The issue seems to be with parsing of <link rel="..." href="..."> type elements in an HTML page. What I observed is that the parser is trying to interpret the value for href given inside double-quotes. The value contains a "-" (e.g. "<a href="http://some.domain.com/some-page-etc-etc" target="_blank" class="">http://some.domain.com/some-<wbr class="">page-etc-etc</a>"). The "-" sign is being interpreted as minus and then things go wrong. In another case I found that "\g" embedded in the value (e.g. "<a href="http://some.domain.com/some-page/global/something" target="_blank" class="">http://some.domain.com/some-<wbr class="">page/global/something</a>") is also creating issues. In essence, the parser is trying to interpret the value, which I believe, it should not.</div><div class=""><br class=""></div><div class="">I am willing to dive further into it to debug and fix the issue, but looking at the complexity and size of WebCore, I think I would benefit a lot to expedite a fix, if I could get some tips about which code area/functionality I should specifically focus in the WebCore. Looking forward to some help in this regard.</div><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Atul.</div><div class=""><br class=""></div></div>
