Hey all!

To say I suck at regex is an understatement so really need any I can get on this, I have a page of text with different html tags in them, but each "block" of text has a <p> or a < class="something"> tag... anybody have any regex that will catch each of these paragraphs and put then into an array
example:
array[0]="<p> first block </p>";
array[1]="<p class="blah"> block X</p>";

Thanks!
R

If you're using php5 you can use DOM's getElementsByTagName.

If you still think you need to do some sort of regex it is possible
but it will be buggy at best.

Hi,

Maybe the example is overkill, but I give you a quick setup that can
save you some time finding HTML tags with a certain attribute.

<?php

$html = <<<END_OF_HTML

<b>hello</b>
<b class="blah">hello</b>
<p>hello</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">hello</a>
END_OF_HTML;

$tags = array();
$tags[] = 'p';
$tags[] = 'a';

$tags = implode('|', $tags);

$pattern = '/<('.$tags.')[^>]*>/i';

echo $pattern."\n";

preg_match_all($pattern, $html, $matches);

var_dump($matches);

?>

I'm not an expression guru either, but I think it works OK. I had to
find 'link', 'img', 'a' and other tags in HTML and used a more complex
expression for it which worked like a charm.

It's just an example. For you, you have to leave away the 'a' tag in the
$tags array, to get what you want.

Hope it s!

Hi,

I'm sorry. I didn't read your request properly. Below you'll have a
correct solution:

<?php

$html = <<<END_OF_HTML

<b>hello</b>
<b class="blah">hello</b>
<p>hello</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">this</a>
<a>hello</a>
<a href="regex yo">hello</a>
<a>hello</a>
<a id="2" href="regex yo">hello</a>
<p>that</p>
<p class="blah" title="whatever">hello</p>
END_OF_HTML;

$tags = array();
$tags[] = 'p';
$tags[] = 'a';

$attr = array();
$attr[] = 'class';
$attr[] = 'href';

$vals = array();
$vals[] = 'blah';
$vals[] = 'url';
$vals[] = 'yo';

$text = array();
$text[] = 'hello';
$text[] = 'this';
$text[] = 'that';

$tags = implode('|', $tags);
$attr = implode('|', $attr);
$vals = implode('|', $vals);
$text = implode('|', $text);

$pattern =
'/<('.$tags.')[^>]*('.$attr.')[^>]*('.$vals.')[^>]*>('.$text.')[^<\/]*<\/\1>/i';

echo $pattern."\n";
echo "--------------------\n";

preg_match_all($pattern, $html, $matches);

var_dump($matches);

?>

Hi,

It is obvious I haven't had my caffeine yet. This is my last try to get
the pattern straight:

<?php

$html = <<<END_OF_HTML

<b>hello</b>
<b class="blah">hello</b>
<p>those</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">this</a>
<a>rose</a>
<a href="regex yo">hello</a>
<a>nose</a>
<a id="2" href="regex yo">hello</a>
<p>that</p>
<p class="blah" title="whatever">hello</p>
END_OF_HTML;

$tags = array();
$tags[] = 'p';
$tags[] = 'a';

$attr = array();
$attr[] = 'class';
$attr[] = 'href';

$vals = array();
$vals[] = 'blah';
$vals[] = 'url';
$vals[] = 'yo';

$text = array();
$text[] = 'hello';
$text[] = 'this';
$text[] = 'that';

$tags = implode('|', $tags);
$attr = implode('|', $attr);
$vals = implode('|', $vals);
$text = implode('|', $text);

$pattern =
'/<('.$tags.')[^>]*('.$attr.')?[^>]*('.$vals.')?[^>]*>('.$text.')[^<\/]*<\/\1>/i';

echo $pattern."\n";
echo "--------------------\n";

preg_match_all($pattern, $html, $matches);

var_dump($matches);

?>

/'What you would like to be done to you, do that to the other....'/

Or you could simplify and just do this:

$html = <<<END_OF_HTML
<b>hello</b>
<b class="blah">hello</b>
<p>those</p>
<p class="blah">hello</p>
<a>hello</a>
<a href="url">this</a>
<a>rose</a>
<a href="regex yo">hello</a>
<a>nose</a>
<a id="2" href="regex yo">hello</a>
<p>that</p>
<p class="blah" title="whatever">hello</p>
END_OF_HTML;

// This will give you any tag
preg_match_all("/<[\s\S]*?>*?<\/[\s\S]*?>/", $html, $matches);
print_r($matches);

// This will give you any p tag
preg_match_all("/<p[\s\S]*?>*?<\/p[\s\S]*?>/", $html, $matches);
print_r($matches);
