  • Replacing values using preg_replace

    - by Jeepstone
    I have a Joomla plugin (not important in this context), which is designed to take an input with a load of numbers (within a paragraph of text) and replace them with a series of s. My problem is that I need to do a preg_replace on my $article-text, but I don't know how to then apply the changes to the matched terms. I've seen the preg_replace_callback, but I don't know how I can call that within a function. function onPrepareContent( &$article, &$params, $limitstart ) { global $mainframe; // define the regular expression $pattern = "#{lotterynumbers}(.*?){/lotterynumbers}#s"; if(isset($article->text)){ preg_match($pattern, $article->text, $matches); $numbers = explode("," , $matches[1]); foreach ($numbers as $number) { echo "<div class='number'><span>" . $number . "</span></div>"; } }else{ $article->text = 'No numbers'; } return true; } AMENDED CODE: function onPrepareContent( &$article, &$params, $limitstart ) { global $mainframe; // define the regular expression $pattern = "#{lotterynumbers}(.*?){/lotterynumbers}#s"; if(isset($article->text)){ preg_match($pattern, $article->text, $matches); $numbers = explode("," , $matches[1]); foreach ($numbers as $number) { $numberlist[] = "<div class='number'><span>" . $number . "</span></div>"; } $numberlist = implode("", $numberlist); $article->text = preg_replace($pattern, $numberlist, $article->text); }else{ $article->text = 'No numbers'; } return true; }

  • How do I locate a particular word in a text file using C#

    - by cmrhema
    Hi, I am sending mails (in asp.net ,c#), having a template in text file (.txt) like below User Name :<User Name> Address : <Address>. I used to replace the words within the angle brackets in the text file using the below code StreamReader sr; sr = File.OpenText(HttpContext.Current.Server.MapPath(txt)); copy = sr.ReadToEnd(); sr.Close(); //close the reader copy = copy.Replace(word.ToUpper(),"#" + word.ToUpper()); //remove the word specified UC //save new copy into existing text file FileInfo newText = new FileInfo(HttpContext.Current.Server.MapPath(txt)); StreamWriter newCopy = newText.CreateText(); newCopy.WriteLine(copy); newCopy.Write(newCopy.NewLine); newCopy.Close(); Now I have a new problem, the user will be adding new words within an angle, say for eg, they will be adding <Salary>. In that case i have to read out and find the word <Salary>. In other words, I have to find all the words, that are located with the angle brackets (<). How do I do that. Kindly do let me know. Thanks.

  • Can mod_rewrite do math?

    - by ewall
    I am planning to convert my website to a new CMS, but I would like to use mod_rewrite to seamlessly redirect old links to their new locations. The catch is that my new blog will not have the same article numbers as the old, because I'll import some older blog entries in their first. Thus, my mod_rewrite would need to take a URL like old.php?article=125, do the addition to figure out the new article number (say +200, for this example), and redirect to new.php?i=325. Can mod_rewrite do the addition on its own, or am I going to need some kind of 'helper' script to do that?

  • Regex to add CDATA for mal formed XML

    - by AntonioCS
    Hey guys! I have this huge xml file (13 mb) and it has some malformed values. Here is a sample of the xml: <propertylist> <adprop index="0" proptype="type" value="Ft"/> <adprop index="0" proptype="category" value="Bs"/> <adprop index="0" proptype="subcategory" value="Bsm"/> <adprop index="0" proptype="description" value="MOONEN CUSTOM 58"/> </propertylist> Now this is ok. But I many other nodes that are not encapsulated in CDATA that need to be. The node that gives me problems is the <adprop index="0" proptype="description" value=""/> I created this regular expression: <adprop index="0" proptype="description" value="(.+)"\/> to catch that node and replace it with this: <adprop index="0" proptype="description" value="<![CDATA[\1]]>"\/> I run this in notepad++ and it works. The only problem is when the value="" is multi lined like: <adprop index="0" proptype="description" value="cutter that has demonstrated her offshore capabiliti from there to the Canaries with her current owner. Spacious homely interior with over 2m headroom and heaps of" /> It fails with this one, and there are plenty like this one. Can anyone help me out in the regular expression so that I can catch the value when it's multi lined? Thanks

  • Perl Regex - Condensing groups of find/replace

    - by brydgesk
    I'm using Perl to perform some file cleansing, and am running into some performance issues. One of the major parts of my code involves standardizing name fields. I have several sections that look like this: sub substitute_titles { my ($inStr) = @_; ${$inStr} =~ s/ PHD./ PHD /; ${$inStr} =~ s/ P H D / PHD /; ${$inStr} =~ s/ PROF./ PROF /; ${$inStr} =~ s/ P R O F / PROF /; ${$inStr} =~ s/ DR./ DR /; ${$inStr} =~ s/ D.R./ DR /; ${$inStr} =~ s/ HON./ HON /; ${$inStr} =~ s/ H O N / HON /; ${$inStr} =~ s/ MR./ MR /; ${$inStr} =~ s/ MRS./ MRS /; ${$inStr} =~ s/ M R S / MRS /; ${$inStr} =~ s/ MS./ MS /; ${$inStr} =~ s/ MISS./ MISS /; } I'm passing by reference to try and get at least a little speed, but I fear that running so many (literally hundreds) of specific string replaces on tens of thousands (likely hundreds of thousands eventually) of records is going to hurt the performance. Is there a better way to implement this kind of logic than what I'm doing currently? Thanks Edit: Quick note, not all the replace functions are just removing periods and spaces. There are string deletions, soundex groups, etc.

  • Python re.IGNORECASE being dynamic

    - by Adam Nelson
    I'd like to do something like this: re.findall(r"(?:(?:\A|\W)" + 'Hello' + r"(?:\Z|\W))", 'hello world',re.I) And have re.I be dynamic, so I can do case-sensitive or insensitive comparisons on the fly. This works but is undocumented: re.findall(r"(?:(?:\A|\W)" + 'Hello' + r"(?:\Z|\W))", 'hello world',1) To set it to sensitive. Is there a Pythonic way to do this? My best thought so far is: if case_sensitive: regex_senstive = 1 else: regex_sensitive = re.I re.findall(r"(?:(?:\A|\W)" + 'Hello' + r"(?:\Z|\W))", 'hello world',regex_sensitive)

  • Regular expressions and matching question marks in URLs

    - by James P.
    I'm having trouble finding a regular expression that matches the following String. Korben;http://feeds.feedburner.com/KorbensBlog-UpgradeYourMind?format=xml;1 One problem is escaping the question mark. Java's pattern matcher doesn't seem to accept \? as a valid escape sequence but it also fails to work with the tester at myregexp.com. Here's what I have so far: ([a-zA-Z0-9])+;http://([a-zA-Z0-9./-]+);[0-9]+ Any suggestions?

  • jQuery element with multiple classes: storing one class as a var

    - by Aaron
    I'm trying to create a standardized show/hide element system, like so: <div class="opener popup_1">Click Me</div> <div class="popup popup_1">I'm usually hidden</div> Clicking on the div with the opener class should show() the div with the popup class. I don't know how many opener/popup combinations I'm going to have on any given page, I don't know where on any given page the opener and the popup are going to be displayed, and I don't know how many popups a given opener should call show() for. Both the opener and the popup have to be able to have more classes than just what's used by jQuery. What I'd like to do is something like this: $(".opener").click(function() { var openerTarget = $(this).attr("class").filter(function() { return this.class.match(/^popup_([a-zA-Z0-9-_\+]*) ?$/); }); $(".popup." + openerTarget).show(); The idea is that when you click on an opener, it filters out "popup_whatever" from opener's classes and stores that as openerTarget. Then anything with class=popup and openerTarget will be shown.

  • ack (perl?) regexp matching lines where if is the first word

    - by Gauthier
    Hey. I'm finally learning regexps, training with ack. I believe this uses perl regexp. I want to match all lines where the first non-blank characters are if (<word> !, with any number of spaces in between the elements. This is what I came up with: ^[ \t]*if *\(\w+ *! It only nearly worked. ^[ \t]* is wrong, since it matches one or none [space or tab]. What I want is to match anything that may contain only space or tab (or nothing). For example these should not match: // if (asdf != 0) else if (asdf != 1) How can I modify my regexp for that?

  • I'm trying to use a regular expression to retrieve text from RichTextBox

    - by Simon
    Hello! As the header is implying I'm trying to retrieve a certain line of numbers from a richtextbox and then put it into a separate textbox. I've tried this code below but it doesn't wanna work with me. It's probably way wrong and there's probably easier ways of doing it but I'm quite new to this stuff and I would appreciate all the help I can get in this matter. I have a textbox called tbPersNr; A RichTextBox called tbText; A button which is called btnGet; string regPattern = @"\\d{6}-\\d{4}"; int indexOfSearch = 0; private void btnGet_Click(object sender, EventArgs e) { int startIndex = 0; if (tbText.Text.Length > 0) { startIndex = HittaPersNr(regPattern, startIndex, tbText.Text.Length); } if (startIndex > 0) { this.tbPersNr.Text = regPattern.ToString(); } } public int HittaPersNr(string txtToSearch, int searchStart, int searchEnd) { // Setting default value to -1. int retVal = -1; // Validating start of the search // om indexOfSearch = -1, slutar sökningen if (searchStart >= 0 && indexOfSearch >= 0) { // Validating end of search if (searchEnd > searchStart || searchEnd == -1) { // Searching for results in richtextbox indexOfSearch = tbText.Find(regPattern, searchStart, searchEnd, RichTextBoxFinds.None); // Validating if search resulted in any finds. if (indexOfSearch != -1) { // putting index to value in the text. retVal = indexOfSearch; } } } return retVal; } } } Cheers

  • PHP script loading took over 10 seconds

    My again. I've promised to not come back today, but I've got another trouble. http://www.misiur.com/me/ - it took over 10 seconds to load. Whole site code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="pl" lang="pl"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>{site('title')}</title> <link rel="stylesheet" type="text/css" href="{site('themeDir')}/global.css" /> </head> <body> <div id="site"> <div id="footer"> <p>Site Managment System {site('version')} by <a href="http://www.misiur.com">Misiur</a>.

I think that I've messed up. Help.

  • Regexp to extract sources from different video embeds

    - by Ben
    My SMF forum contains posts with video and I want to extract them to show on the Wordpress main page. My current regexp (thanks to SO!) extracts the url of the videos, which I embed using AutoEmbed. Everything works up until a post looks like this: <embed height="600" width="600" allowscriptaccess="never" quality="high" loop="true" play="true" src="http://mmavlog.net/embed/player.swf?file=http://video.ufc.tv/CSG/UFC113/20100507_ufc113_weigh_in_400k.flv" type="application/x-shockwave-flash"> Here is my current regexp: $regexp = "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i"; Since the posts can contain <embed> or <object> I realize that looking for the url by the "http" might be inaccurate. How can I use the regexp to look for "src=" for <embed> and "data=" for <object>?

  • Backslash escaping in RegularExpressionValidator

    - by frogbot
    I need to ensure that the input value contains at least one dot, so i use the following: <asp:RegularExpressionValidator runat="server" ControlToValidate="MyInput" Text="*" ErrorMessage="must contain at least one dot" ValidationExpression="\.+" /> And that doesn't work. By inspecting the page source i can see that ASP.NET escapes the backslash character so in java-script it looks like "\\.+". Why does it do so and how do i prevent RegularExpressionValidator from escaping it?
