我目前正以这种方式获取描述标记内容：
<description><xsl:value-of select="description" /></description>
如何摆脱img标记中找到的description（可能还有其他）标记？
答案 0 :(得分：1)
在XSLT 1.0中，您需要使用递归命名模板来删除伪标记。这是一个例子：
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="description">
<xsl:copy>
<xsl:call-template name="exclude-markup">
<xsl:with-param name="string" select="." />
</xsl:call-template>
</xsl:copy>
</xsl:template>
<xsl:template name="exclude-markup">
<xsl:param name="string"/>
<xsl:param name="prefix" select="'<'"/>
<xsl:param name="suffix" select="'>'"/>
<xsl:choose>
<xsl:when test="contains($string, $prefix) and contains(substring-after($string, $prefix), $suffix)">
<xsl:value-of select="substring-before($string, $prefix)" />
<!-- recursive call -->
<xsl:call-template name="exclude-markup">
<xsl:with-param name="string" select="substring-after(substring-after($string, $prefix), $suffix)" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$string" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
