[js] HTML to XHTML

Hello,

I'm currently building a HTML to XHTML parser in JavaScript. I've made a function toArray(); to explode an input string. (ie <b>test</b> becomes array('<b>', 'test', '</b>'));

That function also corrects the HTML following the XHTML standard. The toArray() function returns an Array. That Array is fully XHTML compatible, execpt the nesting part.

Does anyone know of the existance of an algorithm that corrects the nesting of tags?

uhh.. that is not that simple.

html parsers are very hard to do, since html is really sgml, which is a big brother of xml. xml (and xhtml) was invented to be easier to parse, even if it less capable than sgml.

so, no, i don't think it can easily be done with js.


now, if you are willing to do it on the server side (php?), there is html tidy program that parses "html tag soup" ;) (and/or converts it to xhtml)

http://tidy.sourceforge.net/


even better thing is that libtidy will soon be an extension to php, so, we will be able to do all sorts of neat stuff with it

Well,

I finally managed to create a working parser. This parser converts HTML into XHTML. It's 95% safe and now I'm going to add some new things that are not compatible now. (ie: and IMG tag must have an alt attribute, enz)

I prefer a JS version, since some CMS Wysiwyg editors need XHTML support. Those editors are often made compatible for several programming languages like PHP, ASP, CF, Perl...
So, a JS parser is a perfect solution.
My parser parser a 120kb file (2100 lines of code) in 1.6 sec.

are you willing to share that code? ;)

Actually I'm not,

Good HTML to XHTML parsers are hard to find and I've spend lots of hours performance tuning. I'm going to sell the script to several CMS companies.
I already have a customer (yoehoe)...

My script reduced the number of errors on www.devarticles.com from 492 to 16... That's 97% reducing...

So, unfortunately I'm not going the share this stuff
