当我尝试基于特定标签生成内容节点列表时，Umbraco，或者更确切地说是 xslt，似乎给了我错误。

考虑宏中的以下代码：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
xmlns:msxml="urn:schemas-microsoft-com:xslt"
xmlns:tagsLib="urn:tagsLib"
xmlns:umbraco.library="urn:umbraco.library" xmlns:Exslt.ExsltCommon="urn:Exslt.ExsltCommon"     xmlns:Exslt.ExsltDatesAndTimes="urn:Exslt.ExsltDatesAndTimes" xmlns:Exslt.ExsltMath="urn:Exslt.ExsltMath" xmlns:Exslt.ExsltRegularExpressions="urn:Exslt.ExsltRegularExpressions" xmlns:Exslt.ExsltStrings="urn:Exslt.ExsltStrings" xmlns:Exslt.ExsltSets="urn:Exslt.ExsltSets" 
exclude-result-prefixes="msxml tagsLib umbraco.library Exslt.ExsltCommon Exslt.ExsltDatesAndTimes Exslt.ExsltMath Exslt.ExsltRegularExpressions Exslt.ExsltStrings Exslt.ExsltSets ">
<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

<xsl:variable name="location"  select="$currentPage/othertag" />

<xsl:template match="/">
<div class="more-news">
  <xsl:value-of select="$currentPage/location"/>
  <h4>More news from <span class="capitalize"><xsl:value-of select="$location"/></span></h4>
  <ul>
    <xsl:for-each select="tagsLib:getEverythingWithTags('somalia')/root/node">
      <li><a href="#"><xsl:value-of select="@nodeName"/></a></li>
      <xsl:value-of select="@nodeUrl"/>
    </xsl:for-each>
  </ul>
</div>
</xsl:template>

</xsl:stylesheet>

我在这里尝试做的是查找所有带有在当前页面上定义的标签（位置）的内容。上述设置适用于查找所有带有位置标签“索马里”的页面。

该行：

<xsl:for-each select="tagsLib:getEverythingWithTags('somalia')/root/node">

应该（我认为）是：

<xsl:for-each select="tagsLib:getEverythingWithTags($location)/root/node">

但是像这样保存代码会给我以下错误：

任何帮助和想法表示赞赏。

您是否使用此行代码检查了“$currentPage/othertag”的内容：

<xsl:value-of select="$currentPage/othertag" />

之后，您应该将此代码行放在 xslt 而不是 foreach 循环中：

<xsl:value-of select="tagsLib:getEverythingWithTags($location)" />

并检查标签的内容。
