XSLT 1.0文档方法没有返回节点集

Question

我正在尝试在XSLT 1.0中使用文档功能，但我没有运气。

我正在转换以下XML

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<items>
  <item>
    <item_number>ZZZ1112</item_number>
    <addl_descr_1><![CDATA[Fudge It Kit Item 1 TEST]]></addl_descr_1>
    <is_txbl>Y</is_txbl>
    <stk_unit>EACH</stk_unit>
    <item_vend_no>5338</item_vend_no>
    <weight>1.0000</weight>
    <prof_alpha_1><![CDATA[MPEX]]></prof_alpha_1>
    <prof_alpha_2><![CDATA[Nikon]]></prof_alpha_2>
    <prof_alpha_3><![CDATA[77mm]]></prof_alpha_3>
    <prof_alpha_4><![CDATA[Telephoto]]></prof_alpha_4>
    <prof_alpha_5><![CDATA[501-1000]]></prof_alpha_5>
  </item>
</items>

使用以下xslt

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:msxsl="urn:schemas-microsoft-com:xslt" exclude-result-prefixes="msxsl"
>
  <xsl:output method="xml" indent="yes"/>

  <xsl:variable name="manufacturer-top" select="msxsl:node-set(document('manufacturer.xml'))" />

  <xsl:template match="/items">
    <items>
      <xsl:for-each select="item">
        <item>
          <xsl:variable name="man" select="prof_alpha_1" />
          <manufacturer>
            <xsl:value-of select="$man"/>
          </manufacturer>
          <id>
            <xsl:value-of select="$manufacturer-top/select[@id='manufacturer'][option = $man]/@value"/>
          </id>
        </item>
      </xsl:for-each>
    </items>
  </xsl:template>

</xsl:stylesheet>

并使用以下“查找”xml文档

<?xml version="1.0" encoding="utf-8" ?>
<select id="manufacturer">

每次我尝试调试变量manufacturer-top时，值始终是lookup xml的值，而不是我可以使用XPath的节点集。非常感谢任何帮助！

Answer 1

document()返回一个节点集，使得select="document(...不是select="msxsl:node-set(document node-set（）接受结果树片段并返回一个节点集，这里不需要，

但你真正的错误是

select="$manufacturer-top/select[@id='manufacturer'][option = $man]/@value"/>

选择您想要的value select属性

    select="$manufacturer-top/select[@id='manufacturer']/option[. = $man]/@value"/>

虽然如果你拥有xxx/foo[.=$bar]，你可能会通过使用密钥来获得更大的加速。

将其添加到样式表

<xsl:key name="op" match="option" use="."/>

然后替换

<xsl_value-of select="$manufacturer-top/select[@id='manufacturer']/option[. = $man]/@value"/>

通过

<xsl:for-each select="$manufacturer-top">
  <xsl:value-of select="key('op',$man)/@value"/>
</xsl:for-each>

除非您的xslt优化器是智能的，否则第一个会对每个齿的整个列表进行线性搜索，第二个将读取列表一次并制作快速哈希查找表。
