Question

交付文档xml包含两个<SourceDocument>标记：

<SourceDocument type="order">

和

<SourceDocument type="desadv">

我尝试使用

从<SourceDocument type="order">中提取订单号

    <xsl:element name="tellimus">
        <xsl:value-of select="../../RefInfo/SourceDocument/SourceDocumentNum"/>
    </xsl:element>

但生成的xml文件中的tellimus元素为空。如何从<SourceDocument type="order">到<tellimus>元素提取订单号？

XSL：

<?xml version="1.0" encoding="ISO-8859-1" standalone="no" ?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" standalone="yes"/>

    <xsl:template match="/">
        <xsl:element name="VFPData">

        </xsl:element>
    </xsl:template>

    <!-- this will denormalize XML data -->
    <xsl:template match="/E-Document/Document/DocumentItem/*">

两点：

您的路径中缺少DocumentInfo个节点
最好专门定位order元素，而不是依赖于隐式节点集字符串转换

使用以下表达式：

../../DocumentInfo/RefInfo/SourceDocument[@type='order']/SourceDocumentNum

仅进行该更改会产生以下输出（格式化）：

<VFPData>
   <Document-Order>
      <tellimus>OR51500044007</tellimus>
   </Document-Order>
</VFPData>
