平xml到与新标签分层xml

Question

我有这个xml，我需要风格，但无法甚至得到一个for.each正常工作：我尝试，为每个CONNECTIVITY_MESSAGE_LINE，如果名称是'头'然后...

我需要帮助上手......这样我至少可以得到纠正的语句，我已经阅读并阅读...

<?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:template match="@* | node()"> 
    <xsl:element name="SEPA_HEADER"> 
     <xsl:value-of select=". = HEADER"/> 
     <xsl:if test="*//NAME[text() = 'HEADER']"> 
      <p>x</p>   
     </xsl:if>    
     <xsl:for-each select="CONNECTIVITY_MESSAGE/MESSAGE_LINE/CONNECTIVITY_MESSAGE_LINE"> 
      <P>1</P> 
     <xsl:choose> 
      <xsl:when test="//NAME[text() = 'HEADER']"> 
      <P>CHOOSE</P> 
      </xsl:when> 
      <xsl:otherwise> 
      <p>123</p> 
      </xsl:otherwise> 
     </xsl:choose> 
     </xsl:for-each> 
     </xsl:element> 
    </xsl:template> 
</xsl:stylesheet>

从您的文章中您不清楚输出XML需要什么。对于处理输入XML的更多XSL-y方式，我会提出以下建议。使用模板可以避免需要使用for-each的方式，而您似乎试图使用它。

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:xs="http://www.w3.org/2001/XMLSchema" 

    exclude-result-prefixes="xs" 
    version="2.0" 

    xmlns="urn:ifsworld-com:connectivity_message" 
    xpath-default-namespace="urn:ifsworld-com:connectivity_message"> 
    <!-- Note the `xpath-default-namespace` line here: this is only allowed in XSLT 2.0 and newer. 
     The input XLIFF file itself specifies this URI as the unprefixed namespace for the whole file. 
     If we don't specify this as the XPath default namespace, we have to specify element names 
     in ugly workaround syntax, such as `*[local-name() = 'MESSAGE_LINES']`. --> 

    <!-- Indent for easier human readability. --> 
    <xsl:output method="xml" indent="yes"/> 

    <!-- Strip space so that skipped elements don't result in blank whitespace in the output. --> 
    <xsl:strip-space elements="*"/> 

    <!-- Start at the top --> 
    <xsl:template match="/CONNECTIVITY_MESSAGE"> 
     <!-- Here, we just copy the element. Change if you need something different in your output. --> 
     <xsl:copy> 
      <!-- I assume here that you want to also copy over all of the elemnt attributes. --> 
      <xsl:copy-of select="@*"/> 
      <!-- Now, just pass in all the children elements for further processing. --> 
      <xsl:apply-templates/> 
     </xsl:copy> 
    </xsl:template> 

    <xsl:template match="MESSAGE_LINES"> 
     <!-- From your sample code, I have no clear idea if this is what 
      you intend for the SEPA_HEADER element. Change as appropriate. --> 
     <SEPA_HEADER> 
      <!-- Now pass in all children of the MESSAGE_LINES element 
       (in this case, all the CONNECTIVITY_MESSAGE_LINE structures).--> 
      <xsl:apply-templates/> 
     </SEPA_HEADER> 
    </xsl:template> 

    <xsl:template match="CONNECTIVITY_MESSAGE_LINE"> 
     <xsl:copy> 
      <!-- Your sample code had: 
        <xsl:when test="//NAME[text() = 'HEADER']"> 
       The // here means that this is TRUE if there is *any* 
       NAME *anywhere in the file* that has text of 'HEADER'. 
       Given your sample file, this will *always* be true, no 
       matter where we are. I suspect you instead need to 
       check if _this specific CONNECTIVITY_MESSAGE_LINE_ has 
       a NAME element with text of 'HEADER'. --> 
      <xsl:choose> 
       <!-- You can test the text value of an element by simply evaluating `.` ("this"). 
        You can, but you don't need to, evaluate using `text()`. --> 
       <xsl:when test="NAME[. = 'HEADER']"> 
        <p>CHOOSE</p> 
       </xsl:when> 
       <xsl:otherwise> 
        <p>123</p> 
       </xsl:otherwise> 
      </xsl:choose> 
      <!-- I assume here that you want to copy all the children. 
       Change as appropriate for your needs. --> 
      <xsl:copy-of select="*"/> 
     </xsl:copy> 
    </xsl:template> 

    <!-- Suppress output of anything else for which we do not have a specific template defined. --> 
    <xsl:template match="*"/> 

</xsl:stylesheet>
