使用XSLT删除具有相同名称的XML层次结构元素?

标签: xml xslt xslt-1.0

我得到的 XML 响应在响应中具有彼此相邻的相同命名元素,这导致了我的问题,我需要使用 XSLT 1.0 删除此重复元素>。响应中有问题的元素是<RoundIncidents>。我浏览了其他问题,但找不到将响应转换为正确格式所需的内容。

带有重复元素的XML响应

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soap:Body>
      <GetSiteIncidentsResponse xmlns="http://webservices.whitespacews.com/">
         <GetSiteIncidentsResult>
            <ErrorCode>0</ErrorCode>
            <ErrorDescription>Success</ErrorDescription>
            <SuccessFlag>true</SuccessFlag>
            <RoundIncidents>
               <RoundIncidents>
                  <ExtensionData />
                  <AccountSiteID>0</AccountSiteID>
                  <RoundIncidentID>8</RoundIncidentID>
                  <RoundRoundAreaServiceScheduleID>157</RoundRoundAreaServiceScheduleID>
                  <RoundCode>REC1</RoundCode>
                  <ScheduleName>MonFort2</ScheduleName>
                  <ServiceName>Recycling Collection Service</ServiceName>
                  <RoundAreaName>REC1 - MonFort2</RoundAreaName>
                  <RoundIncidentDate>2019-04-08T16:12:10</RoundIncidentDate>
                  <RoundIncidentNotes>Road Closed</RoundIncidentNotes>
                  <RoundIncidentCreatedByID>129</RoundIncidentCreatedByID>
                  <RoundIncidentCreatedDate>2019-04-08T16:12:26.493</RoundIncidentCreatedDate>
               </RoundIncidents>
            </RoundIncidents>
         </GetSiteIncidentsResult>
      </GetSiteIncidentsResponse>
   </soap:Body>
</soap:Envelope>

遣散孩子

将模板添加到identity transform中,以匹配子元素,其中 父级和子级具有相同的QName,并且该子级被绕过:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*[name() = name(..)]">
    <xsl:apply-templates select="node()"/>
  </xsl:template>

</xsl:stylesheet>

Demo上Martin Honnen方便的XSLT小提琴。

请注意,以上按词法比较QName,其中可能包含名称空间前缀。要正确地比较名称( ),请检查名称空间URI:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="*[    local-name() = local-name(..) 
                         and namespace-uri() = namespace-uri(..)]">
    <xsl:apply-templates select="node()"/>
  </xsl:template>

</xsl:stylesheet>

搬走父母

每个OP的更新请求,这是在子元素名为同名元素时删除父元素的方法。在选择采用哪种方法时,请考虑一个孩子通常只能有一个父母,但一个父母可以有多个孩子。

简单QName check

<xsl:template match="*[*[name() = name(..)]]">
  <xsl:apply-templates select="node()"/>
</xsl:template>

完整的命名空间URI check

<xsl:template match="*[*[    local-name() = local-name(..) 
                         and namespace-uri() = namespace-uri(..)]]">
  <xsl:apply-templates select="node()"/>
</xsl:template>
