如果子属性不包含特定文本 `WorkFlow/@name != 'UNS_SMTP_SERVICES'`，则从 XML 中删除完整节点答案

【问题标题】：Remove complete node from XML, if the child attribute does not contains specific text `WorkFlow/@name != 'UNS_SMTP_SERVICES'`如果子属性不包含特定文本 `WorkFlow/@name != 'UNS_SMTP_SERVICES'`，则从 XML 中删除完整节点

【问题描述】：

在我的 XSLT 中，我正在检查 WorkFlow/@name = 'UNS_SMTP_SERVICES'，如果不是这样，我想删除 Document，如果没有 Document 具有我想删除 Partner 的值。我可以在一定程度上实现它，但无法获得所需的输出。

我的意见：

我的 XSLT：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <!-- <xsl:strip-space elements="*"/> -->
    <xsl:output method="xml" indent="yes" media-type="text/xml" omit-xml-declaration="no" encoding="utf-8"/>
    <xsl:param name="lineDelimiter" select="'&#10;'"/>
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="Partner[not(.//WorkFlow[not(@name!='UNS_SMTP_SERVICES')])]" />

</xsl:stylesheet>

我的输出：我的 XSLT 没有从 Partner/@name = 'VACMCLEA' 中删除 Document/@name ='SNDMANASN'。

标签： xml loops xslt edi

【解决方案1】：

您可以使用这两个空模板：

<xsl:template match="Document[not(BusinessProcess/WorkFlow[@name='UNS_SMTP_SERVICES'])]" />
<xsl:template match="Partner[not(Documents/Document/BusinessProcess/WorkFlow[@name='UNS_SMTP_SERVICES'])]" />

第一个删除匹配的Document 节点，第二个删除partner 的节点。
