Remove complete node from XML, if the child attribute does not contains specific text `WorkFlow/@name != 'UNS_SMTP_SERVICES'`

Question

In my XSLT I am checking for WorkFlow/@name = 'UNS_SMTP_SERVICES' if that is not true I want to remove the Document and if non of the Document has the value I want to remove the Partner. I could achieve it to some extent but could not get the desired output.

My input:

My XSLT:

    <xsl:output method="xml" indent="yes" media-type="text/xml" omit-xml-declaration="no" encoding="utf-8"/>

<xsl:template match="@*|node()">

    </xsl:copy>

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

</xsl:stylesheet>

My output: My XSLT is not removing Document/@name ='SNDMANASN' from Partner/@name = 'VACMCLEA'.

Answer 1

You can use these two empty templates:

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

The first removes the matching Document nodes, and the second the partner ones.
