Example 21 with DOMImplementation

use of org.w3c.dom.DOMImplementation in project j2objc by google.

the class DOMHelper method getParentOfNode.

/**
   * Obtain the XPath-model parent of a DOM node -- ownerElement for Attrs,
   * parent for other nodes. 
   * <p>
   * Background: The DOM believes that you must be your Parent's
   * Child, and thus Attrs don't have parents. XPath said that Attrs
   * do have their owning Element as their parent. This function
   * bridges the difference, either by using the DOM Level 2 ownerElement
   * function or by using a "silly and expensive function" in Level 1
   * DOMs.
   * <p>
   * (There's some discussion of future DOMs generalizing ownerElement 
   * into ownerNode and making it work on all types of nodes. This
   * still wouldn't help the users of Level 1 or Level 2 DOMs)
   * <p>
   *
   * @param node Node whose XPath parent we want to obtain
   *
   * @return the parent of the node, or the ownerElement if it's an
   * Attr node, or null if the node is an orphan.
   *
   * @throws RuntimeException if the Document has no root element.
   * This can't arise if the Document was created
   * via the DOM Level 2 factory methods, but is possible if other
   * mechanisms were used to obtain it
