Question

我在xml中有edi doc看起来像这样（这只是一个片段，实际的EDI在这篇文章的末尾）

<ediroot>
<interchange><sender><address Id="7817942742" Qual="12" /></sender>
<group>
    <transaction Control="0001">
            <segment Id="B3">
                <element Id="B302">12345678</element>
                <element Id="B303">NS</element>
                <element Id="B304">CC</element>
                <element Id="B305">L</element>
            </segment>
            <segment Id="G62">
                <element Id="G6201">12</element>
                <element Id="G6202">20160928</element>
            </segment>
            <segment Id="R3">
                <element Id="R301">ABCD</element>
                <element Id="R302">B</element>
            </segment>
        </transaction>
        <transaction Control="0002">
            <segment Id="B3">
                <element Id="B302">999999</element>
                <element Id="B303">NS</element>
                <element Id="B304">CC</element>
            </segment>
            <segment Id="G62">
                <element Id="G6201">13</element>
                <element Id="G6202">20150928</element>
            </segment>
            <segment Id="R3">
                <element Id="R301">ABCD</element>
                <element Id="R302">B</element>
            </segment>
        </transaction>
    </group>
</interchange>
</ediroot>

我需要将元素Id设置为新元素，将元素值设置为值，如此

<ediroot>
<interchange>
<group>
    <transaction Control="0001">
            <B3>
                <B302>12345678</B302>
                <B303>NS</B303>
.....

我正在通过群体进行迭代，我正在使用这个xslt

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="ediroot">
<ediroot>
    <xsl:apply-templates select="interchange"/>
</ediroot>
</xsl:template>
    <xsl:template match="group">
        <transaction> 
            <xsl:apply-templates select="transaction"/>
        </transaction>
    </xsl:template>
            <xsl:template match="transaction">
            <txn>
                <xsl:for-each-group select="segment" group-by="@Id">
                    <group name="{current-grouping-key()}">
                        <Id><xsl:value-of select="element/@Id"/></Id>
                        <Value><xsl:value-of select="element"/></Value>
                    </group>
                </xsl:for-each-group>
            </txn>
            </xsl:template>

</xsl:stylesheet>

它会生成像这样的xml

<?xml version="1.0" encoding="UTF-8"?>
<ediroot>
   <transaction>
      <txn>
        <group name="B3">
            <Id>B302 B303 B304 B305</Id>
            <Value>12345678 NS CC L</Value>
        </group>

        <group name="G62">
            <Id>G6201 G6202</Id>
            <Value>86 20160928</Value>
        </group>
        <group name="R3">
            <Id>R301 R302</Id>
            <Value>ABCD B</Value>
        </group>
      </txn>
      <txn>
         <!-- second txn group -->
      </txn>
   </transaction>
</ediroot>

如何将group / transaction / segment / element作为单独的xml元素而不是一个节点？即而不是这个

<group name="B3">
            <Id>B302 B303 B304 B305</Id>
            <Value>12345678 NS CC L</Value>
        </group>

I need this

            <B3>
                <B302>12345678</B302>
                <B303>NS</B303>
                <B304>CC</B304>
                <B305>L</B305>

对于有兴趣查看实际xml的人，使用http://edireader.sourceforge.net/进行edi-to-xml转换

Answer 1

您提供的XML包含语法错误：它包含第二个<group>开始标记，其中需要结束标记。

虽然XSLT支持迭代，但通常有更简单的方法。你的似乎就是这种情况。您希望将具有Id属性的每个元素转换为另一个元素，这似乎需要一个带有适当选择器的简单模板，仅此而已。例如：

<xsl:stylesheet version="1.0"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

   <!-- identity transform for otherwise-unmatched nodes and attributes -->
   <xsl:template match="@*|node()">
     <xsl:copy>
       <xsl:apply-templates select="@*|node()" />
     </xsl:copy>
   </xsl:template>

   <!-- Special handling for elements bearing an Id attribute -->
   <xsl:template match="segment[@Id]|element[@Id]">
     <!-- transform as an element whose name is drawn from the Id attribute -->
     <xsl:element name="{@Id}">
       <!-- transform child nodes (including text nodes), but not attributes -->
       <xsl:apply-templates select="node()" />
     </xsl:element>
   </xsl:template>

</xsl:stylesheet>

Answer 2

我不明白你的榜样。通常，您可以使用

<xsl:for-each select="current-group()">

或：

<xsl:apply-templates select="current-group()"/>

处理当前组的成员。

工作示例：http://xsltransform.net/jz1PuP9

使用xslt显示包含组的嵌套元素
