[jdom-interest] validating XML without throwing a Java exception

[Rolf Lear]

Hi Cliff.

You can 'catch' the Exception for each string that you validate.

For example

SAXBuilder builder = new SAXBuilder();
for (String maybexml : stringstotest) {
  try {
    StringReader reader = new StringReader(maybexml);
    Document doc = builder.build(reader);
    ... do something with the well-formed document....
  } catch (JDOMException jdome) {
    // That string was not valid XML
    // do something about it....

    System.out.println("String " + maybexml + " was not XML: " +
jdome.getMessage());

  } catch (IOEXception ioe) {
    // StringReader should never throw an IOException.... but, just in
case
    ioe.printStackTrace();
  }
}
