无法让我的实际用例工作。我的代码目前是
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template name="bundle-main">
<div
class="container"
data-page-type="bundle"
>
<div class="row">
<xsl:for-each select="//bundles-entry-by-bundle/entry/components/item">
<xsl:variable name="id" select="@id" />
<xsl:if test="@section-handle = 'components-text'">
<xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]">
<xsl:call-template name="components-text"/>
</xsl:for-each>
</xsl:if>
<xsl:if test="@section-handle = 'components-link'">
<xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]">
<xsl:call-template name="components-link"/>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
</div>
</div>
</xsl:template>
</xsl:stylesheet>
打印一行，但需要实现12列包装。我的尝试不值得发布，因为它不太有效。我相信键选择器会像
sum(*[name() = concat($stack-items/@section-handle, '-entry-by-bundle')]/entry[@id = //bundles-entry-by-bundle/entry/components/item/@id]/columns/item/@handle) >= 12 or $i >= count($items)
这是XML

以下是我想用上述XML实现并替换我的XSL的solution。
<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:template match="/root">
<xsl:copy>
<xsl:call-template name="aggregate">
<xsl:with-param name="items" select="item"/>
</xsl:call-template>
</xsl:copy>
</xsl:template>
<xsl:template name="aggregate">
<xsl:param name="items" select="/.."/>
<xsl:param name="i" select="1"/>
<xsl:variable name="stack-items" select="$items[position() <= $i]" />
<xsl:choose>
<xsl:when test="sum($stack-items/@columns) >= 12 or $i >= count($items)">
<row>
<xsl:copy-of select="$stack-items"/>
</row>
<xsl:if test="$i < count($items)">
<xsl:call-template name="aggregate">
<xsl:with-param name="items" select="$items[position() > $i]"/>
</xsl:call-template>
</xsl:if>
</xsl:when>
<xsl:otherwise>
<xsl:call-template name="aggregate">
<xsl:with-param name="items" select="$items"/>
<xsl:with-param name="i" select="$i + 1"/>
</xsl:call-template>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
答案 0 :(得分：3)
这段代码显然是错误的：
//*[concat(@section-handle,'-entry-by-bundle')]
因为在谓词中使用字符串时，如果字符串非空，则有效值为true，这种情况总是如此。
我怀疑您正在尝试选择名称等于（@ section-handle，＆＃39; -entry-by-bundle＆＃39;）的串联的元素。这似乎是您应该使用模板规则而不是命名模板的情况。 （＆＃34; Silly xsl＆＃34;有完美的机制满足您的要求，而您却无视它！）。替换此代码：
<xsl:for-each select="//bundles-entry-by-bundle/entry/components/item">
<xsl:variable name="id" select="@id" />
<!-- silly xsl will not let us programatically call templates -->
<xsl:if test="@section-handle = 'components-text'">
<xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]">
<xsl:call-template name="components-text"/>
</xsl:for-each>
</xsl:if>
<xsl:if test="@section-handle = 'components-link'">
<xsl:for-each select="//*[concat(@section-handle,'-entry-by-bundle')]/entry[@id = $id]">
<xsl:call-template name="components-link"/>
</xsl:for-each>
</xsl:if>
</xsl:for-each>
通过
<xsl:for-each select="//bundles-entry-by-bundle/entry/components/item">
<xsl:apply-templates select="//*[name()=concat(current()/@section-handle, '-entry-by-bundle'/>
</xsl:template>
<xsl:template match="component-text-entry-by-bundle">
<!-- your component-text template -->
</xsl:template>
<xsl:template match="component-link-entry-by-bundle">
<!-- your component-link template -->
</xsl:template>
