[xsl] Xpath Syntax Issue

[Nathan Tallman <ntallman@xxxxxxxxx>]

I'm trying to remove an entire element, if the value of one of its
child elements equals x.

XML Input example:
<pets>
<animal>
    <species>fish</species>
    <environment>bowl</environment>
</animal>

<animal>
    <species>cat</species>
    <environment>house</environment>
</animal>
</pets>

XSLT Goal: Remove all animal elements if species=fish

XML Output desired:
<pets>
<animal>
    <species>cat</species>
    <environment>house</environment>
</animal>
</pets>

Here's my current XSL:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:ead="urn:isbn:1-931666-22-9"
    xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
    exclude-result-prefixes="xsl ead xlink xsi" version="1.0">

    <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

    <xsl:strip-space elements="*"/>

    <!-- Standard copy -->
    <xsl:template match="*">
        <xsl:copy>
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="pets/animal/species[text()='fish']"/>

</xsl:stylesheet>


But all my outputs still have fish. I'm using XSLT 1.0 and I'm having
a problem with the xpath, I think. My XML reference book is at work,
and I can't quite get the xpath syntax right, can someone point out my
error?

Many thanks,
Nathan
