Cannot run Xpath queries from JAVA in XML files having <DOCTYPE> tag -

-

i have made following method runs hard-coded xpath queries in hard-coded xml file. method works perfect 1 exception. xml files contains following tag

           <!doctype workflowdefinition system "wfdef4.dtd">

when try run query in file following exception:

     java.io.filenotfoundexception:       c:\programfiles\code\other\xpath\wfdef4.dtd(the system cannot find file specified).

the question : what can instruct program not take under consideration dtd file? have noted path c:\programfiles\code\other\xpath\wfdef4.dtd 1 run application , not 1 actual xml file located.

thank in advace

here method:

 public string evaluate(string expression,file file){   xpathfactory factory = xpathfactory.newinstance();   xpath = xpathfactory.newinstance().newxpath();   stringbuffer strbuffer = new stringbuffer();   try{     inputsource inputsource = new inputsource(new fileinputstream(file));                          //evaluates expression     nodelist nodelist = (nodelist)xpath.evaluate(expression,                     inputsource,xpathconstants.nodeset);                           //does other stuff, irrelevant question.     (int = 0 ; <nodelist.getlength(); i++){      strbuffer.append(nodelist.item(i).gettextcontent());     }   }catch (exception e) {    e.printstacktrace();   }   return strbuffer.tostring();       }

and answer :

    xpath = xpathfactory.newinstance().newxpath();     documentbuilderfactory dbf = documentbuilderfactory.newinstance();     //add line ignore dth dtd     dbf.setfeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);
