• txt"lth1gtTraversing the node treelt/h1gt"
• document.write(txt)
• set xmlDocCreateObject("Microsoft.XMLDOM")
• xmlDoc.async"false"
• xmlDoc.load("note.xml")
• for each x in xmlDoc.documentElement.childNodes
• document.write("ltbgt" x.nodename "lt/bgt")
• document.write(" ")
• document.write(x.text)
• document.write("ltbrgt")
• next
• lt/scriptgt

Sample code

• public class OtherParser implements Parser
• private Document doc
• public OtherParser(Document arg)
• doc arg
• public SourceTuple parseDoc()
• String protocolnull
• String urlnull
• int size-1
• String typenull
• long created-1
• long last_mod-1
• String srcnull
• String opt null
• Element root

• System.err.println(url)
• return new SourceTuple(-1, protocol, url, size,
  type, created, last_mod, src, -1, opt)
