  • Very simple regex not working

    - by Thomas Wanner
    I have read that to match a word inside of a string using Regular expressions (in .NET), I can use the word boundary specifier (\b) within the regex. However, none of these calls result in any matches Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\b@p1\b"); Regex.Match("INSERT INTO TEST(Col1,Col2) VALUES(@p1,@p2)", "\bINSERT\b"); Is there anything I am doing wrong ?

  • ocaml pattern match question

    - by REALFREE
    I'm trying to write a simple recursive function that look over list and return a pair of integer. This is easy to write in c/c++/java but i'm new to ocaml so somehow hard to find out the solution due to type conflict it goes like.. let rec test l = match l with [] - 0 | x::xs - if x 0 then (1+test, 0) else (0, 1+test);; I kno this is not correct one and kinda awkward.. but any help will be appreciated

  • php selecting hash using wildcards

    - by tipu
    Say I have a hashmap, $hash = array('fox' => 'some value', 'fort' => 'some value 2', 'fork' => 'some value again); I am trying to accomplish an autocomplete feature. When the user types 'fo', I would like to retrieve, via ajax, the 3 keys from $hash. When the user types 'for', I would like to only retrieve the keys fort and fork. Is this possible? What I was thinking was using binary search to isolate the keys with 'f', instead of brute-force searching. Then continue eliminating the indexes as the user types out their query. Is there a more efficient solution to this?

  • Regular expressions and the question mark

    - 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?

  • How can I extract the nth occurrence of a match in a Perl regex?

  • How can I substitute the nth occurrence of a match in a Perl regex?

    - by Zaid
    Following up from an earlier question on extracting the n'th regex match, I now need to substitute the match, if found. I thought that I could define the extraction subroutine and call it in the substitution with the /e modifier. I was obviously wrong (admittedly, I had an XY problem). use strict; use warnings; sub extract_quoted { # à la codaddict my ($string, $index) = @_; while($string =~ /'(.*?)'/g) { $index--; return $1 if(! $index); } return; } my $string = "'How can I','use' 'PERL','to process this' 'line'"; extract_quoted ( $string, 3 ); $string =~ s/&extract_quoted($string,2)/'Perl'/e; print $string; # Prints 'How can I','use' 'PERL','to process this' 'line' There are, of course, many other issues with this technique: What if there are identical matches at different positions? What if the match isn't found? In light of this situation, I'm wondering in what ways this could be implemented.

  • Iterating through String word at a time in Python

    - by AlgoMan
    I have a string buffer of a huge text file. I have to search a given words/phrases in the string buffer. Whats the efficient way to do it ? I tried using re module matches. But As i have a huge text corpus that i have to search through. This is taking large amount of time. Given a Dictionary of words and Phrases. I iterate through the each file, read that into string , search all the words and phrases in the dictionary and increment the count in the dictionary if the keys are found. One small optimization that we thought was to sort the dictionary of phrases/words with the max number of words to lowest. And then compare each word start position from the string buffer and compare the list of words. If one phrase is found, we don search for the other phrases (as it matched the longest phrase ,which is what we want) Can some one suggest how to go about word by word in the string buffer. (Iterate string buffer word by word) ? Also, Is there any other optimization that can be done on this ?

  • Apache URL rewrite query

    - by ant-1980
    Can anyone tell me how to do this? i'm stumped! I need a modified URL in this format this55-is-a-test-id-23.html But I need the 23 as a GET. I can't rely on searching for 'id' as this may occur elsewhere in the URL. Is there any way of searching for the last occurrence of id and passing that as a get using an Apache RewriteRule in .htaccess?? Many thanks Ant

  • Comparing 2 columns in the same table with the "Like" function

    - by Vic
    I'm trying to come up with a way to query the values in two different columns in the same table where the result set will indicate instances where the value of columnB doesn't contain the value of columnA. For example, my "Nodes" table contains columns "NodeName" and "DNS". The values should look similar to the following: NodeName DNS Router1 Router1.mydomain.com I want to run a query to show which rows have a DNS value that does not contain (or begin with) the value of the NodeName field. I think the query should function something similar to the following, but obviously I'm missing something with regard to the use of "Like" in this situation. SELECT NodeName, DNS WHERE DNS NOT LIKE 'NodeName%' I'm using SQL Server 2005, and any suggestions would be greatly appreciated... :)

  • Print a string that contains a certain pattern in Java

    - by jjpotter
    I am trying to find a regular expression within a line of a .csv file, so I can eventually save all the matches to another file, and lose all the other junk. So a line in my file might look like: MachineName,User,IP,VariableData,Location The VariableData is what I want to match, and if there's a match, print the line. I am using a pattern for this because I only want 3 out of 10 of variations of VariableData, and out of those 3, they are numbered differently(example, "pc104, pccrt102, pccart65"). I am trying to do this using the Scanner Class and keeping it simple as possible so I can understand it. Here is where I was heading with this...(the pattern isn't complete, just have it like this for testing). import java.io.File; import java.util.Scanner; import java.util.regex.Pattern; public class pcv { public static void main(String[] args) { File myFile = new File("c:\\temp\\report.csv"); Pattern myPat = Pattern.compile("pc"); try{ Scanner myScan = new Scanner(myFile); while(myScan.hasNext()){ if(myScan.hasNext(myPat)){ System.out.println("Test"); } } }catch(Exception e){ } } } This code loops, im guessing the .hasNext() methods are resetting themselves. I've played around with the Matcher class a little bit, but only found a way to match the expression but not get the whole line. My other throught was maybe somehow count the line that contains the pattern, then go back and print the line that corresponds to the counts.

  • PHP-REGEX: accented letters matches non-accented ones, and visceversa. How to achive it?

    - by Lightworker
    I want to do the typical higlight code. So I have something like: $valor = preg_replace("/(".$_REQUEST['txt_search'].")/iu", "<span style='background-color:yellow; font-weight:bold;'>\\1</span>", $valor); Now, the request word could be something like "josé". And with it, I want "jose" or "JOSÉ" or "José" or ... highlighted too. With this expression, if I write "josé", it matches "josé" and "JOSÉ" (and all the case variants). It always matches the accented variants only. If I search "jose", it matches "JOSE", "jose", "Jose"... but not the accented ones. So I've partially what I want, cause I have case insensitive on accented and non-accented separately. I need it fully combined, wich means accent (unicode) insensitive, so I can search "jose", and highlight "josé", "josÉ", "José", "JOSE", "JOSÉ", "JoSé", ... I don't want to do a replace of accents on the word, cause when I print it on screen I need to see the real word as it comes. Any ideas? Thanks!

  • Can anyone explain UriMatcher (Android SDK)?

    - by mobibob
    I have been tasked with designing my web services client code to use the utility class UriMatcher in the Android SDK. Unfortunately, the example in the Dev Guide does not relate to anything in my mind. I know I am missing some fundamental points to the functionality and possibly about Uri itself. If you can tie it to some web APIs that are accessible with HTTP POST request, that would be ideal.

  • C++ match string in file and get line number

    - by Corey
    I have a file with the top 1000 baby names. I want to ask the user for a name...search the file...and tell the user what rank that name is for boy names and what rank for girl names. If it isn't in boy names or girl names, it tells the user it's not among the popular names for that gender. The file is laid out like this: Rank Boy-Names Girl-Names 1 Jacob Emily 2 Michael Emma . . . Desired output for input Michael would be: Michael is 2nd most popular among boy names. If Michael is not in girl names it should say: Michael is not among the most popular girl names Though if it was, it would say: Micheal is (rank) among girl names The code I have so far is below.. I can't seem to figure it out. Thanks for any help. #include <iostream> #include <fstream> #include <string> #include <cctype> using namespace std; void find_name(string name); int main(int argc, char **argv) { string name; cout << "Please enter a baby name to search for:\n"; cin >> name; /*while(!(cin>>name)) { cout << "Please enter a baby name to search for:\n"; cin >> name; }*/ find_name(name); cin.get(); cin.get(); return 0; } void find_name(string name) { ifstream input; int line = 0; string line1 = " "; int rank; string boy_name = ""; string girl_name = ""; input.open("/<path>/babynames2004.rtf"); if (!input) { cout << "Unable to open file\n"; exit(1); } while(input.good()) { while(getline(input,line1)) { input >> rank >> boy_name >> girl_name; if (boy_name == name) { cout << name << " is ranked " << rank << " among boy names\n"; } else { cout << name << " is not among the popular boy names\n"; } if (girl_name == name) { cout << name << " is ranked " << rank << " among girl names\n"; } else { cout << name << " is not among the popular girl names\n"; } } } input.close(); }

  • READING stderr from within Awk

    - by Dave
    I want to keep SSH debug info separate (and logged) from other input. However, if I simply redirect stderr to a log file, I risk combining output from SSH and output from the remote process on the host machine (that might send something to stderr): $ ssh -v somemachine 2 file.log So, I want to filter out only those lines that match "debug1": $ ssh -v somemachine | awk '/debug1/ {print "file.log"; next} {print}' Good so far, BUT ssh's debug output goes to stderr. So... $ ssh -v somemachine 2& | awk '/debug1/ {print "file.log"; next} {print}' Foiled again! I don't want to mix stdout and stderr. BAD! What does a kid like me do? I was about to go the route of named pipes or some such wildeness, but really, all I need to know is how to get awk to match patterns from stderr ONLY.

  • 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}.

  • A maximum character limit on the preg functions?

    - by animuson
    On my site I use output buffering to grab all the output and then run it through a process function before sending it out to the browser (I don't replace anything, just break it into more manageable pieces). In this particular case, there is a massive amount of output because it is listing out a label for every country in the database (around 240 countries). The problem is that in full, my preg_match functions seems to get skipped over, it does absolutely nothing and returns no matches. However, if I remove parts of the labels (no particular part, just random pieces to reduce characters) then the preg_match functions works again. It doesn't seem to matter what I remove from the label, it just seems to be that as long as I remove so many characters. Is there some sort of cap on what the preg functions can handle or will it time out if there is too much data to be scanned over?

  • Finding partial substrings within a string

    - by Peter Chang
    I have two strings which must be compared for similarity. The algorithm must be designed to find the maximal similarity. In this instance, the ordering matters, but intervening (or missing) characters do not. Edit distance cannot be used in this case for various reasons. The situation is basically as follows: string 1: ABCDEFG string 2: AFENBCDGRDLFG the resulting algorithm would find the substrings A, BCD, FG I currently have a recursive solution, but because this must be run on massive amounts of data, any improvements would be greatly appreciated
