I'm using xsltproc on OS X 10.5 (Leopard), XSLT 1.0.
I have an input xml file of n-ary trees. Here's a simplified example
of the input:
<Tree>
<Node Cat="S" Head="0">
<Node Id="3.1" Cat="CL" Start="0" End="1" Rule="V2CL"
Head="0" Type="Verbal">
<Node Id="3.2" Cat="V" Start="0" End="1" Rule="Vp2V" Head="0">
<Node Id="3.3" Cat="vp" Start="0" End="1" Rule="V2VP" Head="0">
<Node Id="3.4" Cat="verb" Start="0" End="1"
Rule="VerbX" Head="0">
<Node Id="3.5" Cat="verb" Start="0" End="0" Lemma="SWR">
S71W.R
</Node>
<Node Id="3.6" Cat="x" Start="1" End="1" Lemma="H"">
FH
</Node>
</Node>
</Node>
</Node>
</Node>
</Node>
</Tree>
What I want to do is to extract the contents of the Lemma attribute
whenever the Cat attribute is "x" into a simple text file. Here is the
stylesheet so far:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="Node[(_at_)Cat='x']">
<xsl:value-of select="@Lemma"/>
</xsl:template>
</xsl:stylesheet>
Expected output (from this simplified example input):
H
What I get is:
S71W.R
H
That is I get what I want, but I *also* get the contents of all Node
elements but, interestingly I don't get the element content of the
Node that is Cat="x".
What I've read and researched today says I'm doing what I want, but
obviously I'm missing something basic. Why am I getting all this extra
Node element content of the file in the output?
Thanks.
