  30. <P>PParse demonstrates progressive parsing.</P>
  31. <P>In this example, the application doesn't have to depend upon throwing
  32. an exception to terminate the parsing operation. Calling parseFirst() will
  33. cause the DTD to be parsed (both internal and external subsets) and any
  34. pre-content, i.e. everything up to but not including the root element.
  35. Subsequent calls to parseNext() will cause one more piece of markup to
  36. be parsed, and propagated from the core scanning code to the parser. You
  37. can quit the parse any time by just not calling parseNext() anymore
  38. and breaking out of the loop. When you call parseNext() and the end
  39. of the root element is the next piece of markup, the parser will
  40. continue on to the end of the file and return false, to let you
  41. know that the parse is done.</P>

  47. This program demonstrates the progressive parse capabilities of
  48. the parser system. It allows you to do a scanFirst() call followed by
  49. a loop which calls scanNext(). You can drop out when you've found what

  51. 16 new elements then sets a flag to indicate its found what it wants.
  52. At that point, our progressive parse loop exits.

  54. -v=xxx - Validation scheme [always | never | auto*].
