Java: How i pass the string in xml and get diffrent attribute -

i have xml-string and, want result-elements messageid-,designation- , status-members it. how can that?

"null <?xml version="1.0" encoding="utf-8"?> <results>     <result>         <status>-13</status>         <messageid></messageid>         <destination>null</destination>     </result>     <result>         <status>-3</status>         <messageid></messageid>         <destination>911234567898</destination>     </result>     <result>         <status>0</status>         <messageid>146092209473920945</messageid>         <destination>917827767338</destination>     </result>     <result>         <status>0</status>         <messageid>116092209473924510</messageid>         <destination>918527593928</destination>     </result>     <result>         <status>-3</status>         <messageid></messageid>         <destination>912345234567</destination>     </result> </results>" 

please me solve problem.

first of need rid of null part @ start of string. inputstream can created rest of string (see how turn string inputstreamreader in java?). parse stream dom parser , extract messageids xpath:

string s = "null<?xml version=\"1.0\" encoding=\"utf-8\"?><results><result><status>-13</status><messageid></messageid><destination>null</destination></result><result><status>-3</status><messageid></messageid><destination>911234567898</destination></result><result><status>0</status><messageid>146092209473920945</messageid><destination>917827767338</destination></result><result><status>0</status><messageid>116092209473924510</messageid><destination>918527593928</destination></result><result><status>-3</status><messageid></messageid><destination>912345234567</destination></result></results>"; inputstream = new bytearrayinputstream(s.substring(s.indexof("<?xml")).getbytes(standardcharsets.utf_8));  documentbuilder builder = documentbuilderfactory.newinstance().newdocumentbuilder();  document document = builder.parse(is); xpath path = xpathfactory.newinstance().newxpath();  string expression = "//messageid";  nodelist list = (nodelist) path.evaluate(expression, document, xpathconstants.nodeset); list<string> messageids = new arraylist<>(list.getlength()); (int = 0, l = list.getlength(); < l; i++) {     messageids.add(list.item(i).gettextcontent()); } system.out.println(messageids);
