* This is a function that searches for, and attempts to correct certain issues with ul/ol html lists.
|
|

1778 |
* This is needed because these lists are used heavily in page layout, and content with bad tags can
|
|
|
1779 |
* lead to broke course pages.
|
|
|
1780 |
*
|
|
|
1781 |
* The theory of operation here is to linearly process the incoming content, counting the opening and closing
|
|
|
1782 |
* of list tags, and determining when there is a mismatch.
|
|
|
1783 |
*
|
|
|
1784 |
* The specific issues this should be able to correct are:
|
|
|
1785 |
* - Orphaned li elements will be wrapped in a set of ul tags.
|
|
|
1786 |
* - li elements inside li elements.
|
|
|
1787 |
* - An extra closing ul, or ol tag will be discarded.
|
|
|
1788 |
* - An extra closing li tag will have an opening tag added if appropriate, or will be discarded.
|
|
|
1789 |
* - If there is an unmatched list open tag, a matching close tag will be inserted.
|
|
|
1790 |
*
|
|
|
1791 |
* It does it's best to match the case of corrected tags. Even though not required by html spec,
|
|
|
1792 |
* it seems like the safer route.
|
|
|
1793 |
*
|
|
|
1794 |
* A note on parent elements of li. This code assumes that li must have a ol or ul parent.
|
|
|
1795 |
* There are two other potential other parents of li. They are menu and dir. The dir tag was deprecated in
|
|
|
1796 |
* HTML4, and removed in HTML5. The menu tag is experimental as of this writing, and basically doesn't work
|
|
|
1797 |
* in any browsers, even Firefox, which theoretically has limited support for it. If other parents of li
|
|
|
1798 |
* become viable, they will need to be added to this code.
