I want the function name and body of that function from a javascript to get parsed out into a separate file. How do I do that using Java?

Question

I have the following sample code:

 <Script> var lastEntdFld ; var fldobj ; var Args ; var errormsg ; function InitJSvar(){ try { //Some texts }catch(e){} } </script>

After parsing I want the following code:

function InitJSvar(){
   try {
        //Some texts
       }catch(e){}
    }

How can I do that using Java?

Answer 1

You can achieve this by writing your own Parser for javascript and exporting the result into a new file with a filewriter. I think this would be the easiest way to do it.

Also if your script is in a HTML You can use JSOUP and manual parsing.
