<div>Hello,<br /><br /></div>
In my project I need to extract links from HTML document.</div>
For this purpose I've prepared ragel HTML grammar, primarily based on this work:<br /><a href="https://github.com/brianpane/jitify-core/blob/master/src/core/jitify_html_lexer.rl">https://github.com/brianpane/jitify-core/blob/master/src/core/jitify_html_lexer.rl</a></div>
(mentioned here: <a href="http://ragel-users.complang.narkive.com/qhjr33zj/ragel-grammars-for-html-css-and-javascript">http://ragel-users.complang.narkive.com/qhjr33zj/ragel-grammars-for-html-css-and-javascript</a> )<br /><br /><br /></div>
Almost all works well (thanks for the great tool!), except one issue I can't overcome to date:<br /><br />If I specify this thext as an input:<br />bbbb <a href="first_link.aspx"> cccc<a href="/second_link.aspx"></div>
my parser can correctly extract first link, but not the second one.</div>
The difference between them is that there is a space between 'bbbb' and '<a', but no spaces between 'cccc' and '<a'.</div>
<br />In general, if any text, except spaces, exists before '<a' tag it makes parses consider it as content, and parser do not recognize tag open.<br /><br /></div>
Could please anyone give any hint how to improve existing grammar, in order to make it recognize tag open?<br /><br /></div>
Please find attached intentionally simplified sample with grammar, aiming to work as C program ( ngx_url_html_portion.rl ).</div>
There is also input file input-nbsp.html , which expected to contain input for the application.<br /><br /></div>
In order to play with it, make .c-file from grammar:</div>
ragel ngx_url_html_portion.rl
<div>
<div>
<div>then compile resulting .c-file and run programm.</div>
<div>Input file should be in the same directory.<br /><br /></div>
