Hi,
my reguler expression is the following :
headlineRegex -> (<h1>)?(.*)</h1>
group -> 2
I am using the regular expression above to extract a headline (h1) from
an HTML document
while (mHeadlineRE.match(content, offset)) {
For some Html pages this regular expression works,
but for some Html pages, it gives the following errors :
[...]

net.sf.regain.crawler.preparator.html.HtmlContentExtractor.extractHeadli
nes(HtmlContentExtractor.java:140)
on this line :
while (mHeadlineRE.match(content, offset)) {
when I use this regex : <h1>(.*)</h1>
group 1
I never have this error.
The problem is that I don't even know how to debug this error, that's
why I am asking for some help here.
Any help is very appreciated, thank u!
