I'm a newby and have a problem of searching for a value in a xml node tree with a key, maybe someone can help me with this:
I have a variable $myElement and the value is a nodetree something like this:
<nodetree>
   <xsd:sequence>
      <xsd:element ref="A">
      <xsd:element ref="B">
   </xsd:sequence>
</nodetree>

I have defined a key like this:
<xsl:key name="searchtree" match="xsd:sequence/xsd:element" use="string(@ref)" />

I want to check if variable $myValue is in the tree. For instance with the value "B".
I tried this but I never get any results

• <xsl:if test="$myElement/key('searchtree',$myValue)"/>
• <xsl:variable name="myTest" select="$myElement/key('searchtree',$myValue)"/>

What am i doing wrong.:(

Note that using key() on the rhs of "/" is allowed only in XSLT 2.0.

Apart from that, I can't see anything wrong. Try submitting a complete but small example.

Found the problem. It seems that my keyboard has been switched into dutch keyboard settings and the quote was something different. When switching to english keyboard and retype the key value it worked.
And later changed the key like this.


    <xsl:key name="lomchild" match="xsd:schema/xsd:complexType[@name = 'lomType']/xsd:sequence/xsd:element" use="@ref"/>
    ...

    <xsl:variable name="mainPattern" select="key('lomchild',$refNode)"/>

instead of


    <xsl:key name="lomchild" match="xsd:sequence/xsd:element" use="@ref"/>
    ...

    <xsl:variable name="mainPattern" select="xsd:schema/xsd:complexType[@name = 'lomType']/key('lomchild',$refNode)"/>
