Read element from XML

You need an XML parser. You can either go with a
low-level parser such as Xerces or Crimson
(<a href=http://xml.apache.org/ target=new>http://xml.apache.org/</a>) or
something a little bit higher level such as
JDOM (<a href=http://www.jdom.org/ target=new>http://www.jdom.org/</a>) or Dom4J
(<a href=http://www.dom4j.com/ target=new>http://www.dom4j.com/</a>). The nice
thing about JDOM and Dom4J is that they
create Java object models which are easier to work with
than the DOM or SAX models that lower-level parsers
produce. For example, using Dom4J you would find a value like
this: SAXReader reader = new SAXReader(); Document document =
reader.read(new FileInputStream("file.xml")); Element
rootElement = document.getRootElement(); That would
give you the root element - then you can walk the XML
tree to find the element you want: Element
element = rootElement.getChild("firstChild"); String
text = element.getText(); There are also other
ways such as XPath, but you will need to look at that
on your own. Take a look at Dom4J or JDOM - trust me
when I say that it makes dealing with XML documents
easy. Sincerely, Anthony Eden
