问题描述
我正在尝试编写 XSLT，它将在选定的后续兄弟姐妹上运行 for-each，但在到达另一个标记 (h1) 时停止.
I am attempting to write XSLT that will run a for-each on the selected following-siblings but stop when another tag (h1) is reached.
这是源 XML:
<?xml version="1.0"?>
<html>
<h1>Test</h1>
<p>Test: p 1</p>
<p>Test: p 2</p>
<h1>Test 2</h1>
<p>Test2: p 1</p>
<p>Test2: p 2</p>
<p>Test2: p 3</p>
</html>
这是 XSLT:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<content>
<xsl:apply-templates/>
</content>
</xsl:template>
<xsl:template match="h1">
<section>
<sectionHeading>
<xsl:apply-templates/>
</sectionHeading>
<sectionContent>
<xsl:for-each select="following-sibling::p">
<paragraph>
<xsl:value-of select="."/>
</paragraph>
</xsl:for-each>
</sectionContent>
</section>
</xsl:template>
<xsl:template match="p"/>
</xsl:stylesheet>
这是当前的结果:
<?xml version="1.0" encoding="UTF-8"?>
<content>
<section>
<sectionHeading>Test</sectionHeading>
<sectionContent>
<paragraph>Test: p 1</paragraph>
<paragraph>Test: p 2</paragraph>
<paragraph>Test: p 3</paragraph>
<paragraph>Test2: p 1</paragraph>
<paragraph>Test2: p 2</paragraph>
</sectionContent>
</section>
<section>
<sectionHeading>Test 2</sectionHeading>
<sectionContent>
<paragraph>Test2: p 1</paragraph>
<paragraph>Test2: p 2</paragraph>
</sectionContent>
</section>
</content>
这是预期的结果:
<?xml version="1.0" encoding="UTF-8"?>
<content>
<section>
<sectionHeading>Test</sectionHeading>
<sectionContent>
<paragraph>Test: p 1</paragraph>
<paragraph>Test: p 2</paragraph>
<paragraph>Test: p 3</paragraph>
</sectionContent>
</section>
<section>
<sectionHeading>Test 2</sectionHeading>
<sectionContent>
<paragraph>Test2: p 1</paragraph>
<paragraph>Test2: p 2</paragraph>
</sectionContent>
</section>
</content>
推荐答案
试试这个:(而不是要求所有的 p，我们要求所有最近在 h1 之前的 p 是当前的.)
Try this: (Instead of asking for all the p's we ask for all the p's whose most recently preceding h1 is current.)
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
<content>
<xsl:apply-templates/>
</content>
</xsl:template>
<xsl:template match="h1">
<xsl:variable name="header-id" select="generate-id(.)"/>
<section>
<sectionHeading>
<xsl:apply-templates/>
</sectionHeading>
<sectionContent>
<xsl:for-each select="following-sibling::p[generate-id(preceding-sibling::h1[1]) = $header-id]">
<paragraph>
<xsl:value-of select="."/>
</paragraph>
</xsl:for-each>
</sectionContent>
</section>
</xsl:template>
<xsl:template match="p"/>
</xsl:stylesheet>
