Replace tag with attribute
The Replace Tag with Attribute refactoring allows you to replace sub-tags definitions on a set of XMLs tag with equivalent attributes. If this refactoring is invoked, all tags matching the selected tag's name on tags with the selected parent tag name may be removed, and equivalent attributes created. This bulk transformation of sub-tags to attributes is useful as XML schemas evolve.
Converting a tag into an attribute
Pressing Preview opens the Refactoring preview window displaying all found usages of the tags to be replaced. In this window you can exclude/include usages you want to refactor.
Pressing Show XSLT... opens the XSLT preview window displaying a small fragment of XSLT equivalent to the refactoring requested. This fragment can be used by XSLT processors to perform the requested refactoring on files external to your WebStorm project.
The preview window may appear anyway if the files that you want to change are read-only.
In the editor, place the caret within the tag to be converted.
Selectfrom the main or the context menu.
Determine the name of the attributes to replace the selected tags.
Determine the scope of the replacement. All tags matching the name of the tag selected on the parent tag selected will be replaced if they are in the selected scope. Scopes available include the current file, the entire project, or a specified directory or module. Directory scopes can either include sub-directories, or not, based on whether the Recursively checkbox is selected. If the Limit to files with DTD:... checkbox is selected, the scope will be limited to those files with the same DOCTYPE as the current file.
