Wrap tag
The Wrap Tag refactoring allows you to enclose all tags with the name of the selected tag in newly generated parent tags. This bulk wrapping of tags may be useful as XML schemas evolve.
Wrap a tag
Place the caret at the tag to wrap, press Ctrl+Alt+Shift+T, and then select Wrap Tag from the list.
In the dialog that opens, type the name of the parent tag to create and specify the scope to wrap the tag in.
With the Directory scope specified, select the Recursively checkbox to include sub-directories.
Select the Limit to files with DTD:... checkbox to limit the scope to the files with the same
DOCTYPEas specified for the current file.

Invoke the refactoring:
Click OK to continue immediately or click Preview to have WebStorm show the usages of the selected tag in the Find tool window where you can mark usages as included in or excluded from refactoring.
Click Show XSLT... to view a fragment of the XSLT that is equivalent to the requested refactoring. This fragment can be used by XSLT processors to perform the requested refactoring on files outside your WebStorm project.
