RE: [Htmlparser-developer] Label Tag

[<dha...@or...>]

Hi Somik,

The mechanism suggested by you to replace the node is not working. I am
attaching a piece of code I wrote in LabelScannerTest to test the same.

public void testSettingLabels() throws ParserException {
            createParser("<label><span>Jane <b> Doe </b>
Smith</span></label>");
            parser.registerScanners();
            LabelScanner labelScanner = new LabelScanner("-l");
            parser.addScanner(labelScanner);
            parseAndAssertNodeCount(1);
            assertTrue(node[0] instanceof LabelTag);
            
            LabelTag labelTag = (LabelTag) node[0];
            assertStringEquals("Label","<LABEL><SPAN>Jane <B> Doe </B>
Smith</SPAN></LABEL>",labelTag.toHtml());

            Node [] nodeArray = labelTag.getChildrenAsNodeArray();
            StringNode node = new StringNode(new StringBuffer("New
Label"), 0, 0);
            nodeArray[0] = node;
            for(int i=1;i<nodeArray.length;i++)
            {
                  nodeArray[i] = null;
            }
            assertEquals("Label value","New
Label",labelTag.getChildrenHTML());
            assertEquals("Label value","New Label",labelTag.getLabel());
            assertStringEquals("Label","<LABEL>New
Label</LABEL>",labelTag.toHtml());
      }

No, sorry wont do - you have to copy 10 essays (or
programs) in detention :). Chill out!

That would work - but would be costly (in
performance). You really dont want to rig up an
internal parser just to change the label tag data.

A simpler way is to find out which string node you
wish to change (digupStringNode(), searchFor(), or
quite simply, the exact index which you might happen
to know). 

Then,
StringNode newNode = new StringNode(
   newDataBuffer, 0, 0
);
To replace the child, you can either do something as
simple as,

getChildrenAsNodeArray()[posOfOldNode] = newNode; 

or
NodeList nodeList = getChildren();

and make a similar modification in the nodelist.

Regards,
Somik
