java - How to get element's value from XML using SAX parser in startElement? -

is possible content of element xml file in startelement function override function of sax handler?

below specification.

1) xml file

<employees>    <employee id="111">       <firstname>rakesh</firstname>       <lastname>mishra</lastname>       <location>bangalore</location>    </employee>    <employee id="112">       <firstname>john</firstname>       <lastname>davis</lastname>       <location>chennai</location>    </employee>    <employee id="113">       <firstname>rajesh</firstname>       <lastname>sharma</lastname>       <location>pune</location>    </employee> </employees> 

2) startelement function

@override public void startelement(string uri, string localname, string qname, attributes attributes) throws saxexception {     .......code in here.......... } 

3) expected result

element name   : employee attribute name : id attribute value: 111 firstname      : rakesh lastname       : mishra location       : bangalore  element name   : employee attribute name : id attribute value: 112 firstname      : john lastname       : davis location       : chennai  element name   : employee attribute name : id attribute value: 113 firstname      : rajesh lastname       : sharma location       : pune 

you can element's name in startelement , endelement. can attributes in startelement. values should in characters.

here very basic example on how value of element using contenthandler:

public class yourhandler extends defaulthandler {      boolean infirstnameelement = false;      public class startelement(....) {         if(qname.equals("firstname") {             infirstnameelement = true;         }     }      public class endelement(....) {         if(qname.equals("firstname") {             infirstnameelement = false;         }     }      public class characters(....) {         if(infirstnameelement) {             // characters in <firstname> element         }     } } 

if have simple example, setting boolean flags each tag ok. if have more complex scenario, might prefer store flags in map using element names keys, or create 1 or more employee classes mapped xml, instantiate them every time <employee> found in startelement, populate properties, , add collection in endelement.

here complete contenthandler example works example file. hope helps started:

public class simplehandler extends defaulthandler {      class employee {         public string firstname;         public string lastname;         public string location;         public map<string, string> attributes = new hashmap<>();     }     boolean isfirstname, islastname, islocation;     employee currentemployee;     list<employee> employees = new arraylist<>();      @override     public void startelement(string uri, string localname, string qname,             attributes atts) throws saxexception {         if(qname.equals("employee")) {             currentemployee = new employee();             for(int = 0; < atts.getlength(); i++) {                 currentemployee.attributes.put(atts.getqname(i),atts.getvalue(i));             }         }         if(qname.equals("firstname")) { isfirstname = true; }         if(qname.equals("lastname"))  { islastname = true;  }         if(qname.equals("location"))  { islocation = true;  }     }      @override     public void endelement(string uri, string localname, string qname)             throws saxexception {         if(qname.equals("employee")) {             employees.add(currentemployee);             currentemployee = null;         }         if(qname.equals("firstname")) { isfirstname = false; }         if(qname.equals("lastname"))  { islastname = false;  }         if(qname.equals("location"))  { islocation = false;  }     }      @override     public void characters(char[] ch, int start, int length) throws saxexception {         if (isfirstname) {             currentemployee.firstname = new string(ch, start, length);         }         if (islastname) {             currentemployee.lastname = new string(ch, start, length);         }         if (islocation) {             currentemployee.location = new string(ch, start, length);         }     }      @override     public void enddocument() throws saxexception {         for(employee e: employees) {             system.out.println("employee id: " + e.attributes.get("id"));             system.out.println("  first name: " + e.firstname);             system.out.println("  last name: " + e.lastname);             system.out.println("  location: " + e.location);         }     } }
