我正在尝试为我的html输出添加锚点。使用xsl 2.0创建html以将xml转换为html。我需要能够将正则表达式列表传递到我的样式表中，并将正则表达式列表的每个匹配实例都作为锚点。我有一个适用于单个正则表达式的代码，但是当我通过i运行正则表达式列表时，获得相同段落的倍数。我绝不是xsl 2.0的专家。我不确定这样做是否可行。我也可以使用c＃，如果这更容易的话。如果有人认为这将是一个更好的解决方案，虽然我不确定它是什么。
适用于单个正则表达式的代码是：
<xsl:template match="text()" mode="content">
<xsl:variable name="text">
<xsl:value-of select="."></xsl:value-of>
</xsl:variable>
<!--
IndexTerms is a parameter passed into the sheet it is a list of regex expressions seperated by semi colons
-->
<xsl:for-each select="tokenize($IndexTerms, ';')">
<xsl:call-template name="IndexTerm">
<xsl:with-param name="matchedRegex">
<xsl:text>(.*)(</xsl:text>
<xsl:value-of select="."></xsl:value-of>
<xsl:text>)(.*)</xsl:text>
</xsl:with-param>
<xsl:with-param name="text">
<xsl:value-of select="$text"></xsl:value-of>
</xsl:with-param>
</xsl:call-template>
</xsl:for-each>
</xsl:template>
<xsl:template name="IndexTerm">
<xsl:param name="matchedRegex">
<xsl:text>asdf</xsl:text>
</xsl:param>
<xsl:param name="text"></xsl:param>
<xsl:analyze-string select="$text" regex="{$matchedRegex}" flags="m">

</xsl:with-param>
<xsl:with-param name="matchedRegex">
<xsl:value-of select="$matchedRegex"></xsl:value-of>
</xsl:with-param>
</xsl:call-template>
<xsl:element name="a">
<xsl:attribute name="class">
<xsl:text>IndexAnchor</xsl:text>
</xsl:attribute>
<xsl:value-of select="regex-group(2)"></xsl:value-of>
</xsl:element>
<xsl:value-of select="regex-group(3)"></xsl:value-of>

坦率地说，不是用分号分隔不同的模式，我强烈建议使用条形“|”这是用于分隔备选方案的正则表达式语言字符。然后，您只需将完整参数提供给analyze-string：
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
version="2.0"
exclude-result-prefixes="xs">
<xsl:param name="patterns" as="xs:string" select="'Digital Televisions?|Internet'"/>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@*, node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="text()">
<xsl:analyze-string select="." regex="{$patterns}">
<xsl:matching-substring>
<a class="IndexAnchor">
<xsl:value-of select="."/>
</a>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>
</xsl:stylesheet>
这有帮助吗？如果您需要将分号分隔列表转换为分隔的条形，请执行以下操作： <xsl:param name="patterns" as="xs:string" select="string-join(tokenize($yourParam, ';'), '|')"/>。
我没有使用模式，也没有看过你可能想要做的任何其他转换，但当然你应该能够使用我在模板中提供的模板（如果需要的话）。
