Search and navigation in XSLT
Basically all possibilities for code-navigation are supported for named templates, variables and parameters. For example: Goto Declaration, Find Usages, Highlight Usages in File, Quick Definition Lookup, and so on.
Find Usages works for Variables and Parameters as well as named XSLT Templates. It finds all places of a certain template in all XSLT Style Sheets that are contained in the specified scope.
The plugin also supports PhpStorm Goto Symbol action. The names of templates, top-level variables and parameters are offered for that action to be able to quickly navigate to them by their name.
