So ok, I found a solution - surely not the optimal one - but I will
share my experience with you.
HtmlParser is not "extends enabled" because:
1 - all attributes are private and have to be protected
2 - resolve() is in the same case
3 - call to super.startElement() is not so easy because of
body/title/discard level counting.
HtmlParser is more extendEnabled, but the only reason why I extend this
class is to modify the "hardcoded" new HtmlHandler in expression
parser.setContentHandler(new XHTMLDowngradeHandler( new
HtmlHandler(this, handler, metadata)));
to MyHtmlHandler(...).
Maybe a configuration solution for this class instanciation will be
profitable.
Can you tell me if I don't take the right way, and if a possibility to
"overwrite/extend" the features of parser is in your roadmap ?
My two pences...
have a good day

Hi all,
I work on html parsing via generic AutoDetectParser() class.
I have to keep some "specific" attributes (id and class) in <table>
attribute in order to detect witch table have "meaning" for my app.
So, as far as I understand for now, I have to :
- extend HtmlHandler with MyHtmlHandler
- in MyHtmlHandler override public void startElement(...) with something
like this :
if (bodyLevel == 0 && discardLevel == 0) {
if ("TABLE".equals(name)){
AttributesImpl attributes = new AttributesImpl();
String id = atts.getValue("id");
String class = atts.getValue("class");
if (id != null){
attributes.addAttribute("", "id", "id", "CDATA", id);
}
if (class != null){
attributes.addAttribute("", "class", "class", "CDATA", class);
}
xhtml.startElement("http://www.w3.org/1999/xhtml";, "table", "table",
attributes);
}
else{
//if other that table
super.startElement(...)
}
else{
//if other bodyLevel and discardLevel
super.startElement(...)
}
- And finally pass MyHtmlHandler to parse() method via parseContext.

* This is the right way to do such a thing ?
* How I can use the parseContext to pass MyHtmlHandler ? I don't find any
example on it...
Any comment will be much appreciated,
Have a good day
