List all svn:externals recursively?

I need to move the location of a component that is referenced by many projects with an svn:external.

How can I easily find all locations that 开发者_如何学运维have an svn:external to this URI?

 svn propget svn:externals http://path/to/repos -R

lists all externals, its not filtered, suppose i could grep it if i was on a decent OS.

I used a slight variation on the other answer (apologies for partial plagiarism)...

svn propget --xml -R svn:externals https://myserver/myrepo > results.xml

and then ran the results through an XPath using something like...

//properties/target[contains(./property,'https://myserver/myrepo/mysearchpath')]/@path

This gave me a short list containing all references.

The longest part was waiting for the propget which takes literally hours on our repository. Not sure if this can be improved.
