Not able to parse inner elements of XML using DocumentBuilderFactory in Java -
i'm having response xml. i'm trying parse xml object inner details. im using documentbuilderfactory this. parent object not null, when try deepnode list elements, returning null. missing anything
here response xml
responsexml
<datapacket request-id = "1"> <header> </header> <body> <consumer_profile2> <consumer_details2> <name>david</name> <date_of_birth>1949-01-01t00:00:00+03:00</date_of_birth> <gender>001</gender> </consumer_details2> </consumer_profile2></body></datapacket> and im parsing in following way
documentbuilderfactory dbf = documentbuilderfactory.newinstance(); documentbuilder db = dbf.newdocumentbuilder(); inputsource = new inputsource(); is.setcharacterstream(new stringreader(responsexml)); // consumer details. if(doc.getdocumentelement().getelementsbytagname("consumer_details2") != null) { node consumerdetailsnode = doc.getdocumentelement().getelementsbytagname("consumer_details2").item(0); -->this coming null dateofbirth = getnameditem(consumerdetailsnode, "date_of_birth"); system.out.println("dob:"+dateofbirth); } getnameditem
private static string getnameditem(node searchresultnode, string param) { return searchresultnode.getattributes().getnameditem(param) != null ? searchresultnode.getattributes().getnameditem(param).getnodevalue() : ""; } any ideas appreciated.
the easiest way search individual elements within xml document xpath. provides search syntax similar file system notation. here solution specific problem of document:
edit: solution adopted support multiple consumer_profile2 elements. need , parse nodelist instread of 1 node
import java.io.*; import javax.xml.parsers.*; import javax.xml.xpath.*; import org.w3c.dom.*; import org.xml.sax.*; public class xpathdemo { public static void main(string[] args) { try { documentbuilderfactory factory = documentbuilderfactory.newinstance(); documentbuilder builder = factory.newdocumentbuilder(); document xmldoc = builder.parse(new inputsource(new filereader("c://temp/xx.xml"))); // selects consumer_profile2 elements no matter in document string cp2_nodes = "//consumer_profile2"; // selects first date_of_birth element somewhere under current element string dob_nodes = "//date_of_birth[1]"; // selects text child node of current element string text_node = "/child::text()"; xpath xpath = xpathfactory.newinstance().newxpath(); nodelist dob_list = (nodelist)xpath.compile(cp2_nodes + dob_nodes + text_node) .evaluate(xmldoc, xpathconstants.nodeset); (int = 0; < dob_list.getlength() ; i++) { node dob_node = dob_list.item(i); string dob_text = dob_node.getnodevalue(); system.out.println(dob_text); } } catch (exception e) { e.printstacktrace(); } } }
