how to find the Strings which are hard-coded in xHtmls

Question

how to find the Strings which are hard-coded in xHtmls and java code base. The purpose is to externalize them as part of localization. I mean they are not in a particular pattern to use regex to find them. is there a third party tool which can automate? or do I have to do it manually? example for hard-coded string: if the text is in the form of:

<xyz:param
     name = "cat"
     value = "meow"> 

here the string "meow" is hard coded. But if its defined in prop.file and used in the form of

 <xyz:param
     name = "cat"
     value = "#{msgXYZ['msg.services.cat.meow']}"> 

then its externalized. All good.
