【中文标题】我需要更多帮助来遍历 XML 文档【英文标题】：I need more help traversing an XML document 【发布时间】：2021-12-18 00:58:15 【问题描述】：我最近写了一些代码来使用<xsl:for-each select="//dfor:children/dfor:child">遍历XML
此代码运行良好，但我知道需要遍历相同的子元素但来自指定的父元素，因为现在有多个子集 - 它们的父名称为“otom_businessPartner”和“otom_expense”，因为迭代结果适用于两个子套，而不是我需要的一套。
这是 XML：
<?xml version="1.0" encoding="UTF-8"?>
<dfor:form-data xmlns:dfor="http://kana.com/dforms">
<dfor:field>
<dfor:name>otom_businessPartner</dfor:name>
<dfor:children>
<dfor:child>
<dfor:field>
<dfor:name>txt_bpName</dfor:name>
<dfor:value>Southampton City Council</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>txt_bpRelationship</dfor:name>
<dfor:value>Southampton City Council</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>txt_bpShare</dfor:name>
<dfor:value>Southampton City Council</dfor:value>
</dfor:field>
</dfor:child>
<dfor:child>
<dfor:field>
<dfor:name>txt_bpName</dfor:name>
<dfor:value>222222222</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>txt_bpRelationship</dfor:name>
<dfor:value>222222222</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>txt_bpShare</dfor:name>
<dfor:value>2222222222222222</dfor:value>
</dfor:field>
</dfor:child>
</dfor:children>
</dfor:field>
<dfor:field>
<dfor:name>otom_expenses</dfor:name>
<dfor:children>
<dfor:child>
<dfor:field>
<dfor:name>sel_expense</dfor:name>
<dfor:value>Advertising</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>txt_other2</dfor:name>
<dfor:value/>
</dfor:field>
<dfor:field>
<dfor:name>num_actual</dfor:name>
<dfor:value>100</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>num_private</dfor:name>
<dfor:value>100</dfor:value>
</dfor:field>
</dfor:child>
<dfor:child>
<dfor:field>
<dfor:name>sel_expense</dfor:name>
<dfor:value>Leasing charges</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>txt_other2</dfor:name>
<dfor:value>car</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>num_actual</dfor:name>
<dfor:value>200</dfor:value>
</dfor:field>
<dfor:field>
<dfor:name>num_private</dfor:name>
<dfor:value>100</dfor:value>
</dfor:field>
</dfor:child>
</dfor:children>
</dfor:field>
</dfor:form-data>
这是 XLST：
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:dfor="http://kana.com/dforms" exclude-result-prefixes="dfor">
<xsl:param name="name" />
<xsl:param name="ref" />
<xsl:template match="/">
<html>
<body>
<p><strong>SECTION TITLE</strong></p>
<xsl:for-each select="//dfor:child">
<h4>Business partner <xsl:value-of select="position()" />:</h4>
<ul>
<xsl:for-each select="dfor:field">
<!-- Business Partner's name -->
<xsl:if test="dfor:name='txt_bpName'">
<li><strong>Business Partner's name: </strong> <xsl:value-of select="dfor:value"/></li>
</xsl:if>
<!-- Business Partner's relationship -->
<xsl:if test="dfor:name='txt_bpRelationship'">
<li><strong>Business Partner's relationship: </strong> <xsl:value-of select="dfor:value"/></li>
</xsl:if>
<!-- Share of profits -->
<xsl:if test="dfor:name='txt_bpShare'">
<li><strong>Share of profits: </strong> <xsl:value-of select="dfor:value"/></li>
</xsl:if>
</xsl:for-each>
</ul>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
它返回所有 4 个孩子（2 个来自 otom_businessPartners，2 个来自 otom_expense）我需要找出正确的遍历备份“otom_businessPartners”和“otom_expense”，以仅退休我想要的两个。
这是需要工作的行。

【问题讨论】：
【参考方案1】：由于您没有发布预期的结果，我主要是在这里猜测。看来您想做类似（简化示例）的事情：
XSLT 1.0
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:dfor="http://kana.com/dforms"
exclude-result-prefixes="dfor">
<xsl:template match="/dfor:form-data">
<html>
<body>
<xsl:for-each select="dfor:field[dfor:name='otom_businessPartner']/dfor:children/dfor:child">
<h4>
<xsl:text>Business partner </xsl:text>
<xsl:value-of select="position()" />
<xsl:text>:</xsl:text>
</h4>
<ul>
<!-- Business Partner's name -->
<li>
<strong>Business Partner's name: </strong>
<xsl:value-of select="dfor:field[dfor:name='txt_bpName']/dfor:value"/>
</li>
<!-- more here -->
</ul>
</xsl:for-each>
</body>
</html>
</xsl:template>
</xsl:stylesheet>
应用于您的输入示例，这将返回：
结果
<html>
<body>
<h4>Business partner 1:</h4>
<ul>
<li><strong>Business Partner's name: </strong>Southampton City Council
</li>
</ul>
<h4>Business partner 2:</h4>
<ul>
<li><strong>Business Partner's name: </strong>222222222
</li>
</ul>
</body>
</html>
