【中文标题】XSLT 循环遍历具有针对模式的属性的元素【英文标题】：XSLT loop through element with attritbute against a schema 【发布时间】：2020-01-20 00:29:47 【问题描述】：您好，我对 xml 转换还很陌生。我有一个 delima，我试图循环遍历具有属性和子元素的元素。我正在使用现有文件，即引用模式。我已经尝试了几种不同的循环方式，基于我可以从其他 cmets 收集到的内容，但仍然要么丢弃部分元素，要么根本不显示 输入样本
<PropertyDetail>
<parkingType>Surface Lot</parkingType>
<parkingSpaces>25</parkingSpaces>
<parkingAssignmentAvailable>true</parkingAssignmentAvailable>
<parkingAssignedFee>false</parkingAssignedFee>
<parkingSpaceFee></parkingSpaceFee>
<parkingComment>parking Comments</parkingComment>
<parkingType>Garage Lot</parkingType>
<parkingSpaces>12</parkingSpaces>
<parkingAssignmentAvailable>true</parkingAssignmentAvailable>

【问题讨论】：
架构似乎是所需的输出 - 不确定它与手头的问题有多相关。另请注意，您的输入不是格式正确的 XML：<PropertyDetail> 与 </propertyDetail> 不匹配。
【参考方案1】：
AFAICT，你想做的事：
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:template match="/propertyDetail">
<Information>
<xsl:for-each-group select="*" group-starting-with="parkingType">
<Parking ParkingType=".">
<xsl:apply-templates select="current-group() except ."/>
</Parking>
</xsl:for-each-group>
</Information>
</xsl:template>
<xsl:template match="parkingAssignmentAvailable">
<Assigned>
<xsl:value-of select="."/>
</Assigned>
</xsl:template>
<xsl:template match="parkingAssignedFee">
<AssignedFee>
<xsl:choose>
<xsl:when test=".='true'">Paid</xsl:when>
<xsl:when test=".='false'">Free</xsl:when>
</xsl:choose>
</AssignedFee>

【讨论】：
感谢您的回复。不幸的是，我提供的 sn-p 只是较大样式表的一部分，它已经有一个***模板。当我使用您提供的内容更新该部分时，我收到以下错误“元素 xsl:template 必须是***的（xsl:stylesheet、xsl:transform 或 xsl:package 的子级）” 可以改用命名模板吗？ 所有模板都必须是***的。如果没有看到整个图片，恐怕我无法为您提供帮助 - 请参阅：minimal reproducible example。 @Frank，如果您使用xsl:template match="propertyDetail" 而不是xsl:template match="/propertyDetail"，Michael 的代码对于任何级别的propertyDetail 元素都可以正常工作。放弃“循环”的想法，并使用带有不同模板的推送样式处理，其余代码使用apply-templates，Michael 的建议将适合任何更大的上下文。
将此代码与现有代码集成的最佳方式可能是采用管道的形式：第一步是将平面结构分组以反映内在层次结构，下一步是处理该层次结构结构。以上是关于XSLT 循环遍历具有针对模式的属性的元素的主要内容，如果未能解决你的问题，请参考以下文章
