我需要执行xslt将此xml转换为另一个WHERE：仅显示 effectiveDate 不为空且 ratingChar1 以“WL”开头  我真的不明白我在做什么，但这里是我的xslt： 我需要做xslt将这个xml转换为另一个WHERE：仅显示 effectiveDate 不为空， ratingChar1 以“WL”开头  我真的不明白我在做什么，但这里是我的xslt：

如果您要排除某些referenceTransaction元素，则确实需要一个与referenceTransaction匹配的模板，条件为[]。在条件方面，你应该颠倒逻辑。你应该否定它以给出你想要删除的条件，而不是满足你想要保留的条件。

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

即如果referenceTransaction为空或effectiveDate不以ratingChar1开头，请删除WL。

然而，你有第二个问题。在您的XML中，您有默认命名空间

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

但是你没有在XSLT中考虑到这一点。如果您确实在使用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，如果您使用的是XSLT 1.0，则必须定义名称空间前缀并在模板匹配中使用

<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>

答案 1 :(得分：0)

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>
