simple question for grabbing html tags out of string

[gene.ellis@gmail.com]

Good morning. I am racking my brains over what seems like should be a
simple question. I have a string that contains text and html.
Basically, I would like to grab the HTML tags from the string and wrap
some comment tags around it. Does anyone know how I would do this? I
was thinking about using the str_replace function, but this won't work
for certain html tags, such as <A href=#"> since the "#" won't be known
beforehand. Maybe a simple regular expression? Thank you so much for
your help!

You asked such a question before:

But never replied on followups...

Hey Daniel,

Thanks for the advice. The str_replace code is giving me a parse error.
It is saying "Parse error: parse error, unexpected ';" Do you know
where the error is taking place? Maybe a quote or something? Thank you.

Why? Wouldn't it be easiser to just strip the tags altogether?

But if you insist on doing it your way, here you go:

$string = "<p>This is HTML.</p>";
$string = str_replace('<' , '<!-- <', $string);
$string = str_replace('>' , '> -->', $string);

Hey NC,

Thanks for the advice. One question. Do you know of a way for it to
distinguish html tags from < and > signs? For example, I would like
this script to work on <p> but leave > and < alone. Thanks.

Would removing the tags completely work okay?

strip_tags($s);

< and > have no place in HTML. The fact that browsers tend
to display them correctly when they are not part of an HTML
tag is sheer goodwill on the part of browser developers and
should not be counted on. &lt; and &gt; should be used
instead.

Use a proper parser.

Once more and this must be a FAQ.
