我面临以下问题：
我有源XML文件：
<TABLE NAME="TEST">
<DATA RECORDS="78">
<catalog>
<book id="bk109">
<description>An anthology of horror stories about roaches, centipedes, scorpions and other insects.</description>

</DATA>
</TABLE>
给出以下xsl：
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"
xmlns:xs="http://www.w3.org/2001/XMLSchema"

exclude-result-prefixes="xs functx">
<xsl:param name="search-text" as="xs:string">An anthology of horror stories about roaches, centipedes, scorpions and other insects.
Microsoft's .NET initiative is explored in detail in this deep programmer's reference.</xsl:param>
<xsl:param name="replacement-text" as="xs:string">Value we need to store in the (description) element.

<xsl:param name="search-terms" as="xs:string*" select="tokenize($search-text, '\r?\n')"/>
<xsl:param name="search-terms-is" as="xs:string*" select="for $term in $search-terms return concat('^', lower-case(functx:escape-for-regex($term)), '$')"/>
<xsl:param name="replace-terms" as="xs:string*" select="tokenize($replacement-text, '\r?\n')"/>
<xsl:include href="http://www.xsltfunctions.com/xsl/functx-1.0-nodoc-2007-01.xsl"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="description[some $search-term in $search-terms-is satisfies matches(., $search-term, 'i')]">
<xsl:copy>
<xsl:variable name="matched-term" as="xs:string" select="$search-terms-is[matches(current(), ., 'i')]"/>

<xsl:value-of

</xsl:copy>
</xsl:template>

结果还可以：

但如果在搜索字词中，我有两倍相同的字词，在不同情况下，我会收到错误

我怎么能改变样式表，以免发生这种错误？ 这个例子是由Martin Honnen在线上传的，他很友好地回答了我之前提出的问题。 在线http://xsltransform.net/gVhD8RA
