No, again. Actually, TIDY does it but with bugs

No, if you think in terms of XHTML validation. Definetely not.

Yes of course. TIDY team could fix their bugs or I could even do the
tool myself but I do not have time to spend with that, unfortunatelly.

Yes of course, but I am trying to figure how to avoid it.
If there is no solution, I will do it myself of course. I am just
looking for this tool, it could help now and in the future.
Now to explain why I am saying that php is not generating HTML, and
why I don't care about php code.
Here is an example of a code IN THE PHP page (this is not the output)
<?php for ($i=1;$i<=10;$i++) {?>
<img src="<?php echo $fileName[$i]?>" >
<a href="<?php echo $link[$i]?>" > <?php echo $fileName[$i]?> </a>
<br>
<?php } ?>
A clever tool could say: OK, I don't care about php code, even if PHP
is generating HTML, I don't care!!
I don't want to validate XHTML output!!!!! (I DO NOT CARE ABOUT THE
OUTPUT) . I just want to validate the XHTML in the PHP page.
SO it could translate this like that
//REMOVED PHP TAG
<img src="//REMOVED PHP TAG" >
<a href="//REMOVED PHP TAG"> //REMOVED PHP TAG <br>
//REMOVED PHP TAG
then it could replace like that (by removing PHP code)
<img src="" >
<a href=""> </a><br>
it could say now:
warning: alt is missing in the IMG tag
warning: IMG tas is not closed
warning: BR tag is not closed
Then it could update and provide:
<img src="" alt=""/>
<a href=""> </a> <br/>
Then It will put the code back:
//REMOVED PHP TAG
<img src="//REMOVED PHP TAG" alt="" />
<a href="//REMOVED PHP TAG"> //REMOVED PHP TAG </a> <br/>
//REMOVED PHP TAG
then:
<?php for ($i=1;$i<=10;$i++) {?>
<img src="<?php echo $fileName[$i]?>" alt="" />
<a href="<?php echo $link[$i]?>" > <?php echo $fileName[$i]?> </a>
<br/>
<?php } ?>
Do you see now what I mean? Tidy does this work, but unfortunatelly
with some bugs.
This is easy to do, just an algorithm. Everybody who writes a
compilator one day know how it is easy (grammar etc etc).
Of course, this is easy because your are inserting PHP code in HTML
tags, which is the best solution to do.
When you are developping, If you separate the layers you have 2 php
pages for each page:
page1=> contains only php code (business layer)
page2 included at the end of page1 => contains ONLY HTML code with a
few php code ike "echo, if, while". The main rule is to put php within
HTML tags (like my example). The php code outside should never
generates HTML code. It should only be there to increment a loop or to
manage a loop.
Of course when I write this:
<?php for ($i=1;$i<=10;$i++) {?>
<img src="<?php echo $fileName[$i]?>" >
<?php } ?>
If you say that php is generating HTML code because it is repeating 10
times the <img> tag, then I understand why you don't understand what I
say!!
In this example I do not consider that PHP is really generating HTML
(it is repeating HTML code wich is *NOT* the same thing).
If you write this:
<?php echo"<img src="$fileName[$i]" >"
Then, php is genrating HTML code!! Everybody should avoid this, but
this is only my opinion.
The fact that PHP is repeating a line is not a problem with HTML
validation, because, if you are validating the HTML line (only 1),
then even if you duplicate this line ten times, the validation will
remain OK (maybe with some exceptions??).
That's why again I say it is easy. I really think you can validate
this:
<?php for ($i=1;$i<=10;$i++) {?>
<img src="<?php echo $fileName[$i]?>" >
<a href="<?php echo $link[$i]?>" > <?php echo $fileName[$i]?> </a>
<br>
<?php } ?>
without validating this:
<img src="file1" >
<a href="file1"> file1</a> <br>
<img src="file2" >
<a href="file2"> file2</a> <br>
<img src="file3" >
<a href="file3"> file3</a> <br>
<img src="file4" >
<a href="file4"> file4</a> <br>
.......... etc etc
