Usage

From source file:Main.java

/**
 * Return the content of the given element.
 * <p/>/*  w  w  w .  jav a2s  .  co m*/
 * We will descend to an arbitrary depth looking for the first text node.
 * <p/>
 * Note that the parser may break what was originally a single string of
 * pcdata into multiple adjacent text nodes. Xerces appears to do this when
 * it encounters a '$' in the text, not sure if there is specified behavior,
 * or if its parser specific.
 * <p/>
 * Here, we will congeal adjacent text nodes.
 * <p/>
 * We will NOT ignore text nodes that have only whitespace.
