[Htmlparser-developer] Re: [Htmlparser-user] HTML parser 1.1

[Somik R. <so...@ya...>]

Hi Raghav
    I replied to your earlier query. Did you recieve the mail (I forwarded
it again) ?
    Regarding your current query, there are two ways to handle option tags.

[1] Like in the previous question, you will have to recognize a HTMLTag
(begin tag), followed by HTMLStringNode, and finally HTMLEndTag.
[2] To make life easier, since this tag is basic xml, you can use a special
XML parsing method provided in the superclass HTMLTagScanner.

The methods are :
(i) isXMLTagFound
(ii) extractXMLData

both of them are static mehods.
You would use it like this :

HTMLNode node = reader.readElement();
if (isXMLTag(node,"OPTION")) {
    String option = extractXMLData(node,"OPTION",reader);
    // The string now contains the data within the option xml tag
    // So given an input : <OPTION value="#">Select a destination</OPTION>
    // option will hold "Select a destination"
}

But getting the value from the option tag itself would need to be handled
seperately.

Regards,
Somik
