I have an xml file and I need to select (not remove) an specific node with its children. I know how to remove one with its children, but not how to remove all but these.

The input xml file looks like this

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"> <soapenv:Header> <wsse:Security xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"> <wsse:UsernameToken wsu:Id="UsernameToken-8"> <wsse:Username>john</wsse:Username> <wsse:Password Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordText">password</wsse:Password> </wsse:UsernameToken> </wsse:Security> </soapenv:Header> <soapenv:Body> <seq:Request xmlns:seq="http://schemas.mycompany.com/schema_v1_0"> <seq:StoreId>6</seq:StoreId> <seq:Concept>2</seq:Concept> <seq:ProductGr> <seq:ProductGroupID>10</seq:ProductGroupID> <seq:Seq>150</seq:Seq> <seq:Update>1</seq:Update> </seq:ProductGr> </seq:Request> </soapenv:Body> </soapenv:Envelope>

and I want only to obtain the following chunk of code

 <seq:Request xmlns:seq="http://schemas.mycompany.com/schema_v1_0"> <seq:StoreId>6</seq:StoreId> <seq:Concept>2</seq:Concept> <seq:ProductGr> <seq:ProductGroupID>10</seq:ProductGroupID> <seq:Seq>150</seq:Seq> <seq:Update>1</seq:Update> </seq:ProductGr> </seq:Request>

Can you help me? In addition, the prefix of the namespace can vary, altough not the namespace itself.

Thanks for your help.

The simplest approach would be something like

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/"> <xsl:copy-of select="soap:Envelope/soap:Body/*[1]" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" /> </xsl:template> </xsl:stylesheet>

which will extract the first child element of the Body, whatever its name.

It works great, but it adds the namespace xmlns:soapenv to the node selected, like this. <seq:Request xmlns:seq="schemas.mycompany.com/schema_v1_0" xmlns:soapenv="schemas.xmlsoap.org/soap/envelope">
@ingenierocps that is correct, because that namespace declaration is in force at that point in the original tree. It doesn't do any harm to have it declared but not used.
@ingenierocps if you want to get rid of unused namespace declarations for aesthetic reasons you can do it in XSLT 2.0 by adding copy-namespaces="no" to the copy-of, but in XSLT 1.0 you need to do the copying with templates instead of using copy-of
Thank you very much. It has been really helpful. I was afraid because of the namespace. After processing this xml, I send it and it must be validated against an xsd and I thougth the namespace could mess this validation, but not at all. It has worked!!!
I hadn't seen your last comment. Thats the frosting on the cake, it really works, and now with no namespaces. Thks
