|

This is basically what Tidy 04 August 2000 did and far more accurate
|
|
with respect to browser behaivour than the code commented out above.
|
|
Tidy could try to propagate the <pre> into each disallowed child where
|
|
<pre> is allowed in order to replicate some browsers behaivour, but
|
|
there are a lot of exceptions, e.g. Internet Explorer does not propagate
|
|
<pre> into table cells while Mozilla does. Opera 6 never propagates
|
|
<pre> into blocklevel elements while Opera 7 behaves much like Mozilla.
|
|
|
|
Tidy behaves thus mostly like Opera 6 except for nested <pre> elements
|
|
which are handled like Mozilla takes them (Opera6 closes all <pre> after
|
|
the first </pre>).
|
|
|
|
There are similar issues like replacing <p> in <pre> with <br>, for
|
|
example
|
|
|
|
<pre>...<p>...</pre> (Input)
|
|
<pre>...<br>...</pre> (Tidy)
|
|
<pre>...<br>...</pre> (Opera 7 and Internet Explorer)
|
|
<pre>...<br><br>...</pre> (Opera 6 and Mozilla)
|
|
|
|
<pre>...<p>...</p>...</pre> (Input)
|
|
<pre>...<br>......</pre> (Tidy, BUG!)
|
|
<pre>...<br>...<br>...</pre> (Internet Explorer)
|
|
<pre>...<br><br>...<br><br>...</pre> (Mozilla, Opera 6)
|
|
<pre>...<br>...<br><br>...</pre> (Opera 7)
|
|
|
|
or something similar, they could also be closing the <pre> and propagate
|
|
the <pre> into the newly opened <p>.
|
|
|
|
Todo: IMG, OBJECT, APPLET, BIG, SMALL, SUB, SUP, FONT, and BASEFONT are
|
|
dissallowed in <pre>, Tidy neither detects this nor does it perform any
|
|
cleanup operation. Tidy should at least issue a warning if it encounters
|
|
such constructs.
|
|
|
|
Todo: discarding </p> is abviously a bug, it should be replaced by <br>.
