More of the same . . . surely missing the obvious here . . . 

If I have

<?xml version="1.0"?>
<marc>
	<record>
				<data-field tag="040">
			<subfield code="c">ATLA</subfield>
		</data-field>
		<data-field tag="100" ind1="1">
			<subfield code="a">Hull, John.</subfield>
		</data-field>
		<data-field tag="773" ind1="0">
			<subfield code="g">21 (Aut 1998), p.
5-6</subfield>
			<subfield code="x">0141-6200</subfield>
		</data-field>
	</record>
	<record>
		<data-field tag="040">
			<subfield code="c">ATLA</subfield>
		</data-field>
		<data-field tag="100" ind1="1">
			<subfield code="a">Malone, Patricia.</subfield>
		</data-field>
				<data-field tag="773" ind1="0">
			<subfield code="g">22 (Aut 1998), p.
7-19</subfield>
			<subfield code="x">0000-1234</subfield>
		</data-field>
	</record>
</marc>

and I only want ot pull out those few <record>'s with given content in
data-field[@tag='773']/subfield[@code='g'] --in other words a
record with text string 0000-1234 in subfield[@code='g'] of
data-field[@[tag='773'] ALONG WITH a test string of say "21 " (note the
space- do I use &#?) in subfield[@code='x'] of same datafield[@tag='773']
in that record, what gives?  I'm using 

<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                version="1.0">

<xsl:output type="xml" indent="yes"/>

<xsl:template match="marc">

<xsl:copy>
<xsl:apply-templates select="record[*[@tag='773']/*[@code='g'
[contains(., '21 ')]] 
and record[*[@tag='773']/*[@code='x'
[contains(., '0141-6400')]]"/>
</xsl:copy>
</xsl:template>

</xsl:stylesheet>

And I keep getting the error that line 10 (where the "select" begins)
can't be converted to a node set.  I need to get all elements and
attributes and text of any record which has 0141-6400 as teh text of the x
subfield of data-field 773 _AND_ 21&nbsp; of the g subfield in the 773
data field also.
