i want retrieve string ih2bj24l46bkgt558qsef04jeq under identifier statepoolid script section. how find script in html , string using casperjs?

accessing window.sawxmlislandidclientstatexml:

this script element in page adds variable global scope, can access through casper.evaluate:

casper.then(function(){     var sawxmlislandidclientstatexml = casper.evaluate(function(){         return window.sawxmlislandidclientstatexml;     });     // todo: });

doing sawxmlislandidclientstatexml:

you could

  • do simple string operations split string in more manageable pieces can parsed easier yourself,
  • write regex matcher find specific detail you're looking for, or
  • use domparser parse string xml , use either yourparseddocument.queryselector or yourparseddocument.evaluate locate element through css selectors or xpath expressions, respectively.
