使用给定的XML实现嵌套/层次结构

标签： xml xslt-1.0

这是我的一些xml数据，一个相当扁平的结构，itemMapCode = 1 / itemValue = * values，标记我们拥有的数据类型。 M =主要部分，C =类别，W =要嵌套在类别中的工作代码，H代表标题。

<?xml version="1.0" encoding="UTF-8"?>

我有的XSL（在这个论坛的帮助下派生！）可以正常使用M部分和嵌套的C / W部分，但是我遇到了H / header部分的问题。我尝试使用generateKey方法，就像我用于C和W一样，但如果我用M / H尝试它，它就不起作用。 

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" />
<xsl:strip-space elements="*" />

<xsl:key name="kWork" match="faRecord[item[itemMapCode = 1]/itemValue = 'W']" use="
generate-id(preceding-sibling::faRecord[item[itemMapCode = 1]/itemValue = 'C'][1])
" />

<xsl:template match="EstimateDisplayRequest">
<MCSResponse>
  <EstimateDisplayResponse>
    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'M']" />
    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'C']" />

    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'H']" />
    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'F']" />
  </EstimateDisplayResponse>
</MCSResponse>
</xsl:template>

<xsl:template match="faRecord[item[itemMapCode = 1]/itemValue = 'M']">
<EstimateDetail>
  <xsl:apply-templates select="item" />
</EstimateDetail>
</xsl:template>

<xsl:template match="faRecord[item[itemMapCode = 1]/itemValue = 'C']">

  <xsl:apply-templates select="item" />      
  <xsl:apply-templates select="key('kWork', generate-id())" />
</CategoryDetail>
</xsl:template>

<xsl:template match="faRecord[item[itemMapCode = 1]/itemValue = 'W']">
<WorkcodeDetail>
  <xsl:apply-templates select="item" />      
</WorkcodeDetail>
</xsl:template>

<xsl:template match="faRecord[item[itemMapCode = 1]/itemValue = 'H']">
<EstimateHeader>
  <xsl:apply-templates select="item" />
</EstimateHeader>
</xsl:template>

<!-- this catches <recordCode> and unknown elements -->
<xsl:template match="faRecord/recordCode" />
<xsl:template match="faRecord/item[itemMapCode=1]" />

<xsl:template match="faRecord/item[itemMapCode!=1]">
<xsl:variable name="elemName">

    <xsl:when test="itemMapCode = 2">SortKey</xsl:when>

    <xsl:when test="itemMapCode = 41">WorkcodeCategory</xsl:when>
    <xsl:when test="itemMapCode = 42">Workcode</xsl:when>

    <xsl:when test="itemMapCode = 80">CategoryCode</xsl:when>
    <xsl:when test="itemMapCode = 81">CategoryName</xsl:when>

    <xsl:when test="itemMapCode = 90">HeaderText</xsl:when>

  </xsl:choose>
</xsl:variable>

<xsl:if test="$elemName != ''">
  <xsl:element name="{$elemName}">         
    <xsl:value-of select="./itemValue" />
  </xsl:element>
</xsl:if>
<xsl:if test="$elemName = '' and itemMapCode != 1">
  <xsl:message>Warning: no mapping for itemMapCode '<xsl:value-of select="itemMapCode" />'</xsl:message>
</xsl:if>
</xsl:template>
</xsl:stylesheet>

我想要的输出是 - 

<EstimateHeader>
  <HeaderText>xxxxxx</HeaderText>
  <HeaderText>yyyy</HeaderText>
</EstimateHeader>

作为替代方案，可以将HeaderText项合并到一个HeaderText标记中吗？

<EstimateHeader>
  <HeaderText>xxxxxx yyyy</HeaderText>
</EstimateHeader>

TIA！

最小化示例在这里会更有用。

尝试更改此内容：

<xsl:template match="EstimateDisplayRequest">
<MCSResponse>
  <EstimateDisplayResponse>
    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'M']" />
    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'C']" />

    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'H']" />
    <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'F']" />
  </EstimateDisplayResponse>
</MCSResponse>
</xsl:template>

进入这个：

<xsl:template match="EstimateDisplayRequest">
    <MCSResponse>
        <EstimateDisplayResponse>
            <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'M']" />
            <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'C']" />
            <EstimateHeader>
                <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'H']" />
            </EstimateHeader>
            <xsl:apply-templates select="*/faRecord[item[itemMapCode = 1]/itemValue = 'F']" />
        </EstimateDisplayResponse>
    </MCSResponse>
</xsl:template>

和此：

<xsl:template match="faRecord[item[itemMapCode = 1]/itemValue = 'H']">
<EstimateHeader>
  <xsl:apply-templates select="item" />
</EstimateHeader>
</xsl:template>

进入这个：

<xsl:template match="faRecord[item[itemMapCode = 1]/itemValue = 'H']">
    <xsl:apply-templates select="item" />
</xsl:template>
