Elgg core produces invalid XHTML

[aszepeshazi]

Checked a couple of Elgg pages in the W3C validator ​http://validator.w3.org/), with the following results:

​http://elgg.skawa.hu/ (my own Elgg testsite) - 18 errors
​http://elgg.skawa.hu/pg/file/use[svn:20]/read/506/raymond-cvikota - 25 Errors, 18 warnings

​http://community.elgg.org/ - 35 errors, 1 warning
​http://community.elgg.org/pg/groups/forum/15815/ - 194 Errors, 190 warnings
​http://community.elgg.org/mod/plugins/world.php - 40 Errors, 6 warning(s)
​http://community.elgg.org/mod/groups/discussions.php -165 Errors, 82 warning(s)

I realize that a number of the errors come from plugins (like the groups plugin), but the core has it's share of invalid markup as well. As I see, every single page rendered by Elgg breaks XHTML validity.

A couple of these XHTML errors are quite serious:

• duplicated ids

• mismatched <td> and <tr> tags

• unencoded links having special characters (i.e. ampersand)

• misplaced <div>, <h3>, etc tags

Sorry that I'm unable to give very specific report on where and what tags are broken, but as of the moment this seems a system-wide issue for me. My best bet would be to go through all pages in a validator, one by one.

If you're unable to address this in the near future, I will have some spare time next month, and will be happy to assist with it.

Why has the priority of this been downgraded from major to minor and minor to trivial. Some of these errors are not trivial at all (especially the repeat use of id's obviously). How can I help to contribute and correct them

This ticket is too general. We need specific tickets that point out the problems. For example, where in the code are there mismatched <td> and <tr> tags? I recommend creating tickets that all have "invalid XHTML" in the title that make it easier to track these items.
