Efficent way to parse XML Data

[YuenLian Wu]

Hi All,

I am not too familiar with DOM API. Currently I have the following XML File,

    
<services>
- <service>
  <name>Currency Conversion Service</name> 
  <wsdl>http://cis.unisa.edu.au/~cisrkt/ect/currency.wsdl</wsdl> 
  </service>
- <service>
  <name>Stock Quote Service</name> 
  <wsdl>http://cis.unisa.edu.au/~cisrkt/ect/stock.wsdl</wsdl> 
  </service>
- <service>
  <name>Another CC Service</name> 
  <wsdl>http://cis.unisa.edu.au/~cisrkt/ect/currency.wsdl</wsdl> 
  </service>
</services>

And My Java Code to parse it will be:

   
Document doc = parseRemoteXMLFile(path);

NodeList nl = doc.getElementsByTagName("service");

HashMap configMap = new HashMap();

for ( int i = 0; i < nl.getLength(); i++ ) {
//Get Name
System.out.println(nl.item(i).getChildNodes().item(1).getChildNodes().item(0).getNodeValue());
//Get WSDL 
                        System.out.println(nl.item(i).getChildNodes().item(3).getChildNodes().item(0).getNodeValue());
}
 
 

My Code seems not too efficient as it's kind of hard code.
My ideal wish will be getting values dynamically, please teach me how


Myriads of Thanks

XPATH provides an API with a more compact and elegant notation.

However, as I found out in this article, it is much slower than the direct manipulation of the DOM as in your example. That the tradeoff
