• Regular expression help parsing SQLIO output

  - by jaspernygaard

  Hi I've been working on a regular expression to parse the output of a series of SQLIO runs. I've gotten pretty far, but not quite there yet. I'm seeking a 100% regex solution and no pre-manipulation of the input. Could anyone assist with a little guidance with the following regular expression: .*v(?<SQLIOVersion>\d\.\d).*\n.*\n(?<threads>\d*)\s.*for\s(?<Seconds>\d+).*\n.*using\s(?<clustersize>[0-9]*)KB.*\n.*\n.*size:\s(?<currentfilesize>\d+).*\n.*\n.*\n.*\n.*\s(?<IOs>\d*\.\d*).*\n.*\s(?<MBs>\d*\.\d*).*\n.*\n.*\s(?<MinLatency_ms>\d+).*\n.*\s(?<AvgLatency_ms>\d+).*\n.*\s(?<MaxLatency_ms>\d+).*\n.*\n.*\n\%\:..(?<ms>\d*\s+)* Here's a snippet of the output - note the headers, which change during the SQLIO batch run: File

• Possible Google Analytics Bug - Traffic Sources Total Visits not matching Total Visits in other repo

  - by SBAStats

  Hello, Has anyone else seen this issue? As of roughly 2 weeks ago, I get conflicting figures for the Total Visits metric between the Traffic Sources report and the other reports (e.g. Visitors, Dashboard). For example, for the week of 5/9/2010 through 5/15/2010, the Dashboard and Visitors reports both say 386 Visits. The Traffic Sources report says 157 Visits, and the 4 main source types (Search, Direct, Referral, Other) sum to 157 Visits, not 386. Any ideas? Is this a known bug, or could there be a configuration issue? Thanks.

• Xcode iphone sdk - Searching in UITableView, different pattern matching

  - by Lorenzo

  Hi everyone, I'm coding a UITableView with a UISearchBar to search between a list of cities (loaded in the uitableview) Here is my code for searhing: - (void) searchTableView { NSString *searchText = searchBar.text; NSMutableArray *searchArray = [[NSMutableArray alloc] init]; for (NSDictionary *dictionary in listOfItems) { NSArray *array = [dictionary objectForKey:@"Cities"]; [searchArray addObjectsFromArray:array]; } for (NSString *sTemp in searchArray) { NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) [copyListOfItems addObject:sTemp]; } [searchArray release]; searchArray = nil;} And with this everything works fine, but i need to do something a bit different. I need to search only between items that match pattern Word* and not * Word *. For example if I search "roma", this need to match just with "Roma" or "Romania" and not with "Castelli di Roma". Is that possible with this searchbar? How can i modify this? Thanks

• preg_match basics question.

  - by Yo-L

  Hi all. Got some trouble with my preg_match. The code. $text = 'tel: 012 213 123. mobil: 0303 11234'; $regex_string = '/(tel|Tel|TEL)[\s|:]+(.+)[\.|\n]/'; preg_match($regex_string , $text, $match); And I get this result in $match[2] "012 213 123. mobil: 023 123 123" First question. I want the regex to stop at the .(dot) but it doesent. Can someone explain to why it isnt? Second question. preg_match uses () to get their match. Is it possible to skip the parentheses surrounding the different "Tel" and still get the same functionality? Thnx all stackoverflow is great :D

• HTML, CSS: overbar matching square root symbol

  - by Pindatjuh

  Is there a way in HTML and/or CSS to do the following, but then correctly: √¯¯¯¯¯¯φ·(2π−γ) Such that there is an overbar above the expression, which neatly aligns with the &radic;? I know there is the Unicode &macr;, that looks like the overbar I need (as used in the above example, though as you can see – it doesn't align well with the root symbol). The solution I'm looking for works at least for one standard font, on most sizes, and all modern browsers. I can't use images; I'd like to have a pure HTML4/CSS way, without client scripting. Here is my current code, thank you Matthew Jones (+1) for the text-decoration: overline! Still some problems <div style="font-family: Georgia; font-size: 200%"> <span style="vertical-align: -15%;">&radic;</span><span style="text-decoration: overline;">&nbsp;x&nbsp;+&nbsp;1&nbsp;</span> </div> The line doesn't match the &radic; because I lowered it with 15% baseline height. (Because the default placement is not nice) The line thickness doesn't match the thickness of the &radic;. Thanks!

• How to exclude rows where matching join is in an SQL tree

  - by Greg K

  Sorry for the poor title, I couldn't think how to concisely describe this problem. I have a set of items that should have a 1-to-1 relationship with an attribute. I have a query to return those rows where the data is wrong and this relationship has been broken (1-to-many). I'm gathering these rows to fix them and restore this 1-to-1 relationship. This is a theoretical simplification of my actual problem but I'll post example table schema here as it was requested. item table: +------------+------------+-----------+ | item_id | name | attr_id | +------------+------------+-----------+ | 1 | BMW 320d | 20 | | 1 | BMW 320d | 21 | | 2 | BMW 335i | 23 | | 2 | BMW 335i | 34 | +------------+------------+-----------+ attribute table: +---------+-----------------+------------+ | attr_id | value | parent_id | +---------+-----------------+------------+ | 20 | SE | 21 | | 21 | M Sport | 0 | | 23 | AC | 24 | | 24 | Climate control | 0 | .... | 34 | Leather seats | 0 | +---------+-----------------+------------+ A simple query to return items with more than one attribute. SELECT item_id, COUNT(DISTINCT(attr_id)) AS attributes FROM item GROUP BY item_id HAVING attributes > 1 This gets me a result set like so: +-----------+------------+ | item_id | attributes | +-----------+------------+ | 1 | 2 | | 2 | 2 | | 3 | 2 | -- etc. -- However, there's an exception. The attribute table can hold a tree structure, via parent links in the table. For certain rows, parent_id can hold the ID of another attribute. There's only one level to this tree. Example: +---------+-----------------+------------+ | attr_id | value | parent_id | +---------+-----------------+------------+ | 20 | SE | 21 | | 21 | M Sport | 0 | .... I do not want to retrieve items in my original query where, for a pair of associated attributes, they related like attributes 20 & 21. I do want to retrieve items where: the attributes have no parent for two or more attributes they are not related (e.g. attributes 23 & 34) Example result desired, just the item ID: +------------+ | item_id | +------------+ | 2 | +------------+ How can I join against attributes from items and exclude these rows? Do I use a temporary table or can I achieve this from a single query? Thanks.

• Hashbytes comparison in stored proceduring not matching record

  - by Michael Itzoe

  The password field in my user table (SQL Server 2008) is encrypted using HASHBYTES on insertion. I have a stored procedure with parameters for the username and plain-text password which does a SELECT using that username and the password sent through HASHBYTES, then returns the user record if it finds a match. The SP is always returning an empty recordset, but if I copy and paste just the SELECT from the SP to a new query window, it returns the matched record. There're no other statements in the SP. I'm missing something here; what is it?

• The best way to deploy one site for two companies in ColdFusion?

  - by Ofeargall

  My client has multiple companies; different names/logos etc, but all the content on the sites are identical with the exception of said names/logos. In a ColdFusion environment, what would be the best way for me to serve up identical content and swap out the logos/company names on the fly so I can keep everything in one spot? Is this a jQuery solution? regex? Or will ColdFusion enable me to deploy this in an efficient manner based on the url and session variables?

• find whether the string starts and ends with the same word

  - by Ajax

  I am trying to check whether the string starts and ends with the same word. egearth. s=raw_input(); m=re.search(r"^(earth).*(earth)$",s) if m is not None: print "found" my problem is when the string consists only of one word eg: earth At present I have hard coded this case by if m is not None or s=='earth': print "found" Is there any other way to do this? EDIT: words in a string are separated by spaces. looking for a regex solution some examples: "earth is earth" ,"earth", -- valid "earthearth", "eartheeearth", "earth earth mars" -- invalid

• One regular expression to match parts in various positions

  - by richsage

  Hi all, I'm trying to parse a DSN (from a Symfony application) using regular expressions, in order to link with a secondary application, but using the same database. The DSN I currently have is: mysql:dbname=my_db_name;host=localhost with a regex of: /^(\w+):(dbname=(\w+))?;?(host=(\w+))?/ (using preg_match()). This matches OK, but fails in my test environment because the DSN elements are switched around, thus: mysql:host=localhost;dbname=my_testdb_name I could just switch them round, yes :-) but I'm sure that extraction of the host and dbname parts from both DSNs is possible with a single regular expression, and I'd like to be able to enhance my knowledge at the same time ;-) Is there a way I can do this?

• Spaces around all hyphens in a string without double-up

  - by Dave

  I'm after a regex that puts spaces around each "-" in a string, eg. 02 jaguar-leopard, tiger-panther 08 would become 02 jaguar - leopard, tiger - panther 08 Note that if the "-" already has spaces around it, no changes are to be made, eg. 02 jaguar - leopard, tiger - panther 08 should not become 02 jaguar - leopard, tiger - panther 08 The number of hyphens are unknown in advance. Thanks for any ideas... Edit: I'm not actually using a language for this. I'm using Ant Renamer (a mass file renaming utility). There are two fields in the renamer GUI, "Expression" and "New name" to provide inputs. This is from the help file as an example: Swapping artist and title from mp3 file names: "Expression" = (.*) - (.*)\.mp3 "New name" = $2 - $1.mp3 Extract episode number and title from series video files with episode number as SnnEmm followed by title: "Expression" = Code\.Quantum\.S([0-9]{2})E([0-9]{2})\.(.*)\.FRENCH.XViD\.avi "New name" = Code Quantum - $1$2 - $3.avi

• MySQL move data from one table to another, matching ID's

  - by Reveller

  I have (a.o.) two MySQL tables with (a.o.) the following columns: tweets: ------------------------------------- id text from_user_id from_user ------------------------------------- 1 Cool tweet! 13295354 tradeny 2 Tweeeeeeeet 43232544 bolleke 3 Yet another 13295354 tradeny 4 Something.. 53546443 janusz4 users: ------------------------------------- id from_user num_tweets from_user_id ------------------------------------- 1 tradeny 2235 2 bolleke 432 3 janusz4 5354 I now want to normalize the tweets table, replacing tweets.from_user with an integer that matches users.id. Secondly, I want to fill in the corresponding users.from_user_id, Finally, I want to delete tweets.from_user_id so that the end result would look like: tweets: ------------------------ id text from_user ------------------------ 1 Cool tweet! 1 2 Tweeeeeeeet 2 3 Yet another 1 4 Something.. 3 users: ------------------------------------- id from_user num_tweets from_user_id ------------------------------------- 1 tradeny 2235 13295354 2 bolleke 432 43232544 3 janusz4 5354 53546443 My question is whether one could help me form the proper queries for this. I have only come so far: UPDATE tweets SET from_user = (SELECT id FROM users WHERE from_user = tweets.from_user) WHERE... UPDATE users SET from_user_id = (SELECT from_user_id FROM tweets WHERE from_user = tweets.from_user) WHERE... ALTER TABLE tweets DROP from_user_id Any help would be greatly appreciated :-)

• Exclude records matching subquery

  - by Skudd

  There is probably an obvious answer to this question, but I am having one heck of a time getting anywhere with it. Consider the query: SELECT * FROM reports AS r JOIN reportvalues AS rv ON rv.report_id = r.report_id JOIN metrics AS m ON m.metric_id = rv.metric_id WHERE r.report_id NOT IN( SELECT DISTINCT report_id FROM exclude_report ) In this query, exclude_report is a view constructed in a similar manner. Now what happens is the query takes an EXTREMELY long time to execute, presumably because the subquery is being executed over each and every row in the parent query. However, I am finding no feasible means of doing this any other way. Oh great SQL wizards, please advise. I really need a way of doing this all in SQL, which I will be using in SSRS.

• c# finding matching words in table column using Linq2Sql

  - by David Liddle

  I am trying to use Linq2Sql to return all rows that contain values from a list of strings. The linq2sql class object has a string property that contains words separated by spaces. public class MyObject { public string MyProperty { get; set; } } Example MyProperty values are: MyObject1.MyProperty = "text1 text2 text3 text4" MyObject2.MyProperty = "text2" For example, using a string collection, I pass the below list var list = new List<>() { "text2", "text4" } This would return both items in my example above as they both contain "text2" value. I attempted the following using the below code however, because of my extension method the Linq2Sql cannot be evaluated. public static IQueryable<MyObject> WithProperty(this IQueryable<MyProperty> qry, IList<string> p) { return from t in qry where t.MyProperty.Contains(p, ' ') select t; } I also wrote an extension method public static bool Contains(this string str, IList<string> list, char seperator) { if (String.IsNullOrEmpty(str) || list == null) return false; var splitStr = str.Split(new char[] { seperator }, StringSplitOptions.RemoveEmptyEntries); foreach (string s in splitStr) foreach (string l in list) if (String.Compare(s, l, true) == 0) return true; return false; } Any help or ideas on how I could achieve this?

• Weird behavior of matching array keys after json_decode()

  - by arnorhs

  I've got some very weird behavior in my PHP code. I don't know if this is actually a good SO question, since it almost looks like a bug in PHP. I had this problem in a project of mine and isolated the problem: // json object that will be converted into an array $json = '{"5":"88"}'; $jsonvar = (array) json_decode($json); // notice: Casting to an array // Displaying the array: var_dump($jsonvar); // Testing if the key is there var_dump(isset($jsonvar["5"])); var_dump(isset($jsonvar[5])); That code outputs the following: array(1) { ["5"]=> string(2) "88" } bool(false) bool(false) The big problem: Both of those tests should produce bool(true) - if you create the same array using regular php arrays, this is what you'll see: // Let's create a similar PHP array in a regular manner: $phparr = array("5" => "88"); // Displaying the array: var_dump($phparr); // Testing if the key is there var_dump(isset($phparr["5"])); var_dump(isset($phparr[5])); The output of that: array(1) { [5]=> string(2) "88" } bool(true) bool(true) So this doesn't really make sense. I've tested this on two different installations of PHP/apache. You can copy-paste the code to a php file yourself to test it. It must have something to do with the casting from an object to an array.

• How to extract img src, title and alt from html using php?

  - by Sam

  I would like to create a page where all images which reside on my website are listed with title and alternative representation. I already wrote me a little program to find and load all html files, but now I am stuck at how to extract src, title and alt from the html < img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny"/ I guess this should be done with some regex, but since the order of the tags may vary, and I need all of them, I don't really know how to parse this in an elegant way (I could do it the hard char by char way, but thats painful).

• XamlXmlReader.Read() does not yield matching XamlNodeType.StartObject and XamlNodeType.EndObject on

  - by Yuval

  Hi, I am trying to parse a valid xaml file using the XamlXmlReader. It looks like it is 'skipping' some elements when when Read() is called. for example on the following xaml snippet: <UserControl.Resources> <Converters:AnyDbTypeToDisplayNameConverter x:Key="anyDbTypeToDisplayNameConverter" /> </UserControl.Resources> when reading I first get a XamlNodeType.StartObject on UserControl.Resources - makes sense then another XamlNodeType.StartObject on Converters - also cool. but then i do not get a XamlNodeType.EndObject on the Converters and immediately jump to the next line and does not report a XamlNodeType.StartObject. Any Idea if this is working as design ? looks like a bug to me

• Searching for simple variable names like 'c' or 'x' in Emacs.

  - by wpeters

  I often wish to search for variables that are simply called 'c' or 'count'. For example int c, count; Unfortunately when I use an incremental search for 'c' or 'count' I get a lot of unnecessary hits like the 'c' in 'choice', or the 'count' in 'wordcount' which do not interest me. I know Emacs can do i-searches with regular expressions but I don't know the correct regular expression needed to match just 'c' and 'count'. These words are often surrounded by any number of white spaces. Anyone know the regex I can use to narrow my search?

  Working in ASP.NET (VB), I am trying to develop a simple search results page for my website. The process is as follows: (1) The site's user enters a search phrase; (2) The search results page searched the site's database, and returns the page title as a link, and a short snippet from each search "hit", with the search phrase highlighted. I already have the search part done, and also the "highlighted" part done (using Regex). However, I want to be able to return a short snippet of text, which include the search phrase (a few words before the search phrase, a few after). Something like: Page Title [as a link] ... yada yada yada search phrase yada yada yada...

• Regular Expression - Password Validation is not working

  - by Kesavan

  Hi, I have to validate the password using regex. The password rule is like at least 1 uppercase and at least 2 numeric. It works fine except if the character comes at the end of the string. The regular expression which i am using is "^(?=.*\d.{2})(?=.*[A-Z].{1})(?=.*[@#$%^&+=].{2}).{8,12}$" Rules: minimum length = 8 minimum uppercase = 1 minimum numeric = 2 minimum special character = 1 It works for Test123$$, Test$123, TEST123$s, Test123$1, Test12$3 but it fails if the character specified comes at the end of the string like Test123$, Test$a12, Test12aa@, 123aa@@T. Please let me know if there is any fix for this.

• Java - Unknown characters passing as [a-zA-z0-9]*?

  - by Twodordan

  Hello, I'm no expert in regex but I need to parse some input I have no control over, and make sure I filter away any strings that don't have A-z and/or 0-9. When I run this, Pattern p = Pattern.compile("^[a-zA-Z0-9]*$"); //fixed typo if(!p.matcher(gottenData).matches()) System.out.println(someData); //someData contains gottenData certain spaces + an unknown symbol somehow slip through the filter (gottenData is the red rectangle): In case you're wondering, it DOES also display Text, it's not all like that. For now, I don't mind the [?] as long as it also contains some string along with it. Please help. [EDIT] as far as I can tell from the (very large) input, the [?]'s are either white spaces either nothing at all; maybe there's some sort of encoding issue, also perhaps something to do with #text nodes (input is xml)
