Always direct the user to the line where the crime occurred

[jidanni]

Don't say

line 53 column 3 - Info: missing optional end tag </li>

Say instead

line 53 column 3 - Info: this <li> tag is missing its optional end tag </li> further down

Or say

line 53 column 3 - Info: this <li> tag is missing its optional end tag </li> further down, at line 1234 column 3 in fact

Or best say

line 1234 column 3 - Info: the <li> tag back up at line 53 column 3 is missing its optional end tag </li> here

because that's where the "crime" occurred. Anywhere else and the user will be scratching thier head when looking at the HTML.

Otherwise "Gas leak at the corner of 35th and Roberts." So we go there and see nothing and then open up the full report. Oh, he started smelling gas at 35th, but forgot to tell us the actual leak was at 42nd.

Here is a skeleton of a different incident. I'm not attaching sample files. I'm just making this skeleton.

    124:  </li>
    126:  <li>   <--user's attention is sent here,
    153:    <li>
    168:    </li>
    170:    <li>
    196:    </li>
    198:    <li>
    202:    </li>
    204:    <li>
    221:    </li>
    223:    <li>
    240:    </li>
    242:    <li>
    255:    </li>
    257:    <li>
    275:    </li>
    277:    <li>
    280:    </li>
    310:  <li>   <--- when all along the user forgot to add a </li> before this line, here!
    405:  </li>

(Acutually li>|[dou]l> would be a better pattern that I could have used to show the structure here.)

Same problem with <dd>

line 413 column 5 - Info: missing optional end tag </dd>

Sorry. still version 5.6 on Debian
