

Cheers

[ANN]: VTD-XML 1.0 released

[Jimmy z. <cra...@co...>]

I am pleased to announce that both Java and C version 1.0 of
VTD-XML -- an open-source, high-performance and non-extractive
XML processing API -- is freely available on sourceforge.net.
For source code, documentation, detailed description of API
and code examples, please visit

  http://vtd-xml.sourceforge.net

New in VTD-XML 1.0 is the integrated support of XPath that also
features a easy-to-use interface that further enhances VTD-XML's
inherent benefits, such as CPU/memory efficiency, random access,
and incremental update. A demo of the XPath capability is available
at

  http://vtd-xml.sourceforge.net/demo.html

For further reading, please refer to the following articles about
VTD-XML

  Subject: xpath getNode problem


  Hi Nigel
  Firstly I should thank you for php.xpath. Without it I don't think I could
have done what I was trying to do.
  But there's one thing I can't quite work out -
  I have a structure like this to store notes hierarchically:

  <NOTES>
  <NOTE id="1"><HEAD>heading 1</HEAD><KIDS></KIDS></NOTE>
  <NOTE id="2"><HEAD>heading 2</HEAD><KIDS>
      <NOTE id="3"><HEAD>heading 3</HEAD><KIDS></KIDS></NOTE>
      </KIDS></NOTE>
  <NOTE id="4"><HEAD>heading 4</HEAD><KIDS></KIDS></NOTE>
  </NOTES>

  and what I'd like to do is move 'NOTE 2', along with the contents of it's
KIDS (ie 'NOTE 3') to the KIDS scope of 'NOTE 1'

  I'm assuming I'd have to store 'NOTE 2' as a variable, then delete it from
the document, then re-insert it in the new place, but I'm having problems
storing it in a variable.
  I've tried various combinations of getNode, eg:
  $note[] = $x->getNode('/NOTES[1]/NOTE[2]');
  but I must be missing something as print_r($note); is always empty

  how would you suggest I go about this?

  thankyou very much for your time
  Suzanne

CDATA - how to remove?

[Robert W. <rob...@gm...>]

hi,
i have to update a very old phpxpath version. now some problems occured.

when using getData(), every text node containing CDATA is returned
with the CDATA statement in it.

the CHANGES file says:
>Version 2.2 - 2nd February 2002
>CData support started  You can now losslessly import and >export
CDATA in and out of the class.

is there a function that removes the CDATA stuff? if not, i think it's
quite annoying, that everybody had to write his own function to do
that.

cheers,
  robert

PHP.XPath getAttribute() missing

[Andrej A. <aa...@ap...>]

hello nigel, everyone

there are setAttribute(), setAttributes() and getAttributes().
there are references to getAttribute(). but the method itself is missing.
i've checked the newest 3.5 version (working with 3.3)

add it or remove the references?

PHP5 problems...

[<tw...@ks...>]

Hi

I have a few problems with my script when running it on a server with PHP=
5.

First -- encoding. Somehow the initial processing instruction=20
disappears. I have a header: <?xml version=3D'1.0' encoding=3D'iso-8859-1=
'?>=20
when I run the exportAsXml method, the header is the default <?xml=20
version=3D'1.0'?>. This is not a big issue, since I can just specify the=20
correct header to use when exporting.

Second -- CDATA-tags disappear. In 4.x I have to manually strip the=20
enclosing <![CDATA[ ... ]]> marks on my text. Apparently that is no=20
longer necessary in 5.0. Nice, but when I export my xml-document the=20
CDATA tags are also missing. This results in the parser breaking down=20
when I try to read in the xml document after exporting it.

Has anyone experienced the same and found a usable workaround for the=20
CDATA issue?

Best regards,
Torben W=F6lm

redesign your system?  ;-) 

I've not tried using phpxpath with such a large file but because it reads the 
whole document in every time not only will it require lots of memory it's 
likely to be very slow too. And because php is stateless it has to do it for 
each request. Depending on the number of users your memory usage and response 
times could be enormous. It all sounds hugely inefficient to me. 

I would be thinking in terms of splitting the data up, perhaps storing it in 
an rdbms and using phpxpath as a front end.

XPath large file problem

[ac s. <ac_...@ho...>]

hi,

I am having trouble parsing a large file as it is in excess of 12Mb. If i 
use a small file like 500Kb then it works fine but if i use a large file the 
script dies saying memory limit exceeded.

I have also tried to increase this limit to 32Mb but the result is the same.

Any ideas how i can go about doing this.

Thanks and regards

[phpxpath - Help] memory pb using ImportFromString

[SourceForge.net <no...@so...>]

Read and respond to this message at: 
https://sourceforge.net/forum/message.php?msg_id=2761638
By: xlhostis

 
I have à memory pb using ImportFromString using with 
xml syntax like this :

<ENVELOPPE>
<UC>UBGDS_ANIMAL_DEC_GAR_BVD</UC>
<CODORG>G350</CODORG>
<IDEEVT>20040906122713</IDEEVT>

<CAUGAR>VNG</CAUGAR>
</GARANTIE>
</ENVELOPPE>


The memory is not liberated after each ImportFromString

so with 10000 <ENVELOPPE> the memory allowed to php 
is exhausted.

Any idea ?

bug/question regarding _translateAmpersand();

[Spencer R. <oob...@ya...>]

Hi everyone.

First I'd like to say that PHP.XPath has made my life
a hell of a lot easier.  Thanks!

Second, I'd like to mention what I think is a bug. 
I'm using v3.5 and it chokes on &copy, &gt, and &lt
(maybe more, but those are what I've used).  I've
traced through the _translateAmpersand() function in
the .class file, and I don't see why it doesn't work. 
When I use any of those entities normally, Firefox
tells me it's an empty document and won't load.  When
I manually make the corrections (ie. "©") in
my sources, the output source from PHP.XPath generates
"&©", and it displays the desired character
preceded by an & in the browser view.

Am I using it wrong?  is this a bug?
Here's my config (Apache/2.0.50 (Win32) PHP/5.0.0)

Thanks,
oobleck

P.S. Ok, I see it now.  I'm using PHP5, but it seems
not to work at all in PHP5.  How can I circumvent this
problem?  Any ideas?
