  • Regex: How to leave out webding font characters?

    - by DS
    Hi, I've a free text field on my form where the users can type in anything. Some users are pasting text into this field from Word documents with some weird characters that I don't want to go in my DB. (e.g. webding font characters) I'm trying to get a regular expression that would give me only the alphanum and the punctuation characters. But when I try the following, the output is still all the characters. How can I leave them out? <html><body><script type="text/javascript">var str="???????";document.write(str.replace(/[^a-zA-Z 0-9 [:punct]]+/g, " "));</script></body></html>

  • Is there a way to optimise finding text items on a page (not regex)

    - by Jeepstone
    After seeing several threads rubbishing the regexp method of finding a term to match within an HTML document, I've used the Simple HTML DOM PHP parser (http://simplehtmldom.sourceforge.net/) to get the bits of text I'm after, but I want to know if my code is optimal. It feels like I'm looping too many times. Is there a way to optimise the following loop? //Get the HTML and look at the text nodes $html = str_get_html($buffer); //First we match the <body> tag as we don't want to change the <head> items foreach($html->find('body') as $body) { //Then we get the text nodes, rather than any HTML foreach($body->find('text') as $text) { //Then we match each term foreach ($terms as $term) { //Match to the terms within the text nodes $text->outertext = str_replace($term, '<span class="highlight">'.$term.'</span>', $text->outertext); } } } For example, would it make a difference to determine check if I have any matches before I start the loop maybe?

  • Regex get multiple segments of a string in javascript

    - by dave
    I'm trying to extract some results from a download manager, the format is: [#8760e4 4.3MiB/40MiB(10%) CN:2 DL:4.9MiB ETA:7s] what I'd like to extract from the above example, would be an array that looks like this: ['4.3','MiB','40','MiB','10%','4.9','MiB','7','s'] I've tried to split this in various combinations, but nothing seems to be right. Would anyone happen to know how to do this or be able to offer suggestions? Thank you!

  • Prevent RegEx Hang on Large Matches...

    - by developerjay
    This is a great regular expression for dates... However it hangs indefinitely on this one page I tried... I wanted to try this page ( http://pleac.sourceforge.net/pleac%5Fpython/datesandtimes.html ) for the fact that it does have lots of dates on it and I want to grab all of them. I don't understand why it is hanging when it doesn't on other pages... Why is my regexp hanging and/or how could I clean it up to make it better/efficient ? Python Code: monthnames = "(?:Jan\w*|Feb\w*|Mar\w*|Apr\w*|May|Jun\w?|Jul\w?|Aug\w*|Sep\w*|Oct\w*|Nov(?:ember)?|Dec\w*)" pattern1 = re.compile(r"(\d{1,4}[\/\\\-]+\d{1,2}[\/\\\-]+\d{2,4})") pattern4 = re.compile(r"(?:[\d]*[\,\.\ \-]+)*%s(?:[\,\.\ \-]+[\d]+[stndrh]*)+[:\d]*[\ ]?(PM)?(AM)?([\ \-\+\d]{4,7}|[UTCESTGMT\ ]{2,4})*"%monthnames, re.I) patterns = [pattern4, pattern1] for pattern in patterns: print re.findall(pattern, s) btw... when i say im trying it against this site.. I'm trying it against the webpage source.

  • regex no character

    - by iamnotmad
    In this text: warning here there are several types of warnings in this string warning.gif at the end warning end of line warning I want to match every warning except warning.gif. I cannot seem to get it to include the last one that has no character (control or otherwise) after it. using warnings?[^\.] gets what I want except for the last warning (on the last line). I think because there is no character at all after. How can I get it to include that one?

  • Regex if-else expression

    - by craig
    I'm trying to extract the # of minutes from a text field using Oracle's REGEXP_SUBSTR() function. Data: Treatment of PC7, PT1 on left. 15 min. 15 minutes. 15 minutes 15 mins. 15 mins 15 min. 15 min 15min 15 In each case, I'm hoping to extract the '15' part of the string. Attempts: \d+ gets all of the numeric values, including the '7' and '1', which is undesirable. (\d)+(?=\ ?min) get the '15' from all rows except the last. (?((\d)+(?=\ ?min))((\d)+(?=\ ?min))|\d+), an if-else statement, doesnt' match anything. What is wrong with my if-else statement?

  • Need Regex for to match special situations

    - by Daniel
    I'm desperately searching for regular expressions that match these scenarios: 1) Match alternating chars I've a string like "This is my foobababababaf string" - and I want to match "babababa" Only thing I know is the length of the fragment to search - I don't know what chars/digits that might be - but they are alternating. I've really no clue where to start :( 2) Match combined groups In a string like "This is my foobaafoobaaaooo string" - and I want to match "aaaooo". Like in 1) I don't know what chars/digits that might be. I only know that they will appear in two groups. I experimented using (.)\1\1\1(.)\1\1\1 and things like this...
