Delete attribute
The Delete Attribute refactoring allows you to delete a set of attribute definitions on a set of XML tag. If this refactoring is invoked, all attributes matching the selected attribute name on tags with the selected tag name may be removed. This bulk removal of attributes may be useful as XML schemas evolve.
Deleting an attribute
In the editor, place the caret within the attribute to be deleted.
Select from the main or the context menu.
Determine the scope of the deletion. All attributes matching the name of the attribute selected on the tag selected will be deleted 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.
Click Preview button to make WebStorm to search for usages of the selected attribute Find window.
Click OK to continue. If you do not select the Preview option, all usages will be changed immediately.
Note the following:
Pressing Preview opens the Refactoring preview window displaying all found usages of the attributes to be removed. 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 Refactoring preview window may appear anyway, if the files to be affected are read-only.
