I think xml extensions support parsing for html

Re: Analyze and read in html file

I thought that only XHTML is XML compatible, but not HTML.
So it would not be possible to read it via XML extension.

Can someone please comment on that thought?

Thx

These are rather sweeping descriptions - not actual language descriptions.
The short answer is that if your code isn't xml you need to get it fixed
soon.

Be warned that there are two kinds of HTML: SGML-HTML, as specified
in HTML specs, and tag-soup-HTML, as digested by browsers.

In php, not that I know off though I would like to be wrong.

If you know any perl then use the excellent HTML::Parser. It handles just
about anything that a web site might throw at it. You could use the perl
script to build a PHP script

Assume text input something like

<html><head><ti tle>example page</title> (etc)

So write a perl script with handlers something like (totally pseudo code)

sub do_start_tag
{
my $tag_name = this is available in the parser, but I forget how
print TMP_PHP_SCRIPT , "handle_tag('$t ag_name');\n";
}

sub do_text
{
my $raw_text = this is available in the parser, but I forget how
my $safe_text = quotemeta($raw_ text);
print TMP_PHP_SCRIPT , "handle_text('$ safe_text');\n" ;
}

sub do_end_tag
{
my $tag_name = this is available in the parser, but I forget how
print TMP_PHP_SCRIPT , "handle_end_tag ('$tag_name');\ n";
}

From that you would get a temporary files with lines like

handle_tag('htm l');
handle_tag('hea d');
handle_tag('tit le');
handle_text( 'example page');
handle_end_tag( 'title');
handle_end_tag( 'head');

Your main php script would run the perl script, and then run the temporary
php script (example shown just above), and your php functions like
handle_tag etc would be called just as if you had been able to parse the
data directly from within php.
