xml creation using java -


i want iterate on xml given below:

                <annotation>                     <properties>                         <propertyvalue propertyname="field_label">label.modelseriescd</propertyvalue>                         <propertyvalue propertyname="containertype">conditioncontainer</propertyvalue>                     </properties>                 </annotation>

i trying these codes: 1)

while(currentnode.haschildnodes()){                         system.out.println(currentnode.getnextsibling());                         currentnode=currentnode.getnextsibling();                     }

2)

for (int x = 0; x < childnode.getlength(); x++) {                     node current = childnode.item(x);                     if (node.element_node == current.getnodetype()) {                         string cn = current.getnodename();                         system.out.print(cn +" = ");                         string cv = current.getnodevalue();                         system.out.print(cv+" : ");                         string ct = current.gettextcontent();                         system.out.println(ct);                     }                 }

output:

[shape: null] shapetype = null : h2 annotation = null :                                   label.modelseriescd                                 conditioncontainer

i want output tag names , tag values i.e. should display like: properties propertyvalue propertyname "field_label" value label.modelseriescd means want output tags ,attribute name, attribute values , text values. can write in xml

the method below recurse on xml tree, printing requested info:

public static void printnodetree(node n) {     // print xml element name:     system.out.println("elem: " + n.getnodename());      // print xml element attributes:     namednodemap attrs = n.getattributes();     if (attrs != null) {         (int = 0; < attrs.getlength(); i++ ) {             node attr = attrs.item(i);             system.out.println("attr: " + attr.getnodename() + " = " + attr.getnodevalue());         }     }      nodelist nodelist = n.getchildnodes();      // print xml element text value     (int = 0; < nodelist.getlength(); i++) {         node currentnode = nodelist.item(i);         if (currentnode.getnodetype() == node.text_node) {             string text = currentnode.getnodevalue();             if (text != null && text.matches("\\s+")) {                 system.out.println("text: " + text);             }         }     }      // recurse on child elements      (int = 0; < nodelist.getlength(); i++) {         node currentnode = nodelist.item(i);         if (currentnode.getnodetype() == node.element_node) {             printnodetree(currentnode);         }     } }

you can initiate traversal document root:

document doc = ... printnode(doc.getdocumentelement());

output given input:

elem: annotation elem: properties elem: propertyvalue attr: propertyname = field_label text: label.modelseriescd elem: propertyvalue attr: propertyname = containertype text: conditioncontainer
