get a sentence from HTML doc

scoppc

I think this should be interesting.

Anyone know how to get the sentence \'I want to get out\' from the following HTML document???

--- how.php ---

<head>
<title>get the sentence ONLY</title>
</head>
<body>
I want to get out
</body>

I mean use some kind of parsing techniques. I can\'t figure it out.

What do you want to do, just see if the sencence is in there?

You can read in your html file...

Straight from your friendly neihborhood PHP Manual...

// get contents of a file into a string
$filename = "/usr/local/something.txt";
$fd = fopen ($filename, "r");
$contents = fread ($fd, filesize ($filename));
fclose ($fd);

Now just use a regex function to match the text you're looking for...

preg_match ("/'I want to get out/i", $contents , $matches);

$matches is an array of matches ;-)

I suspect however that you may be looking for unspecific content in the HTML doc.

So this pattern expression is probably what you want, if not then you need to be more specific ;-)

Get everything between the body tags...

preg_match ("/<body[^{>]+>.+<\/body>/i",} $contents , $matches);

Reset $contents...

$contents = $matches[0];

Finally, get rid of the body tags and any other html tags that still remain...

$contents = eregi_replace ( "<[^>]*>", "", $contents);

Warning, these patterns are off the top of my head and untested, but that will give you an idea.
