  • Perl Search and Replace Avoid Variable Interpolation

    - by Justin
    I'm really getting my butt kicked here. I can not figure out how to write a search and replace that will properly find this string. String: $QData{"OrigFrom"} $Text{"wrote"}: Note: That is the actual STRING. Those are NOT variables. I didn't write it. I need to replace that string with nothing. I've tried escaping the $, {, and }. I've tried all kinds of combinations but it just can't get it right. Someone out there feel like taking a stab at it? Thanks!

  • Convert Javascript Regular Expression to PHP (PCRE) Expression

    - by Matt
    Hi all, I am up to my neck in regular expressions, and I have this regular expression that works in javascript (and flash) that I just can't get working in PHP Here it is: var number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; var oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]' + '|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; var str = '(?:\"' + oneChar + '*\")'; var varName = '\\$(?:' + oneChar + '[^ ,]*)'; var func = '(?:{[ ]*' + oneChar + '[^ ]*)'; // Will match a value in a well-formed JSON file. // If the input is not well-formed, may match strangely, but not in an unsafe // way. // Since this only matches value tokens, it does not match whitespace, colons, // or commas. var jsonToken = new RegExp( '(?:false|true|null' +'|[\\}]' + '|' + varName + '|' + func + '|' + number + '|' + str + ')', 'g'); If you want it fully assembled here it is: /(?:false|true|null|[\}]|\$(?:(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ,]*)|(?:{[ ]*(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ]*)|(?:-?\b(?:0|[1-9][0-9]*)(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\b)|(?:"(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))*"))/g Interestingly enough, its very similar to JSON. I need this regular expression to work in PHP... Here's what I have in PHP: $number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; $oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; $string = '(?:\"'.$oneChar.'*\")'; $varName = '\\$(?:'.$oneChar.'[^ ,]*)'; $func = '(?:{[ ]*'.$oneChar.'[^ ]*)'; $jsonToken = '(?:false|true|null' .'|[\\}]' .'|'.$varName .'|'.$func .'|'.$number .'|'.$string .')'; echo $jsonToken; preg_match_all($jsonToken, $content, $out); return $out; Here's what happens if I try using preg_match_all(): Warning: preg_match_all() [function.preg-match-all]: Compilation failed: nothing to repeat at offset 0 in /Users/Matt/Sites/Templating/json/Jeeves.php on line 88 Any help would be much appreciated!

  • Javascript/Greasemonkey: search for something then set result as a value

    - by thewinchester
    Ok, I'm a bit of a n00b when it comes to JS (I'm not the greatest programmer) so please be gentle - specially if my questions been asked already somewhere and I'm too stupid to find the right answer. Self deprecation out of the way, let's get to the question. Problem There is a site me and a large group of friends frequently use which doesn't display all the information we may like to know - in this case an airline bookings site and the class of travel. While the information is buried in the code of the page, it isn't displayed anywhere to the user. Using a Greasemonkey script, I'd like to liberate this piece of information and display it in a suitable format. Here's the psuedocode of what I'm looking to do. Search dom for specified element define variables Find a string of text If found Set result to a variable Write contents to page at a specific location (before a specified div) If not found Do nothing I think I've achieved most of it so far, except for the key bits of: Searching for the string: The page needs to search for the following piece of text in the page HEAD: mileageRequest += "&CLASSES=S,S-S,S-S"; The Content I need to extract and store is between the second equals (=) sign and the last comma ("). The contents of this area can be any letter between A-Z. I'm not fussed about splitting it up into an array so I could use the elements individually at this stage. Writing the result to a location: Taking that found piece of text and writing it to another location. Code so far This is what I've come up so far, with bits missing highlighted. buttons = document.getElementById('buttons'); ''Search goes here var flightClasses = document.createElement("div"); flightClasses.innerHTML = '<div id="flightClasses"> ' + '<h2>Travel classes</h2>' + 'For the above segments, your flight classes are as follows:' + 'write result here' + '</div>'; main.parentNode.insertBefore(flightClasses, buttons); If anyone could help me, or point me in the right direction to finish this off I'd appreciate it.

  • Alternative for my preg_replace code

    - by Ben Sinclair
    Here is my code... basically it finds any page-NUMBER- within a variable and then replaces it with a page url from an array $content_text = preg_replace("/page-(\d+)-/sie", '$pageurl[$1]', $content_text); It works a treat until the NUMBER it finds isn't in the array and it returns an error... Is there another efficient way I could do this instead? I liked my code above because it was simple but I may have to use more complex code...

  • 301 htaccess redirect: add segment to old URL's

    - by Rick
    I'm trying to make sure old url's aren't broken after the site's URL structure has changed from this: http://www.domain.com/section/entry_name to this: http://www.domain.com/section/event_name/entry_name But to make it a bit more complex, I'm using the segments to sort entries, for example: http://www.domain.com/news/amazing_event/date/asc http://www.domain.com/videos/my_event/title/desc The new structure only effects one particular event (amazing_event) and should leave the other URL's alone. Where do I even begin to tackle this? My current .htaccess looks like: RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ /index.php/$1 [L] Thanks - appreciate any tips.

  • Validate a string in a table in SQL Server - CLR function or T-SQL

    - by Ashish Gupta
    I need to check If a column value (string) in SQL server table starts with a small letter and can only contain '_', '-', numbers and alphabets. I know I can use a SQL server CLR function for that. However, I am trying to implement that validation using a scalar UDF and could make very little here...I can use 'NOT LIKE', but I am not sure how to make sure I validate the string irrespective of the order of characters or in other words write a pattern in SQL for this. Am I better off using a SQL CLR function? Any help will be appreciated.. Thanks in advance Thank you everyone for their comments. This morning, I chose to go CLR function way. For the purpose of what I was trying to achieve, I created one CLR function which does the validation of an input string and have that called from a SQL UDF and It works well. Just to measure the performance of t-SQL UDF using SQL CLR function vs t- SQL UDF, I created a SQL CLR function which will just check if the input string contains only small letters, it should return true else false and have that called from a UDF (IsLowerCaseCLR). After that I also created a regular t-SQL UDF(IsLowerCaseTSQL) which does the same thing using the 'NOT LIKE'. Then I created a table (Person) with columns Name(varchar) and IsValid(bit) columns and populate that with names to test. Data :- 1000 records with 'Ashish' as value for Name column 1000 records with 'ashish' as value for Name column then I ran the following :- UPDATE Person Set IsValid=1 WHERE dbo.IsLowerCaseTSQL (Name) Above updated 1000 records (with Isvalid=1) and took less than a second. I deleted all the data in the table and repopulated the same with same data. Then updated the same table using Sql CLR UDF (with Isvalid=1) and this took 3 seconds! If update happens for 5000 records, regular UDF takes 0 seconds compared to CLR UDF which takes 16 seconds! I am very less knowledgeable on t-SQL regular expression or I could have tested my actual more complex validation criteria. But I just wanted to know, even I could have written that, would that have been faster than the SQL CLR function considering the example above. Are we using SQL CLR because we can implement we can implement lot richer logic which would have been difficult otherwise If we write in regular SQL. Sorry for this long post. I just want to know from the experts. Please feel free to ask if you could not understand anything here. Thank you again for your time.

  • Python regular expressions matching variables to end of line

    - by None
    When you use variables (is that the correct word?) in python regular expressions like this: "blah (?P\w+)" ("value" would be the variable), how could you make the variable's value be the text after "blah " to the end of the line or to a certain character not paying any attention to the actual content of the variable. For example, this is pseudo-code for what I want: >>> import re >>> p = re.compile("say (?P<value>continue_until_text_after_assignment_is_recognized) endsay") >>> m = p.match("say Hello hi yo endsay") >>> m.group('value') 'Hello hi yo' Note: The title is probably not understandable. That is because I didn't know how to say it. Sorry if I caused any confusion.

    - by PeterTheNiceGuy
    I am new to JQuery and am using the JQuery validation plugin. Great stuff! I want to migrate my existing ASP.NET solution to use JQuery instead of the ASP.NET validators. I am missing a replacement for the regular expression validator. I want to be able to do something like this: $("Textbox").rules("add", { regularExpression: "^[a-zA-Z'.\s]{1,40}$" }) Could anyone give me a hint how to add a custom rule to achieve this?

  • Convert Plain Text Hyperlinks into HTML Hyperlinks in PHP

    I have a simple commenting system here... http://affbuzz.com/comments/7299a55137def55917a5dc6c4fe0f261af8a4217 ...and people can submit hyperlinks inside the plain text field. When I display these records back from the database and into the web page, what RegExp in PHP can I use to convert these links into HTML-type anchor links? Bonus: For the algorithm to not do this with any other kind of link, just http and https.

  • Awk to grab colo(u)r codes from CSS files aka School me in Awk

    - by Andrew Bolster
    Nice and (hopefully) easy. I am trying to work out how to grab the variable #XXX from a text file (css file) containing strings like hr { margin: 18px 0 17px; border-color: #ccc; } h1 a:hover, h2 a:hover, h3 a:hover { color: #001100; } Which I would like to return as ccc 777 The plan then is to throw this through sort and uniq and the end up with a defining colourscheme for the page. Basically, I can't work out how to go from matching /color:#...[...]/ to just printing out the wildcarded sections.

  • RegEXP Javascript URL matching

    - by Blondie
    I have this so far: chrome.tabs.getSelected(null, function(tab) { var title = tab.title; var btn = '<a href="' + tab.url + '" onclick="save(\'' + title + '\');"> ' + title + '</a>'; if(RegExp('/http:\/\/www.mydomain.com\/version.php/i') == true) { document.getElementById('link').innerHTML = '<p>' + btn + '</p>'; } }); Basically it should match the domain within this: http://www.mydomain.com/version.php?* Anything that matches that even when it includes something like version.php?ver=1, etc When I used the code above of mine, it doesn't display anything, but when I remove the if statement, it's fine but it shows on other pages which it shouldn't only on the matched URL.

  • Converting John Resig's Templating Engine to work with PHP Templates

    - by Serhiy
    I'm trying to convert the John Resig's new ASP.NET Templating Engine to work with PHP. Essentially what I would like to achieve is the ability to use certain Kohana Views via a JavaScript templating engine, that way I can use the same views for both a standard PHP request and a jQuery AJAX request. I'm starting with the basics and would like to be able to convert http://github.com/nje/jquery-tmpl/blob/master/jquery.tmpl.js To work with php like so... <li><a href="{%= link %}">{%= title %}</a> - {%= description %}</li> <li><a href="<?= $link ?>"><?= $title ?></a> - <?= description ?></li> The RexEx in it is a bit over my head and it's apparently not as easy as changing the %} to ? in lines 148 to 158. Any help would be highly appreciated. I'm also not sure of how to take care of the $ difference that PHP variables have. Thanks, Serhiy

  • Lua pattern matching vs. regular expressions

    hello, i'm currently learning lua. regarding pattern-matching in lua i found the following sentence in the lua documentation on lua.org: Nevertheless, pattern matching in Lua is a powerful tool and includes some features that are difficult to match with standard POSIX implementations. as i'm familiar with posix regular expressions i would like to know if there are any common samples where lua pattern matching is "better" compared to regular expression -- or did i misinterpret the sentence? and if there are any common examples: why is any of pattern-matching vs. regular expressions better suited? thanks very much, harald

  • Using regular expressions to remove relative path slashes

    - by Adam Carlile
    Hey Guys I am trying to remove all the relative image path slashes from a chunk of HTML that contains several other elements. For example <img src="../../../../images/upload/1/test.jpg /> would need to become <img src="http://s3.amazonaws.com/website/images/upload/1/test.jpg" /> I was thinking of writing this as a rails helper, and just passing the entire block into the method, and make using Nokogiri or Hpricot to parse the HTML instead, but I don't really know. Any help would be great Cheers Adam
