  • 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

    - by dexter
    i have array which values are user input like: aa df rrr5 4323 54 hjy 10 gj @fgf %d would be that array, now i want to check each value in array whether its numeric or alphabetic (a-zA-Z) or alphanumeric and save them in other respective arrays i have done: my @num; my @char; my @alphanum; my $str =<>; my @temp = split(" ",$str); foreach (@temp) { print "input : $_ \n"; if ($_ =~/^(\d+\.?\d*|\.\d+)$/) { push(@num,$_); } } this works, similarly i want to check for alphabet, and alphanumeric values note: alphanumeric ex. fr43 6t$ $eed5 *jh

  • 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?

  • 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?

  • 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)

  • Filtering out emoticons using sed

    - by user349222
    Hello, I have a grep expression using cygwin grep on Win. grep -a "\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u" all_fbs.txt > rockon_fbs.txt Once I identify the emoticon class, however, I want to strip them out of the data. However, the same regexp above within a sed results in a syntax error (yes, I realize I could use /d instead of //g, but this doesn't make a difference, I still get the error.) sed "s/\(\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u\)*//g" The full line is: grep -a "\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u" all_fbs.txt | sed "s/\(\\,,/\|\\m/\|\\m/\\>\.</\\m/\|:u\)*//g" | sed "s/^/ROCKON\t/" > rockon_fbs.txt The result is: sed: -e expression #1, char 14: unknown option to `s' I know it's coming from the sed regexp I'm asking about it b/c if I remove that portion of the full line, then I get no error (but, of course, the emoticons are not filtered out). Thanks in advance, Steve

  • 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.

  • Apache RewriteRule: it is possible to 'detect' the first and second path segment?

    - by DaNieL
    Im really really a newbie in regexp and I can’t figure out how to do that. My goal is to have the RewriteRule to 'slice' the request URL path in 3 parts: example.com/foo #should return: index.php?a=foo&b=&c= example.com/foo/bar #should return: index.php?a=foo&b=bar&c= example.com/foo/bar/baz #should return: index.php?a=foo&b=bar&c=baz example.com/foo/bar/baz/bee #should return: index.php?a=foo&b=bar&c=baz/bee example.com/foo/bar/baz/bee/apple #should return: index.php?a=foo&b=bar&c=baz/bee/apple example.com/foo/bar/baz/bee/apple/and/whatever/else/no/limit/in/those/extra/parameters #should return: index.php?a=foo&b=bar&c=baz/bee/apple/and/whatever/else/no/limit/in/those/extra/parameters In short, the first segment in the URL path (foo) should be given to a, the second segment (bar) to b, and the rest of the string in c I wroted this one <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !=/favicon.ico RewriteRule ^(([a-z0-9/]))?(([a-z0-9/]+))?(([a-z0-9]+))(.*)$ index.php?a=$1&b=$2&c=$3 [L,QSA] </IfModule> But obviously doesn’t work, and I don’t even know if what I want is possible. Any suggestion? EDIT: After playing with coach manager, I got this one working too: RewriteRule ^([^/]*)?/?([^/]*)?/?(.*)?$ index.php?a=$1&b=$2&c=$3 [L,QSA]

  • 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

  • Regular expression to match one of two video ID's in a Google Video URL

    - by Baldur
    I need to grab the video ID from a Google Video URL. There are two different types of URLs that I need to be able to match: http://video.google.com/videoplay?docid=-3498228245415745977# where I need to be able to match -3498228245415745977 (note the dash; -), and video.google.com/videoplay?docid=-3498228245415745977#docid=2728972720932273543 where I need to match 2728972720932273543. Is there any good regular expression that can match this? This is what I've got so far: @"docid=(-?\d{19}+)" since the video ID seems to be 19 characters except when it's prefixed with the dash. I'm using C# (of which I have very little experience) if that changes anything. P.s. I would also appreciate you review my regular expressions for YouTube (@"[\?&]v=([^&#])";), RedTube (@"/(\d{1,6})") and Vimeo (@"/(\d*)"). I do not expect users to enter the full URL and thus do not match the ^http://\\.?sitename+\\.\\w{2,3}.

  • Java (Android) regular expression to strip out HTML paragraph

    - by jackbot
    I have an Android application which grabs some data from an external XML source. I've stripped out some HTML from one of the XML elements, but it's in the format: <p class="x">Some text...</p> <p>Some more text</p> <p>Some final text</p> I want to extract the middle paragraph text, how can I do this? Would a regular expression be the best way? I don't really want to start including external HTML parsing libraries.

  • regular expressions: love or hate or alternatives?

    - by yamspog
    While I can see the value and usefulness of regular expressions, I also find that they are extremely complicated and difficult to create and debug. I am often at the point where I find their usefulness is offset by the difficulty in creating expressions. I am a bit astonished by the fact that there is nothing quite like them and that there hasn't been an effort to recreate them use a more verbose or less arcane syntax. so, are regular expressions here to stay? are there alternatives that are gaining traction? do other people just ignore them and write hundreds of lines of string compare functions?
