I have a 'context-free' function which does a key() lookup. However,
saxon is complaining:
SXWN9009: Cannot select a node here: the context item is undefined
Question: How can I say: "Start a key lookup from the root of the file"?
By using the third argument of key(): it is defined as the apex of a
tree under which which the keyed values are searched.
I tried select="\\key('myKey'...." but this didn't work.
So I have:
<xsl:key name="myKey" match="books/book/...." use="..."/>
Add a variable with global scope:
<xsl:variable name="myBooks" match="/"/>
<xsl:function name="...." as="xs:double">
<xsl:param name="input"/>
<xsl:for-each select="key('myKey',$input)">
key('myKey',$input,$myBooks)
processing goes here
</xsl:for-each>
</xsl:function>
I hope this helps.
