XSLT XML to XML Remove node if specific child not does not exist

[Ara]

I'm new to XSL, and not able to find information on this question. This is only for XSLT 1.0, and will eventually be run from XSLTproc.Here is an example XML\[code\]<root><node> <data /> <child> <grandchild /> </child> <step-child action="removenode" /></node><node> <data /> <step-child action="removenode" /></node></root>\[/code\]Basically, I want to keep everything except.remove any \[code\]<node>\[/code\] with no \[code\]<child>\[/code\]remove all \[code\]<step-child>\[/code\]I can only figure out how to remove unwanted nodes, but even that is questionable. I really appreciate any help with this.
