DOM

• We may want to implement a small editor for address files
  • we need to access the XML data from a program
  • this is the role of the DOM
• DOM is a programmatic interface to the runtime XML tree
  • interface definition in OMG's IDL, ECMAScript and Java
  • others define language bindings (eg, for Python)
• Examples for DOM functions:

    nElements = dom.getElementsByTagName("Name")

    w = tel.getAttribute("where")

    if node.nodeType == node.TEXT_NODE: rc = node.data

    p = doc.createElement("Picture")

    p.setAttribute("width",800)

    pers.appendChild(p)
