got it. Thanks a lot premiso!

I use regEx's to get the URL out of HTML in a webpage it comes out with the & bla.....<a href="/template/NamlServlet.jtp?macro=app_people&node=136&i=20" title="Page 2">....bla My understanding is that HTML translates the & to just & when a user clicks the link but when I use file_get_contents to see the url with the & it doesn't like it so I have to use preg replace to remove it. McK

Hey guys! I have a url with ....&..... and was trying to use urldecode to change it to .....&....... but I see now urldecode doesn't do that. Is there a function that does do it so I don't have to replace "amp;" with "" manually? I know preg_replace("/amp;/", "", $tempURL); works but is that what is typically used? Thanks! McK

Thanks! No prob. Its funny. Yesterday and today I have been running into security issues---500 errors. Apparently their servers block the file_get_contents function for personal pages..... Oh well, if I don't find another way---live and learn. Thanks for your help. McK

No its not my server. I am tagging protege forum users locations (if they decide to add their locations) with google maps api (KML) so members can find other protege users in their area and connect. McK

No. No. No. I am learning to use a software called Protege for building ontologies and would like to be able to get more involved with the Protege user community but there is not way to tell if there are any users in my area. I was learning to use KML with google maps and thought that if people that are members of the forum could see other members tagged on google maps with a link to their email they can contact local users in their area by clicking their email link. AND its perfect because I don't know a lot about security so the forum takes care of that by not letting them log in to send an email if they are not registered! I am not a spammer. I have morals. Check out the pic attached of the website I am trying to build for this to happen. Ultimately...I would like to send what I have done to them and ask if they would be willing to put a link on their site to my site that allows users to connect with others in their area. If they say no...well, I will have learning a lot from the exercise. No problem! You have every right to ask. McKinnley

Hey! I am trying to get a database table of users but am running into the error: Warning: file_get_contents(http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=68583) [function.file-get-contents]: failed to open stream: HTTP request failed!

Any way around this? <?PHP $maxPage = 0; $mainPage = "http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=app_people&node=136"; $mainContent = file_get_contents($mainPage); $pattern = "/(?<=\"Page )\d\d+/"; preg_match_all($pattern, $mainContent, $pageNumb); //find the max page for($i=0;$i<sizeof($pageNumb[0]);$i++) { if($pageNumb[0][$i] > $maxPage) { $maxPage = $pageNumb[0][$i]; } } //echo('Max page is: '.$maxPage.'\n'); //Get an array of all the pages $pages = array(); for($i=1;$i<$maxPage;$i++) { $pages[$i] = "http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=app_people&node=136&i=".($i*20); } //print_r($userPages); //Get personal page urls and add to MySQL mysql_connect("localhost" , "root") or die("Cant connect"); mysql_select_db("protegeusers") or die("Cant find database"); foreach($pages as $url) { $urlContents = file_get_contents($url); $pattern = "/http:\/\/protege-ontology-editor-knowledge-acquisition-system\.136\.n4\.nabble\.com\/template\/NamlServlet\.jtp\?macro=.+;user=\d+/"; preg_match_all($pattern, $urlContents, $personalPage); foreach($personalPage as $user) { for($i=0; $i<sizeof($user);$i++) { [color=green]$userContents = file_get_contents($user[$i]);[/color] $pattern1 = "/user\/SendEmail\.jtp\?type=user.+;user=\d+/"; $pattern2 = "/(?<=\">Send Email to ).+(?=<)/"; preg_match_all($pattern1, $userContents, $userEmail); preg_match_all($pattern2, $userContents, $username); [color=green]print_r($username); print_r($email);[/color] //$query = "INSERT INTO users (username, userurl) values ('$userName','$userUrl')"; //mysql_query($query); } } } ?>

Okay I see. That makes sense that you can't skip over a part. Thank you for the explanation.

Sure! <a href="/user/SendEmail.jtp?type=user&user=195799">Send Email to shreyes</a>

The url isn't the test string. When I say file_get_contents it returns a string of the html contents of the page so that is the string it is searching.

Sorry, I copied it to here from a regex tester where I didn't need to escape the the quote but in my php code I actually did and its still feeding me empty arrays. Array ( [0] => Array ( ) [1] => Array ( ) [2] => Array ( ) ) $url = file_get_contents("http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=68583"); $pattern = "/(user\/SendEmail\.jtp\?type=user&user=\d+)((?<=\"<Send Email to ).+(?=<))/"; preg_match_all($pattern, $url, $userInfo); print_r($userInfo); // echo('Email: '.$userInfo[1][0]); // echo('Name: '.$userInfo[2][0]);

Got it. That makes perfect sense. If you don't mind I have just one more for you. You introduced me to using groups with regex's which I read a bit about and have been playing with. However, when I try to use a positive look ahead and positive look behind together and they don't work...but individually they do. I found anything that sheds light on why. //This works: $url = file_get_contents("http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=68583"); $pattern1 = "/user\/SendEmail\.jtp\?type=user.+;user=\d+/"; $pattern2 = "/(?<=\">Send Email to ).+(?=<)/"; preg_match_all($pattern1, $url, $useremail); preg_match_all($pattern2, $url, $username); print_r($useremail); print_r($username); //This doesn't: $url = file_get_contents("http://protege-ontology-editor-knowledge-acquisition-system.136.n4.nabble.com/template/NamlServlet.jtp?macro=user_nodes&user=68583"); $pattern = "/(user\/SendEmail\.jtp\?type=user&user=\d+)((?<="<Send Email to ).+(?=<))/"; preg_match_all($pattern, $url, $userInfo); echo 'UserEmail: '.$userInfo[1][0] echo 'UserName: '.$userInfo[2][0]

Hey guys! Thanks for the input--things are working beautifully Can you use pre and post at same time? Playful, I do have a question about understanding the '(([^.<]*?\.?)*))\.gh' part of your regex to match '01.jpg</a>' Translation: "(([not including any character <] zero or more times)maybe)any character maybe)zero or more times).gh" Question: Where is my translation wrong because you need to say something like ([not including any character]one or more times)<\/a>\.gh)" right? Thank you again for your help!

Hey! I was wondering if you can specify something like below or if you would have to use two different regex's I am trying to match only the .gh files below by saying: /http:\/\/www.grasshopper3d.com\/forum\/attachment\/download\?id=2985220%3AUploadedFile%3A[0-9]{6}[^.+\.gh]/ meaning include the files that are .gh files but don't include the .gh in the match. (ie. exclude the .jpg, etc files) Data: "http://www.grasshopper3d.com/forum/attachment/download?id=2985220%3AUploadedFile%3A501843">01.jpg</a> "http://www.grasshopper3d.com/forum/attachment/download?id=2985220%3AUploadedFile%3A506981">SURFACE-DIAGRID-TEST.gh</a> Thank you! McK

Got it! Thank you so much! McK

Okay. Thank you. When I run the code and have it echo an item in the array it only prints 'Array' to the screen. I tried converting it to a string via implode and accessing the array with an index but it still just prints 'Array' to the screen. <?PHP if(isset($_POST['Store'])) { $mainUrl = 'http://www.grasshopper3d.com/forum/categories/sample-and-example-files/listForCategory'; //search for all URLs with www.grasshopper3d/forum/topics/bla preg_match_all("/discussion./", $mainUrl, $urlMatches); $fileName = "urls.txt"; $urlFile = fopen($fileName, 'w') or die("Cant open file"); echo('matches: '. $urlMatches[0]); //fwrite($urlFile, $urlMatches) or die("Cant write to file"); } ?>

Hey guys! I am trying to find matches to discussions in a text file and am getting the error Warning: preg_match_all() [function.preg-match-all]: Delimiter must not be alphanumeric or backslash in C:\xampp\htdocs\mywebsite\temp1.php on line 6 Cant write to file <?PHP if(isset($_POST['Store'])) { $mainUrl = 'http://www.grasshopper3d.com/forum/categories/sample-and-example-files/listForCategory'; //search for all URLs with www.grasshopper3d/forum/topics/bla preg_match_all("discussion.", $mainUrl, $urlMatches); $fileName = "urls.txt"; $urlFile = fopen($fileName, 'w') or die("Cant open file"); fwrite($urlFile, $urlMatches) or die("Cant write to file"); } ?> Can someone please help me figure out why?
