你能编辑你的问题来显示在这种情况下的预期输出？谢谢。 –

如果您正在寻找排除某些referenceTransaction元素，你真的需要匹配referenceTransaction，在[]条件的模板。就条件而言，你应该改变逻辑。你应该否定它，而不是为了保留你想要保留的条件，而是给出你想要删除的条件。

<xsl:template match="referenceTransaction 
         [rating/effectiveDate='' or not(starts-with(rating/ratingDataModel/ratingChar1,'WL'))]"/>

即删除referenceTransaction如果effectiveDate为空或ratingChar1不WL启动。

但是，您有第二个问题。在您的XML中，您有默认名称空间

xmlns="http://www.eagleinvsys.com/2011/EagleML-2-0"

但是您在XSLT中没有考虑到这一点。如果您确实使用XSLT 2.0，则可以使用xpath-default-namespace来处理此问题。

试试这个XSLT

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0" xpath-default-namespace="http://www.eagleinvsys.com/2011/EagleML-2-0"> 
    <xsl:output method="xml" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" /> 

    <xsl:strip-space elements="*" /> 

    <xsl:template match="node()|@*"> 
    <xsl:copy> 
     <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy> 
    </xsl:template> 

    <xsl:template match="referenceTransaction[rating/effectiveDate='' or not(starts-with(rating/ratingDataModel/ratingChar1,'WL'))]"/> 
</xsl:transform>

但是，如果你正在使用XSLT 1.0，你必须定义一个名字空间前缀和使用模板匹配

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0" xmlns:eml="http://www.eagleinvsys.com/2011/EagleML-2-0"> 
    <xsl:output method="xml" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" /> 

    <xsl:strip-space elements="*" /> 

    <xsl:template match="node()|@*"> 
    <xsl:copy> 
     <xsl:apply-templates select="node()|@*"/> 
    </xsl:copy> 
    </xsl:template> 

    <xsl:template match="eml:referenceTransaction[eml:rating/eml:effectiveDate='' or not(starts-with(eml:rating/eml:ratingDataModel/eml:ratingChar1,'WL'))]"/> 
</xsl:transform>

答

试试这个

<?xml version="1.0" encoding="UTF-8" ?> 
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    xmlns:a="http://www.eagleinvsys.com/2011/EagleML-2-0" 
    version="2.0"> 
    <xsl:output method="xml" doctype-public="XSLT-compat" omit-xml-declaration="yes" encoding="UTF-8" indent="yes" /> 


    <xsl:template match="node()|@*"> 
     <xsl:copy> 
      <xsl:apply-templates select="node()|@*"/> 
     </xsl:copy> 
    </xsl:template> 

    <xsl:template match="a:referenceTransaction[normalize-space(descendant::a:effectiveDate)='' and starts-with(descendant::a:ratingChar1, 'WL')]"/> 

</xsl:transform>
