Question

我有一个使用外部文件的xsl。 xsl包含xsl：key元素，当使用外部文档时，这不能正常工作。

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:output method="html" encoding="utf-8"/>
  <xsl:param name="People"></xsl:param>
  <xsl:param name="Abstracts"></xsl:param>
  <xsl:key name="uniqueAfflTags" match="AFFL" use="concat(../../../../@id,@number)"/>
  <xsl:variable name="abstracts" select="document($Abstracts)//ABSTRACT"/>

<!--Root template -->
  <xsl:template match="/">
    <html>
      <head>
      <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"/>
      </head>
      <body>
        <xsl:apply-templates select="//PRESENTATIONS/PRESENTATION[@type!='placeholder']">
          <xsl:sort select="AUTHORS/AUTHOR[1]/LNAME"/>
        </xsl:apply-templates>
      </body>
    </html>
  </xsl:template>

  <xsl:template match="PRESENTATION">
    <xsl:variable name="ctrlid" select="@control_id"/>
    <xsl:text> </xsl:text>
    <!--  Category -->
    <xsl:if test="string-length($abstracts[@id=$ctrlid]/ABSTRACT_CATEGORY/CATEGORY_GROUP/CATEGORY) &gt; 0">
      <xsl:text> - </xsl:text>
      <span class="Category">
        <xsl:value-of select="$abstracts[@id=$ctrlid]/ABSTRACT_CATEGORY/CATEGORY_GROUP/CATEGORY"/>
      </span>
    </xsl:if>
    <xsl:apply-templates select="descendant::AFFL">
      <xsl:sort select="@number" data-type="number"/>
    </xsl:apply-templates>
  </xsl:template>

  <xsl:template match="AFFL">
    <xsl:if test="generate-id()=generate-id(key('uniqueAfflTags',concat(../../../../@id,@number))[1])">
      (<xsl:value-of select="@number"/>)
      <xsl:if test="string-length(DEPT) &gt; 0">
        <xsl:value-of select="DEPT"/>
      </xsl:if>

      <xsl:if test="string-length(INST) &gt; 0">
        <xsl:if test="string-length(DEPT) &gt; 0">
          <xsl:text>, </xsl:text>
        </xsl:if>
        <xsl:value-of select="INST"/>
      </xsl:if>

      <xsl:if test="string-length(CITY) &gt; 0">
        <xsl:if test="string-length(INST) &gt; 0 or string-length(DEPT) &gt; 0">
          <xsl:text>, </xsl:text>
        </xsl:if>
        <xsl:value-of select="CITY"/>
      </xsl:if>

      <xsl:if test="string-length(STATE) &gt; 0">
        <xsl:if test="string-length(CITY) &gt; 0 or string-length(INST) &gt; 0 or string-length(DEPT) &gt; 0">
          <xsl:text>, </xsl:text>
        </xsl:if>
        <xsl:value-of select="STATE"/>
      </xsl:if>

      <xsl:if test="string-length(COUNTRY) &gt; 0">
        <xsl:if test="COUNTRY!='United States'">
          <xsl:if test="string-length(STATE) &gt; 0 or string-length(CITY) &gt; 0 or string-length(INST) &gt; 0 or string-length(DEPT) &gt; 0">
            <xsl:text>, </xsl:text>
          </xsl:if>
          <xsl:value-of select="COUNTRY"/>
        </xsl:if>
      </xsl:if>
    </xsl:if>
  </xsl:template>

  <xsl:template match="text()">
  </xsl:template>
</xsl:stylesheet>

使用当前的xsl，AFFL模板匹配中的if条件不满意。如果我删除这些行：

<xsl:variable name="ctrlid" select="@control_id"/>
    <xsl:text> </xsl:text>
    <!--  Category -->
    <xsl:if test="string-length($abstracts[@id=$ctrlid]/ABSTRACT_CATEGORY/CATEGORY_GROUP/CATEGORY) &gt; 0">
      <xsl:text> - </xsl:text>
      <span class="Category">
        <xsl:value-of select="$abstracts[@id=$ctrlid]/ABSTRACT_CATEGORY/CATEGORY_GROUP/CATEGORY"/>
      </span>
    </xsl:if>

它开始工作。问题看起来像是不正确的上下文，但我无法正确设置上下文。很感谢任何形式的帮助。感谢

如果它确实是一个上下文问题，那么我该如何选择基础文档的上下文。

Answer 1

密钥索引是按文档构建的，密钥函数适用于当前上下文节点的文档，因此通常需要多个文档来确保使用例如更改上下文。

<xsl:variable name="some-key-value" select="foo"/>
<xsl:for-each select="$otherDoc">
  <xsl:apply-templates select="key('key-name', $some-key-value)"/>
</xsl:for-each>

在XSLT 1.0或XSLT 2.0中，您可以将其缩短为

<xsl:apply-templates select="key('key-name', foo, $otherDoc)"/>

如果您需要更具体的帮助，请告诉我们您输入文档的结构。

转换多个文档上下文
