  • How to write a regular expression for "everything between X and Y" for use with preg_replace

    - by pg
    I want to take a variable called $encoded_str and and remove cd1, CD1 and anything between the first 'l' and the last blank space. So for example "lp6 id4 STRINGcd1" would return "STRING". I'm using PHP 4 for now so I can't use str_ireplace, I have this: $encoded_str=str_replace('CD1','',$encoded_str); $encoded_str=str_replace('cd1','',$encoded_str); $encoded_str=preg_replace('X','',$encoded_str); I've RTFM for preg_replace but am a bit confused. What should I replace the X with and can you suggest a decent introductory primer for writing regular expressions?

  • How do I extract info from a block of URLs in php?

    - by Jack
    I have a list of urls, which can come in any format. One per line, separated by commas, have random text in between them, etc. the URLs are all from 2 different sites, and have a similar structure For this example, lets say it looks like this Random Text - http://www.domain2.com/variable-value Random Text 2 - http://www.domain1.com/variable-value, http://www.domain1.com/variable-value, http://www.domain1.com/variable-value http://www.domain1.com/variable-value http://www.domain2.com/variable-value http://www.domain1.com/variable-value http://www.domain2.com/variable-value http://www.domain1.com/variable-value I need to extract 2 pieces of information. Check to see if its domain1 or domain2 and the value that follows "variable-" So it should create a multi-dimensional array, which would have 2 items: domain + value. Whats the best way of doing that?

  • negative look ahead to exclude html tags

    - by Remoh
    I'm trying to come up with a validation expression to prevent users from entering html or javascript tags into a comment box on a web page. The following works fine for a single line of text: ^(?!.(<|)).$ ..but it won't allow any newline characters because of the dot(.). If I go with something like this: ^(?!.(<|))(.|\s)$ it will allow multiple lines but the expression only matches '<' and '' on the first line. I need it to match any line. This works fine: ^[-_\s\d\w"'.,:;#/&\$\%\?!@+*\()]{0,4000}$ but it's ugly and I'm concerned that it's going to break for some users because it's a multi-lingual application. Any ideas? Thanks!

  • [AS 3.0] How to use the string.match method to find multiple occurrences of the same word in a strin

    - by Steven
    In Actionscript and Adobe Flex, I'm using a pattern and regexp (with the global flag) with the string.match method and it works how I'd like except when the match returns multiple occurrences of the same word in the text. In that case, all the matches for that word point only to the index for the first occurrence of that word. For example, if the text is "cat dog cat cat cow" and the pattern is a search for cat*, the match method returns an array of three occurrences of "cat", however, they all point to only the index of the first occurrence of cat when i use indexOf on a loop through the array. I'm assuming this is just how the string.match method is (although please let me know if i'm doing something wrong or missing something!). I want to find the specific indices of every occurrence of a match, even if it is of a word that was already previously matched. I'm wondering if that is just how the string.match method is and if so, if anyone has any idea what the best way to do this would be. Thanks.

  • Pulling international street addresses / phone numbers from free-form text

    - by spitzanator
    Hey, folks. I'm looking for some regular expressions to help grab street addresses and phone numbers from free-form text (a la Gmail). Given some text: "John, I went to the store today, and it was awesome! Did you hear that they moved to 500 Green St.? ... Give me a call at +14252425424 when you get a chance." I'd like to be able to pull out: 500 Green St. (recognized as a street address) +14252425424 (recognized as a phone number) What makes this problem easier is that I don't care about parsing text that gets pulled out. That is, I don't care that Green is the name of the road or that 425 is the area code. I just want to grab strings that "look like" addresses or telephone numbers. Unfortunately, this needs to work internationally, as best as possible. Anyone have any leads? Thanks!

  • Get main article image with PHP

    - by PaulAdamDavis
    Hello! I'd like to get the main image for an article, much like Facebook does when you post a link (but without the choosing image part). The data we have to work with is the whole pages HTML as a variable. The page & URL will be different for every time this function runs. Are there any libraries or classes that are particularly good at getting the main body of content, much like Instapaper that would be of any help?

  • Function of: if(/(file|http).*/.test(url)) { }

    - by WmasterJ
    I am wondering what this technique is called and what it does. It seems to be validating some regular expression on the variable url. I am customizing another persons code: var url = document.getElementById("editorURL").value; if(/(file|http).*/.test(url)) { } Maybe someone has a link to an article that explains this a bit more in-depth?

  • Simple Search and Replace use of Regular Expression

    - by nunos
    So, I am adapting some code I found online to suit my needs. However, my set_pixel function has two more parameters. Since there are lots of calls to this function even doing a quick paste over would be very tedious. So, I thought this would be a good time for me to learn some simple regular expressions. So, I have calls of this type: set_pixel(arg1, arg2); which I want to change to something like: set_pixel(arg1, arg2, arg3, arg4); Note: arg1 and and 2 should be preserved, whereas arg3 and arg4 are most of the time the same. How can I achieve this?

    I'm trying to use sed to replace whitespace within a string. For example, given the line: var test = 'Some test text here.'; I want to get: var test = 'Sometesttexthere.'; I've tried using (\x27 matches the '): sed 's|\x27\([^x27[:space:]]*\)[[:space:]]|\x27\1|g but that just gives var test = 'Sometest text here.'; Any ideas?

    I want to write a fuction like that: - Input: "1" -> return : "1" - Input: "12" -> return : ["1","2"] If I use the function split(): String.valueOf("12").split("") -> ["","1","2"] But, I only want to get the result: ["1","2"].

Infact, I can do that: private List<String> decomposeQuantity(final int quantity) { LinkedList<String> list = new LinkedList<String>(); int parsedQuantity = quantity; while (parsedQuantity > 0) { list.push(String.valueOf(parsedQuantity % 10)); parsedQuantity = parsedQuantity / 10; } return list; } But, I want to use split() for having an affective code
