好吧，我已经达成了一个完整的心理障碍，试图让它发挥作用，并想知道是否有其他人可能能够解决它。我有以下HTML结构。

    <?xml version="1.0" encoding="utf-8"?>
    <root>
      <listing>
        <name>Frank Spencer</name>
        <dob>2010-09-01</dob>
        <details>
         <firmname>Scotts</firmname>
         <address>Blah Blah</address>
         <businessname>Scotts</businessname>
         <businessaddress>Blahdeblah</businessaddress>
        </details>
        <details>
         <firmname>Scotts</firmname>
         <address>Blah Blah</address>
         <businessname>Wilson and Son</businessname>
         <businessaddress>Blahdeblah</businessaddress>
        </details>
        <details>
         <firmname>Wilson and Son</firmname>
         <address>Blah Blah</address>
         <businessname>Brudebakers</businessname>
         <businessaddress>Blahdeblah</businessaddress>
       </details>
       <details>
         <firmname>Carnage and Co.</firmname>
         <address>Blah Blah</address>
         <businessname>Brudebakers</businessname>
         <businessaddress>Blahdeblah</businessaddress>
       </details>
     </listing>
      <listing>
       <name>Han Solo</name>
       <dob>2010-09-01</dob>
       <details>
         <firmname>Independent trading</firmname>
         <address>Blah Blah</address>
         <businessname>Fugitive freight</businessname>
         <businessaddress>Blahdeblah</businessaddress>
       </details>
       <details>
         <firmname>Scotts</firmname>
         <address>Blah Blah</address>
         <businessname>Wilson and Son</businessname>
         <businessaddress>Blahdeblah</businessaddress>
       </details>
       <details>
         <firmname>Wilson and Son</firmname>
         <address>Blah Blah</address>
         <businessname>Scotts</businessname>
         <businessaddress>Blahdeblah</businessaddress>
       </details>
       <details>
         <firmname>Carnage and Co.</firmname>
         <address>Blah Blah</address>
         <businessname>Brudebakers</businessname>
         <businessaddress>Blahdeblah</businessaddress>
       </details>
    </listing>
</root>

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="html" indent="yes"/>

<xsl:param name="searchName">Wilson</xsl:param>
<xsl:param name="searchName2"></xsl:param>

<xsl:variable name="Uppercase" select="'ABCDEFGHIJKLMNOPQRSTUVWXYZ'"/>
<xsl:variable name="Lowercase" select="'abcdefghijklmnopqrstuvwxyz'"/>

<xsl:template match="/">
    <xsl:for-each select="root/listing">
       <p>Name: <xsl:value-of select="name"/></p>
       <p>DOB: <xsl:value-of select="dob" /></p>

<xsl:for-each select="details[not(firmname=following::root/listing/details/firmname) and not(businessname=following::root/listing/details/businessname) or not(firmname=following::root/listing/details/businessname) or not(businessname=following::root/listing/details/firmname)]"> 

<xsl:choose>

    <xsl:when test="contains(translate(firmname,$Uppercase,$Lowercase), translate($searchName,$Uppercase,$Lowercase)) and contains(translate(businessname,$Uppercase,$Lowercase), translate($searchName,$Uppercase,$Lowercase)) and not($searchName = '')">
 (This individual has previously worked at:
 <xsl:value-of select="firmname" />
 </xsl:when>

 <xsl:when test="contains(translate(businessname,$Uppercase,$Lowercase), translate($searchName,$Uppercase,$Lowercase)) and not(contains(translate(firmname,$Uppercase,$Lowercase), translate($searchName,$Uppercase,$Lowercase))) and not($searchName = '')">
(This individual has previously worked at:
 <xsl:value-of select="businessname" />)
 </xsl:when>

 <xsl:when test="contains(translate(firmname,$Uppercase,$Lowercase), translate($searchName,$Uppercase,$Lowercase)) and not(contains(translate(businessname,$Uppercase,$Lowercase), translate($searchName,$Uppercase,$Lowercase))) and not($searchName = '')">
 (This individual has previously worked at:
 <xsl:value-of select="firmname" />)<br/>
 </xsl:when>

 </xsl:choose>
 </xsl:for-each>
 </xsl:for-each>
 </xsl:template>
 </xsl:stylesheet>

我想要的是获得包含搜索词的公司列表。但我得到的是：

  Name: Frank Spencer

  DOB: 2010-09-01

  (This individual has previously worked at: Wilson and Son)
  (This individual has previously worked at: Wilson and Son)

  Name: Han Solo

  DOB: 2010-09-01

  (This individual has previously worked at: Wilson and Son)
  (This individual has previously worked at: Wilson and Son)

xslt应该同时查看firmname和businessname，然后如果找到与contains匹配的话，它应该只打印一个引用。但我似乎无法让它发挥作用。有没有人有任何解决方案/建议？理想的结果是。 

<body>
  <p>Name: Frank Spencer</p>

  <p>DOB: 2010-09-01</p>

  <p>(This individual has previously worked at: Wilson and Son)</p>


  <p>Name: Han Solo</p>

  <p>DOB: 2010-09-01</p>

  <p>(This individual has previously worked at: Wilson and Son)</p>
</body>
