基于节点值的 XSL 过滤元素

Question

我似乎无法弄清楚如何才能成功实现这个基本的 xsl。我想用 SalesOrderStatus 值 <> SalesOrder 过滤掉 xml 中的所有 SalesLines 元素（不要保留 Sent / CancelledBySales）。

到目前为止我创建的 XSL：

<!-- Michael van den Dool 18-10-2019 17:46 filter saleslines  -->
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

    xmlns:xs="http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder" exclude-result-prefixes="xs" version="2.0">

    <!-- Copy everything -->

    <xsl:template match="node() | @*">

        <xsl:copy>

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

        </xsl:copy>

    </xsl:template>



    <!-- Match elements which need to be filtered and do not copy them to the output -->

    <xsl:template match="SalesTable/SalesLine[not(SalesTable/SalesLine/SalesOrderStatus/text() = 'SalesOrder')]"/>

</xsl:stylesheet>

当运行 xsl 没有被过滤掉。我认为它在某个名称空间/层次结构中。但我还是xsl的业余爱好者，抱歉..

Answer 1

这是一个简单、简短的 XSLT 1.0 解决方案。

您的主要问题是未能在匹配模式中指定元素的名称空间 -- 它们不在 "no namespace"

中

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:x="http://schemas.microsoft.com/dynamics/2008/01/documents/SalesOrder">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

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

  <xsl:template match="x:SalesLine[not(x:SalesOrderStatus = 'SalesOrder')]"/>
</xsl:stylesheet>
