基本上规则是:
以下是我使用MarcoS关于params的提示的解决方案:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes" omit-xml-declaration="no" />
<xsl:param name="range-1-begin" select="3"/>
<xsl:param name="range-1-end" select="4"/>
<xsl:param name="range-2-begin" select="6"/>
<xsl:param name="range-2-end" select="7"/>
<xsl:template match="file">
<marco>
<xsl:for-each select="row">
<xsl:if test="(position() >= $range-1-begin and position() <= $range-1-end)
or (position() >= $range-2-begin and position() <= $range-2-end)">
<row>
<xsl:for-each select="cell">
<xsl:if test="position() = 1 or
position() = 3">
<cell>
<xsl:value-of select="."/>

</xsl:for-each>
</row>
</xsl:if>

这是一个可能的解决方案(可能不是很优雅):
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output method="xml" indent="yes" omit-xml-declaration="no" />
<xsl:template match="file">
<file>
<xsl:for-each select="row">
<xsl:if test="(position() >= 3 and position() < 5)
or (position() >= 7 and position() <= 8)">
<row>
<xsl:for-each select="cell">
<xsl:if test="position() = 1 or
position() = 3">
<cell>
<xsl:value-of select="."/>
</cell>
</xsl:if>
</xsl:for-each>
</row>
</xsl:if>
</xsl:for-each>
</file>
</xsl:template>
</xsl:stylesheet>

实际上,您可以使用XPath position()函数来选择所需的范围row和cell元素.
