I'm looking for a DOM-style XML parser that doesn't load the entire document. Rather, it would let you get an element, then iterate over the element's children, presenting each child as a DOM node but only loading one child at a time (to conserve memory when there's a large number of children. Where I can get such a parser?

You can use JDOM API (See also JSR0102) to achieve this effect. The following snippet of code shows how JDOM can be used to get the java.util.List of child(ren) of a node. In JDOM, a node is said to be org.jdom.Element.

org.jdom.input.SAXBuilder builder = new org.jdom.input.SAXBuilder();
org.jdom.Element root = builder.build(new java.io.File("file.xml")).getRootElement();
java.util.List children = root.getChildren();
An org.jdom.Element can be convert to org.w3c.dom.Element by using org.jdom.output.DOMOutputter class. Moreover, JDOM lets you change the modify the document without having to worry about underlying parser. See also: Parsing a very large XML file FAQ.
