Is it possible to access the textnode of a node-set with a key function in xslt 1.0? I have following code:

<xsl:variable name="Items">
        <Item ID="ID1">name1</Item>
        <Item ID="ID2">name2</Item>
</xsl:variable>

<xsl:key name="get_item_by_ID" match="exsl:node-set($Items)/Item" use="@ID"/>

<xsl:template match="/Items">
    <xsl:value-of select="key('get_item_by_ID', @ItemID)/text()"></xsl:value-of>
 </xsl:template>

I want to search for the text of the node-set by the ItemID of the current Item, in order to rename the Item by it's predefined node-set text (ID1: name1, ID2: name2).

You have a context issue here:

The node-set created by exsl:node-set($Items) is a separate "document". You cannot specify the document to match within the match attribute of a <key> element.

You must switch the context to the desired document before you call the key() function (in XSLT 2.0 you can specify the document to match within the key() function itself).

  • Thanks I didn't know this. What do you mena with "switch de context do the desired document"? How can I realize that? – nh_ Nov 17 '14 at 10:09
  • You can switch context by using `xsl:for-each`, for example ``. See an example of that in your previous question: http://stackoverflow.com/questions/26889758/xslt-node-set-use-in-key-function-find-children-by-parent-attribute – michael.hor257k Nov 17 '14 at 11:09
