You can. The following example of how to manipulate the generated HTML, was
documented somewhere in the ND 3.1 Docs.
=========================================================================
Make changes to the generated HTML after the fact. This requires redirection
of the output stream to an internal buffer before the display() begins.
Then, once this event is triggered, you can obtain the generated HTML, make
modifications to it (e.g. by replacing some place holder token with the
"latest news" String) and write out the final results. Here is the framework
for this technique:
protected int
onBeforeDisplayEvent (
)
{
// Save the original output stream
_origStream = CSpider.getOutputStream ();
// Construct a byte array output stream and create a
// CSpStringOutputStream out of it
_myArrayStream = new ByteArrayOutputStream (10000);
_myStream = new CSpStringOutputStream (_myArrayStream);
// Set our temporary string output stream to be used
// when constructing the HTML ("stealing" the HTML page)
CSpider.setOutputStream (_myStream);
return (PROCEED_WITH_BUILTIN_HANDLING);
}
protected int
onBeforeHtmlOutputEvent (
)
{
try
{
// Flush everything so that our byte array will get loaded
// with the HTML
CSpHtml.flush (_myStream);
// Convert the byteArray into a String
String htmlPage = _myArrayStream.toString ();
// Restore the original output stream
CSpider.setOutputStream (_origStream);
// Make some late changes to the HTML
String modifiedHtmlPage =
CSpUtil.replaceSubstring (htmlPage,
............);
// Write the modified HTML out
CSpHtml.sendRawDataItem (_origStream, modifiedHtmlPage);
}
catch (Exception ex)
{
// Shouldn't occur
}
return (PROCEED_WITH_BUILTIN_HANDLING);
}
protected CSpStringOutputStream _origStream = null;
protected ByteArrayOutputStream _myArrayStream = null;
protected CSpStringOutputStream _myStream = null;
