parsing an XML with JAVA -

i trying parse few specific parts of xml doc. looking @ pulling data out of analysis section, need warnings, errors, passes , need go each of sections () , result , result level , text example in "error" need level of error , text "error".

<document>     <configuration>     </configuration>     <data>     </data>     <analysis warnings="5" errors="3" information="0" passed="false">         <files>         </files>         <results>             <form>                 <section number="0">                     <result level="error">error</result>                     <result level="error">error</result>                     <result level="error">error</result>                     <result level="warning">warning</result>                     <result level="warning">warning</result>                 </section>                 <section number="1">                     <result level="warning">warning</result>                 </section>                 <section number="2">                     <result level="warning">warning</result>                     <result level="warning">warning</result>                 </section>             </form>         </results>     </analysis> </document> 

i have following code:

public void processxmlfrompath(string path) throws exception     {         documentbuilderfactory factory = documentbuilderfactory.newinstance();         documentbuilder builder = factory.newdocumentbuilder();         document document =  builder.parse(path);         nodelist nodelist = document.getdocumentelement().getchildnodes();          (int = 0; < nodelist.getlength(); i++) {           node node = nodelist.item(i);           if (node instanceof element) {             system.out.println(node.getattributes().tostring());             nodelist childnodes = node.getchildnodes();             (int j = 0; j < childnodes.getlength(); j++) {               node cnode = childnodes.item(j);                if (cnode instanceof element) {                   system.out.println(cnode.getnodename().tostring());                    if(cnode.getnodename().tostring() == "analysis")                   {                       string content = cnode.getlastchild().gettextcontent().trim();                       system.out.println(content);                       //i thought print children under analysis section screen mistaken. make point.                   }               }             }            }          }     } 

the thing i'm getting print console is:

configuration data analysis 

any appreciated!

a couple of issues code:

1. cnode.getnodename().tostring() == "analysis", string comparison .equals
2. analysis direct descendant of document (per xml piece have here), has checked on. code checks @ level 3 instead of 2
3. you need drill further down analysis results, form , text nodes.

edit: based on comments, efficient way traverse without multiple loops woild recursion, below:

public static void main(string[] args) throws parserconfigurationexception,         saxexception, ioexception {     inputstream path = new fileinputstream("sample.xml");     documentbuilderfactory factory = documentbuilderfactory.newinstance();     documentbuilder builder = factory.newdocumentbuilder();     document document = builder.parse(path);     traverse(document.getdocumentelement());  }  public static void traverse(node node) {     nodelist list = node.getchildnodes();     (int = 0; < list.getlength(); i++) {         node currentnode = list.item(i);         traverse(currentnode);      }      if (node.getnodename().equals("result")) {         system.out.println("this -> " + node.gettextcontent());     }  } 

this gives result as:

this -> error -> error -> error -> warning -> warning -> warning -> warning -> warning
