preg-match-all

I am trying to come up with a regular expression in Perl matching multiple patterns and returning all of them like preg_match_all in PHP does. Here's what I have: $str = 'testdatastring'; if($str =~ /(test|data|string)/) { print "its found index location: $0 $-[0]-$+[0]\n"; print "its found index location: $1 $-[1]-$+[1]\n"; print "its found index location: $2 $-[2]-$+[2]\n"; print "its found index location: $3 $-[3]-$+[3]\n"; } This only gives me the first match which in this is 'test'. I want to be able to match all occurrences of specified patterns: 'test', 'data' and 'string'. I know that

I want to write a regex which extract the content that is between two tags <title> in a string but not the tags. IE I have the following <title>My work</title> <p>This is my work.</p> <p>Learning regex.</p> The regex (<title>)(.*?)(<\/title>) extracts <title>My work</title> but I want to extract only My work . How can I do that? This is a link to the example http://regex101.com/r/mD8fB0 You can use this following Regex: >([^<]*)< or, >[^<]*< Then eliminate unwanted characters like '<' & '>' the best way is to use Assertions, for your case, the regex would be: (?<=\<title\>).*?(?=\<\/title\>)

I'm using preg_match_all for very long pattern. when run the code, i got this error : Warning: preg_match_all(): Compilation failed: regular expression is too large at offset 707830 After searching, I got the solution, so I should increase value of pcre.backtrack_limit and pcre.recursion_limit in php.ini But after I increase the value and restart my apache, it still got the same problem. My PHP verison is 5.3.8 increasing the PCRE backtrack and recursion limit may fix the problem, but will still fail when the size of your data hits the new limit. (doesn't scale well with more data) example: <

I am trying to load a remote website and get all numbers that are inside of parentheses. But what ends up happening is it only matches the last value. Is my regex wrong? Am I using the correct flags? I have added the example of what it should match on in the second $html variable. //$html = file_get_contents("http://example.com/test.html"); $html = "(1234) (12) (1) \r\n (1346326)"; preg_match_all("^[(\d)]+$^", $html, $matches, PREG_PATTERN_ORDER); print_r($matches); echo "<br>"; foreach ($matches as $val) { echo "matched: " . $val[0] . "\n"; } Thanks. How about: preg_match_all("/\((\d+)\)/",

Some of my HTML files contains string like : {foreach $any_kind_of_charaters} Any kind of string including "\n\r" and spaces here {/foreach} I want to apply PHP's preg_match_all on them and wanna return a nice array like printed below Array ( [0] => {foreach $any_kind_of_charaters} Any kind of string including "\n\r" and spaces here {/foreach} [1] => any_kind_of_charaters [2] => Any kind of string including "\n\r" and spaces here ) This REGEX : /\{foreach\s+\$(.*)\}\s+(.*)\s+\{\/foreach\}/ working okay for me, but it fails when i add new lines(\n) between {foreach}{/foreach} tags. You help

This is a really simple problem, but I couldn't find a solution anywhere. I'm try to use preg_match or preg_match_all to obtain a string from within parentheses, but without the parentheses . So far, my expression looks like this: \([A-Za-z0-9 ]+\) and returns the following result: 3(hollow highlight) 928-129 (<- original string) (hollow highlight) (<- result) What i want is the string within parentheses, but without the parentheses. It would look like this: hollow highlight I could probably replace the parentheses afterwards with str_replace or something, but that doesn't seem to be a very

I have a string: This is a text, "Your Balance left $0.10", End 0 How can I extract the string in between the double quotes and have only the text (without the double quotes): Your Balance left $0.10 I have tried preg_match_all() but with no luck. As long as the format stays the same you can do this using a regular expression. "([^"]+)" will match the pattern Double-quote At least one non-double-quote Double-quote The brackets around the [^"]+ means that that portion will be returned as a separate group. <?php $str = 'This is a text, "Your Balance left $0.10", End 0'; //forward slashes are the

In PHP I have the following string : $str = "AAA, BBB, (CCC,DDD), 'EEE', 'FFF,GGG', ('HHH','III'), (('JJJ','KKK'), LLL, (MMM,NNN)) , OOO"; I need to split this string into the following parts: AAA BBB (CCC,DDD) 'EEE' 'FFF,GGG' ('HHH','III') (('JJJ','KKK'),LLL, (MMM,NNN)) OOO I tried several regexes, but couldn't find a solution. Any ideas? UPDATE I've decided using regex is not really the best solution, when dealing with malformed data, escaped quotes, etc. Thanks to suggestions made on here, I found a function that uses parsing, which I rewrote to suit my needs. It can handle different kind
