I've xml code like this:
roles.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<roles xmlns="http://www.wolterinkwe bdesign.com/xml/roles">
<!--
! The admin role.
! And admin should have all permisions to do its task
!
!-->
<role id="admin" isadmin="true">
<name>Administr ator</name>
<description> De Administrator kan alles verwijderen, toevoegen en bewerken op de site.</description>
<grants>
<for name="all">
<action name="edit" grant="true" />
<action name="new" grant="true" />
<action name="read" grant="true" />
</for>
</grants>
</role>
<!--
! A generic visitor role.
! Anybody who is not given a role explicit is a visitor
!-->
<role id="visitor" isvisitor="true ">
<name>Bezoeke r</name>
<description>Be zoeker van de site</description>
a
<grants>
b
<for name="all">
<action name="read" grant="true" />
<action name="edit" grant="true" />
</for>
<for name="gastenboe k">
<action name="new" grant="true"/>
<action name="edit" grant="true" />
</for>
<for name="medewerke rs">
<action name="new" grant="true"/>
</for>
<for name="files">
y
<action name="new" grant="true">d</action>
</for>
<for name="news">
<action name="new" grant="true"/>
</for>
</grants>
</role>
</roles>
XSL code like this:
ps, $roles is always the above roles.xml
<!--
This template below works on for example
<page:button-edit-delete module="files" id="3"/>
-->
<xsl:template match="page:but ton-edit-delete">
<xsl:if test="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]/r:action[@name='edit']/@grant='true' or $roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='all']/r:action[@name='edit']/@grant='true'">
<[cut]
</xsl:if>
</xsl:template>
<!--
This template below does NOT work on for example
<page:button-new module="files" id="3"/>
-->
<xsl:template match="page:but ton-new">
<!-- debug code -->
BUTTON NEW MATCHED!
<xsl:value-of select="./@module"/>
<xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]"/>
<xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='files']"/>
<!-- end debug code -->
<xsl:if test="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]/r:action[@name='new']/@grant='true' or $roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='all']/r:action[@name='new']/@grant='true'">
[cut]
</xsl:if>
</xsl:template>
Strange enough:
this works: <xsl:value-of select="./@module"/> output:files
this does not work:
<xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]"/> output= ""
and this does work:
<xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='files']"/>
I do not understend the if test in the second template is almost the same as in the first template, but the first template always works and
the second not..... i cannot find the error 4 1544
[cut]
i've had the following solution:
<!--
! Matches a new button
!-->
<xsl:template match="page:but ton-new">
<xsl:variable name="module" select="./@module"/>
<xsl:if test="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=$module]/r:action[@name='new']/@grant='true' or $roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='all']/r:action[@name='new']/@grant='true'">
<div class="new_butt on">
<form enctype="multip art/form-data" action="$php_se lf" method="post">
<input type="hidden" name="module" value="{@module }" />
<input type="hidden" name="name" value="{@multip le}" />
<input type="hidden" name="new_reque st" value="true" />
<input class="new_butt on" type="submit" value="Nieuw item toevoegen" />
</form>
</div>
</xsl:if>
</xsl:template>
But that is ugly!! I think it must be possible without the xsl:variable
> Strange enough: this works: <xsl:value-of select="./@module"/> output:files this does not work: <xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]"/> output= "" and this does work: <xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='files']"/>

Hi,
you could use this:
<xsl:copy-of select="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=current()/@module]"/>
Explanation:
In this Xpath expression:
<xsl:value-of select="./@module"/>
the period (.) selects the context node, which - in this case- is equal to the current node-set of the template.
But between the [brackets] in:
<xsl:copy-of select="/r:for[@name=./@module]"/>
, the context node is changed to the node preceding the left bracket ('r:for'). So this expression is trying to access the 'module' attribute of 'r:for'. In other words, you cannot access the current node-set with '.' when you're between brackets. You have to use 'current()' in stead.
regards,

i thought of that, but i did not know current() existed.
But then how do you explain that this template works:
<xsl:template match="page:but ton-edit-delete">
<xsl:if test="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]/r:action[@name='edit']/@grant='true' or $roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='all']/r:action[@name='edit']/@grant='true'">
[cut]
</xsl:if>
</xsl:template>
And this one not:
<xsl:template match="page:but ton-new">
<xsl:if test="$roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name=./@module]/r:action[@name='new']/@grant='true' or $roles/r:roles/r:role[@id=$role]/r:grants/r:for[@name='all']/r:action[@name='new']/@grant='true'">
[cut]
</xsl:if>
</xsl:template>
I do not understand that. the only differences ar in @name='edit' or @name='new' and in the match attribute of xsl:template.
Maybe i should give more detail?

I'm not really sure either. One guess is that there's an 'action' node in your XML that does not have a 'name' attribute. That node would match the XPath expression because its non-existing 'name' attribute woulkd its non-existing 'module' attribute.
btw, I think it would be better to use a shorter notation like this:
<xsl:if test="//r:roles/r:role[@id=$role]/r:grants/r:for[@name='all' or @name=current()/@module]/r:action[@name='new']/@grant='true'">

I refined my attempt a little further, and the following code does
seem to work, however it has 2 major problems:
1. Very limited support for XPath features
Basic paths are supported for elements, attributes, ".", and "..",
plus also the "" predicate format is supported -
however, only one predicate per path step is supported, and expr must
be a relative path.
2. Poor performance

Poking around with XPath using SimpleXML, it looks like there are at
least a few reasonably common XPath operators and predicates that
aren't supported. I'd like to check my observations against other
people's experience, and find out if I'm missing something.
Here's what it looks like to me in PHP 5.2.0:
