regex to match all *texttexttext in a string
I need a regex that will match all strings starting with * until it meets a <
so in this 开发者_StackOverflowblock of text: bob went to the *store and he bought a toy and <then he went outside *and went to his car for <a ride.
it would match bob went to the *store and he bought a toy and
and and went to his car for
and if there is no "<" it will match all until the end of the line
try this:
<pre>
<?
$s = 'bob went to the *store and he bought a toy and <then he went outside *and went to his car for <a ride.';
preg_match_all("/\*([^<]+)/", $s, $matched);
print_r($matched);
?>
output:
Array
(
[0] => Array
(
[0] => *store and he bought a toy and
[1] => *and went to his car for
)
[1] => Array
(
[0] => store and he bought a toy and
[1] => and went to his car for
)
)
It should be something like:
With PHP:
preg_match_all("#\*(.+?)<#", $stringWithText, $matches, PREG_SET_ORDER);
$mCount = count($matches);
foreach ($matches as $match)
echo "Matched: " . $match[1] . "<br/>";
If you want to skip the end "<" the change the expression to #\*(.+?)<?#
and if you want to allow line changes, use these flags:
preg_match_all("#\*(.+?)<#si", $stringWithText, $matches, PREG_SET_ORDER);
Notice the si flags trailing the expression
Hope it helps
Try \*(.+?)<
You can use this tool to experiment with regex: http://gskinner.com/RegExr/
EDIT
To keep matching to a <
OR to the end of the string, use:
\*(.+?)[<|$.*]
I would use something like this
(?<=\*).*?(?=<|$)
See it here on Regexr
(?<=\*)
is a look behind, it matches no character, but it ensures, that the character before is a *
.*?
matches everything non greedy
(?=<|$)
is a look ahead, it matches no character, but it ensures, that the following character is a <
or a $
(row end) ==> use the m (multiline) modifier, otherwise the $
will match only the end of the string and not the end of the row.
