I've got this php snippet:



$xsltPath = $argv[1];

$xmlPath = $argv[2];



$xslt = file_get_contents($xsltPath);

$xml = file_get_contents($xmlPath);



$templateCMSObj = new DOMDocument();

$templateCMSObj->loadXML($xslt);

$ekbXMLObj = new DOMDocument();

$ekbXMLObj->loadXML($xml);

$proc = new XSLTProcessor();

$proc->importStylesheet($templateCMSObj);

$html = $proc->transformToXML($ekbXMLObj);

echo($html);

exit;


Which simply applies an XSLT to a given XML document.



When I apply the below XSLT to the same XML doc I got a different behaviour of Windows wrt to Linux PHP version.

Linux output
This is the desired output which actually results from applying XSLT on Linux:



<?xml version="1.0"?>

<ns:flat_pallet xmlns:ns="http://new.webservice.namespace" tipo="">

    <ns:riferimento_oi labelPath="Standard{0}/Standard{0}" unitIndex="1">

        <ns:tipo>Standard</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.1</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

    <ns:riferimento_oi labelPath="Standard{0}/Standard{1}" unitIndex="2">

        <ns:tipo>Standard</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.2</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

    <ns:riferimento_oi labelPath="Standard_due{0}/Standard{0}" unitIndex="1">

        <ns:tipo>Standard</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.1</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

    <ns:riferimento_oi labelPath="Standard_due{0}/Standard_due{0}" unitIndex="1">

        <ns:tipo>Standard_due</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.2</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

</ns:flat_pallet>


Windows output
This is the wrong result produces on Windows:



<?xml version="1.0"?>

<ns:flat_pallet xmlns:ns="http://new.webservice.namespace" tipo="">

    <ns:riferimento_oi labelPath="Standard{0}/Standard{0}" unitIndex="1">

        <ns:tipo>Standard</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.1</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

    <ns:riferimento_oi labelPath="Standard{0}/Standard{1}" unitIndex="2">

        <ns:tipo>Standard</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.2</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

    <ns:riferimento_oi labelPath="Standard_due{NaN}/Standard{0}" unitIndex="1">

        <ns:tipo>Standard</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.1</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

    <ns:riferimento_oi labelPath="Standard_due{NaN}/Standard_due{NaN}" unitIndex="">

        <ns:tipo>Standard_due</ns:tipo>

        <ns:natura_OI>

            <ns:UNI>2.2</ns:UNI>

        </ns:natura_OI>

    </ns:riferimento_oi>

</ns:flat_pallet>


The problem lies in the NaN put instead of relative index: it surely has to do with xsl:number element, but I can't figure out how to fix this...




Edit after accepted answer



By changing xsl:number count attribute to * instead of node() the xslt template works as expected on both Win and Linux.



Here's the updated code:

    This is very interesting! Issue can even be reproduced in xslt fiddle, toggling the engine between Saxon and others to "client-side processor".

    This would be much easier (and more useful to others) if the example were minimized to only what's necessary to show the problem - see: Minimal, Complete, and Verifiable example.

    At xsltfiddle.liberty-development.net/6qVRKxe/2 I have tried to make a reduced test case, with Chrome (at least my current version 70.0.3538.102 on Windows 10 64-bit) it shows the problem. @nwellnhof, is that a bug in the Windows version of libxslt? I am having a hard time to find an up to date binary of xsltproc/libxslt for Windows to test myself.

    For what it's worth, I tried the latest PHP release 7.2.12 on Windows which has the latest libxslt 1.1.32 and it exhibits the problem, so I have opened an issue on libxslt at gitlab.gnome.org/GNOME/libxslt/issues/6 to see whether they consider it a bug.

I've got this php snippet:

$xslt = file_get_contents($xsltPath);

$xml = file_get_contents($xmlPath);



$templateCMSObj = new DOMDocument();

$templateCMSObj->loadXML($xslt);

$ekbXMLObj = new DOMDocument();

$ekbXMLObj->loadXML($xml);

$proc = new XSLTProcessor();

$proc->importStylesheet($templateCMSObj);

$html = $proc->transformToXML($ekbXMLObj);

        </ns:natura_OI>

    </ns:riferimento_oi>

</ns:flat_pallet>


The problem lies in the NaN put instead of relative index: it surely has to do with xsl:number element, but I can't figure out how to fix this...




Edit after accepted answer



By changing xsl:number count attribute to * instead of node() the xslt template works as expected on both Win and Linux.



Here's the updated code:

    This is very interesting! Issue can even be reproduced in xslt fiddle, toggling the engine between Saxon and others to "client-side processor".

    This would be much easier (and more useful to others) if the example were minimized to only what's necessary to show the problem - see: Minimal, Complete, and Verifiable example.

    At xsltfiddle.liberty-development.net/6qVRKxe/2 I have tried to make a reduced test case, with Chrome (at least my current version 70.0.3538.102 on Windows 10 64-bit) it shows the problem. @nwellnhof, is that a bug in the Windows version of libxslt? I am having a hard time to find an up to date binary of xsltproc/libxslt for Windows to test myself.

    For what it's worth, I tried the latest PHP release 7.2.12 on Windows which has the latest libxslt 1.1.32 and it exhibits the problem, so I have opened an issue on libxslt at gitlab.gnome.org/GNOME/libxslt/issues/6 to see whether they consider it a bug.

I've got this php snippet:



$xsltPath = $argv[1];

$xmlPath = $argv[2];



$xslt = file_get_contents($xsltPath);

$xml = file_get_contents($xmlPath);



$templateCMSObj = new DOMDocument();

$templateCMSObj->loadXML($xslt);

$ekbXMLObj = new DOMDocument();

$ekbXMLObj->loadXML($xml);

$proc = new XSLTProcessor();

$proc->importStylesheet($templateCMSObj);

$html = $proc->transformToXML($ekbXMLObj);

echo($html);

exit;


Which simply applies an XSLT to a given XML document.



When I apply the below XSLT to the same XML doc I got a different behaviour of Windows wrt to Linux PHP version.

By changing xsl:number count attribute to * instead of node() the xslt template works as expected on both Win and Linux.

php xml xslt xslt-1.0 libxslt







share|improve this question















I've got this php snippet:



$xsltPath = $argv[1];

$xmlPath = $argv[2];



$xslt = file_get_contents($xsltPath);

$xml = file_get_contents($xmlPath);



$templateCMSObj = new DOMDocument();

$templateCMSObj->loadXML($xslt);

$ekbXMLObj = new DOMDocument();

$ekbXMLObj->loadXML($xml);

$proc = new XSLTProcessor();

$proc->importStylesheet($templateCMSObj);

$html = $proc->transformToXML($ekbXMLObj);

echo($html);

exit;


Which simply applies an XSLT to a given XML document.



When I apply the below XSLT to the same XML doc I got a different behaviour of Windows wrt to Linux PHP version.



Here's php and libxml version detail:

    This is very interesting! Issue can even be reproduced in xslt fiddle, toggling the engine between Saxon and others to "client-side processor".

    This would be much easier (and more useful to others) if the example were minimized to only what's necessary to show the problem - see: Minimal, Complete, and Verifiable example.

    At xsltfiddle.liberty-development.net/6qVRKxe/2 I have tried to make a reduced test case, with Chrome (at least my current version 70.0.3538.102 on Windows 10 64-bit) it shows the problem. @nwellnhof, is that a bug in the Windows version of libxslt? I am having a hard time to find an up to date binary of xsltproc/libxslt for Windows to test myself.

    For what it's worth, I tried the latest PHP release 7.2.12 on Windows which has the latest libxslt 1.1.32 and it exhibits the problem, so I have opened an issue on libxslt at gitlab.gnome.org/GNOME/libxslt/issues/6 to see whether they consider it a bug.

    This is very interesting! Issue can even be reproduced in xslt fiddle, toggling the engine between Saxon and others to "client-side processor".

    This would be much easier (and more useful to others) if the example were minimized to only what's necessary to show the problem - see: Minimal, Complete, and Verifiable example.

    At xsltfiddle.liberty-development.net/6qVRKxe/2 I have tried to make a reduced test case, with Chrome (at least my current version 70.0.3538.102 on Windows 10 64-bit) it shows the problem. @nwellnhof, is that a bug in the Windows version of libxslt? I am having a hard time to find an up to date binary of xsltproc/libxslt for Windows to test myself.

In the select attribute of xsl:number, use * instead of node().



When you use node(), that can be an element, text, comment, or processing instruction node.



When you use *, that's only an element. That makes more sense in your use of xsl:number.



See https://xsltfiddle.liberty-development.net/nc4NzRq/1 for a working fiddle. (Thanks @parfait!)

    @Parfait, I would say it is a bug in libxslt in that particular PHP or Chrome version, not sure whether it is OS related or not. Both Chrome and PHP use libxslt for XSLT processing, so it is not surprising the XSLT problem occurs in PHP and Chrome.

  • Indeed @MartinHonnen. Chrome was the only browser that I could replicate the NaN behavior. And interestingly, the bug is OS-dependent. Modules in Perl, Python, even R (much of the open source) uses libxslt. Bugs can be reported via bugzilla, with some entries for xsl:number.
