Delete attribute
The Delete Attribute refactoring allows you to delete all attributes matching the selected attribute name on tags with the selected tag name. This bulk removal of attributes may be useful as XML schemas evolve.
Delete an attribute
Place the caret at the attribute to delete, press Ctrl+Alt+Shift+T, and then select Delete Attribute from the list.
In the dialog that opens, specify the scope to delete the attribute 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 attribute 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.
