Problem with regular expression

SiMZ

Hi,

I want to get the code inbetween the tags <body> and </body> .
First the contents are read from a file and then parsed.

$reg1 = "<";
$reg2 = "[Bb][Oo][Dd][Yy]";
$reg3 = ">";
$reg4 = "</";
$reg5= " |[:space:]";

$temp = file("Temp.txt");
$Str = implode($temp , "");

$start = (Som fun) ($Str, "$reg1($reg5)$reg2($reg5)$reg3");
$end = (Som fun) ($Str, "$reg4($reg5)$reg2($reg5)$reg3");
$insideBody = substr($Str, $start, ($end - $start));
if(ereg($Str, "$reg1($reg5)$reg2($reg5)$reg3"))
{
echo("<BODY> tag found <br>");
}
if(ereg($Str, "$reg4($reg5)$reg2($reg5)$reg3"))
{
echo("</BODY> tag found <br>");
}

echo("start: $start <br>");
echo("end: $end <br>");
echo($insideBody);

I have following problems in the coding:

A) Need a function at lines 8 and 9 to get the correct position
using regular expressions. Tried with substr(), but then again
the matching part has to be string.
😎 The 'IF' conditions at lines 11 and 15 never evaluates to TRUE.
This means that there is some error in the regular
expressions. Please check them. Right now I have ignored the
tag elements. Only looking against the < body > and </ body>
with spaces inbetween the word and the <, </ and >
characters.

You shouldn't post the exact same question in the exact same forum within a short amount of time.

Well at first I posted other problem... but then edited the last one to cover whole senario.. but title couldn't be changed.. therefore I posted it again to so that the new title could bring more attention towards the question.

You certainly don't mind making things difficult for yourself, do you?

if(preg_match("#<body[^>]*>(.*?)</body\s*>#is", $Str, $m))
    $insideBody = $m[1];
else
    echo "No proper body.";

With the [^>]* there in case the body tag has attributes and the \s* in case of whitespace.

I believe ereg and eregi also allow capturing parts of matched expressions - but preg_match() is faster anyway. Either way, it's ("regular expression", "string being searched").

Thanks it worked!
