The key() function has an implicit dependency on the context node - unless
you supply the new third argument, it searches the current document, defined
as the document containing the context node. But inside an xsl:function,
there is no context node unless you create one. Functions have no implicit
parameters.
If the call on key() is always searching the principal source document of
the transformation, you can set up the usual global variable
<xsl:variable name="root" select="/"/>
and use $root as the third argument of key().
If it's searching different documents on different occasions, then you need
to add another parameter to the function.

Subject: [xsl] Cannot select a node here: the context item is
undefined
Again thank you all for your great responses. I just about have this
project completed.
I am using Saxon 8.3
the piece of the stylesheet giving the error message is >>>marked<<<<<
<xsl:key name="word-group-by-word" match="word-group"
use="word"/>
<xsl:function name="str:find_root_word" as="xs:string">
<xsl:param name="word" as="xs:string"/>
<xsl:variable name="length-of-word" select="
string-length($word)" />
<xsl:choose>
<!-- this should remove the 'ed' -->
<xsl:when test="key('word-group-by-word',substring($word,1,
$length-of-word - 2))"> <<<<<<<<<<<<<<<<<<
<xsl:sequence
select="substring($word,1,
$length-of-word - 2)"/>
</xsl:when>
So what is the error? Cannot select a node here: the context item is
undefined
What I am trying to do.
I have words in word-group that I am trying to analyze. If the
master-count is non-zero then I am happy that we have the
word found in a
Bible and in the master list e.g., falter.
If the master-count is null then it should be flagged as a
possible error.
But since the last three words are only variations of the first word
listed below I would like to exclude them as problems.
<word>falter</word>
<word>faltered</word>
<word>faltering</word>
<word>falters</word>
piece of xml file:
