Title: [SOLVED]William Yang HTMLParser Compile Problem
Post by: IndianaJones on July 19, 2011, 09:24:00 am

Hi all,
Has anyone experiencing with the William Yang HTMLParser?
I tried to compile the library but it gives the following error.

/Users/lazarus-libs/HtmlParser/HTMLParser.pas(96,69) Error: range check error in set constructor or duplicate set element
The error line is as follows.
Const
   Breaks = [#0..' ', #$3A..#$40, '-', '~', '{', '"', '''', '\', '}', '<', '>', '='];                 

Any idea?

The last 3 characters:

Code: [Select]

'<', '>', '='is already covered by:

Code: [Select]

#$3A..#$40Just delete them.

Hi again,
Has someone used this library before? Cos I cant figure out to get the text within the html tag like this.
In the following html text, I reached the href value, but not in the string.
<a href="/value/value">The text I want to get</a>

Any help would be appreciated. Thanks.

hi,
try write one on  your own if you don't find a solution.
It's not that difficult.

Cheers,,

    try
      Text := aHTML;
      aTag := TagByName['a'];
