1.16. Mixing the DOM and SAX Models

  • Use the DOM (Document Object Model) for node traversal (sending information between nodes) and pre-existing scripting/template engines.
  • Use the DomModelCreator visitor class to mix SAX and DOM models. When used with SAX filtering, this visitor will construct a DOM fragment from the visited element. It allows you to use DOM utilities within a streaming environment.
  • When more than one model is nested, the outer models will never contain data from the inner models (that is, the same fragment will never co-exist inside two models): 
    <order id="332">
    <header>
        <customer number="123">Joe</customer>
    </header>
    <order-items>
        <order-item id='1'>
            <product>1</product>
            <quantity>2</quantity>
            <price>8.80</price>
        </order-item>
        <order-item id='2'>
            <product>2</product>
            <quantity>2</quantity>
            <price>8.80</price>
        </order-item>
        <order-item id='3'>
            <product>3</product>
            <quantity>2</quantity>
            <price>8.80</price>
        </order-item>
    </order-items>
</order>
