  • Convert Javascript Regular Expression to PHP (PCRE) Expression

    - by Matt
    Hi all, I am up to my neck in regular expressions, and I have this regular expression that works in javascript (and flash) that I just can't get working in PHP Here it is: var number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; var oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]' + '|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; var str = '(?:\"' + oneChar + '*\")'; var varName = '\\$(?:' + oneChar + '[^ ,]*)'; var func = '(?:{[ ]*' + oneChar + '[^ ]*)'; // Will match a value in a well-formed JSON file. // If the input is not well-formed, may match strangely, but not in an unsafe // way. // Since this only matches value tokens, it does not match whitespace, colons, // or commas. var jsonToken = new RegExp( '(?:false|true|null' +'|[\\}]' + '|' + varName + '|' + func + '|' + number + '|' + str + ')', 'g'); If you want it fully assembled here it is: /(?:false|true|null|[\}]|\$(?:(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ,]*)|(?:{[ ]*(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))[^ ]*)|(?:-?\b(?:0|[1-9][0-9]*)(?:\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\b)|(?:"(?:[^\0-\x08\x0a-\x1f"\\]|\\(?:["/\\bfnrt]|u[0-9A-Fa-f]{4}))*"))/g Interestingly enough, its very similar to JSON. I need this regular expression to work in PHP... Here's what I have in PHP: $number = '(?:-?\\b(?:0|[1-9][0-9]*)(?:\\.[0-9]+)?(?:[eE][+-]?[0-9]+)?\\b)'; $oneChar = '(?:[^\\0-\\x08\\x0a-\\x1f\"\\\\]|\\\\(?:[\"/\\\\bfnrt]|u[0-9A-Fa-f]{4}))'; $string = '(?:\"'.$oneChar.'*\")'; $varName = '\\$(?:'.$oneChar.'[^ ,]*)'; $func = '(?:{[ ]*'.$oneChar.'[^ ]*)'; $jsonToken = '(?:false|true|null' .'|[\\}]' .'|'.$varName .'|'.$func .'|'.$number .'|'.$string .')'; echo $jsonToken; preg_match_all($jsonToken, $content, $out); return $out; Here's what happens if I try using preg_match_all(): Warning: preg_match_all() [function.preg-match-all]: Compilation failed: nothing to repeat at offset 0 in /Users/Matt/Sites/Templating/json/Jeeves.php on line 88 Any help would be much appreciated! Thanks, Matt

  • d:DesignData issue, Visual Studio 2010 cant build after adding sample design data with Expression Bl

    - by Valko
    Hi, VS 2010 solution and Silverlight project builds fine, then: I open MyView.xaml view in Expression Blend 4 Add sample data from class (I use my class defined in the same project) after I add new sample design data with Expression blend 4, everything looks fine, you see the added sample data in the EB 4 fine, you also see the data in VS 2010 designer too. Close the EB 4, and next VS 2010 build is giving me this errors: Error 7 XAML Namespace http://schemas.microsoft.com/expression/blend/2008 is not resolved. C:\Code\source\...myview.xaml and: Error 12 Object reference not set to an instance of an object. ... TestSampleData.xaml when I open the TestSampleData.xaml I see that namespace for my class used to define sample data is not recognized. However this namespace and the class itself exist in the same project! If I remove the design data from the MyView.xaml: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" it builds fine and the namespace in TestSampleData.xaml is recognized this time?? and then if add: d:DataContext="{d:DesignData /SampleData/TestSampleData.xaml}" I again see in the VS 2010 designer sample data, but the next build fails and again I see studio cant find the namespace in my TestSampleData.xaml containing sample data. That cycle is driving me crazy. Am I missing something here, is it not possible to have your class defining sample design data in the same project you have the MyView.xaml view?? cheers Valko

  • Dynamic expression tree how to

    - by Savvas Sopiadis
    Hello everybody! Implemented a generic repository with several Methods. One of those is this: public IEnumerable<T> Find(Expression<Func<T, bool>> where) { return _objectSet.Where(where); } Given to be it is easy to call this like this: Expression<Func<Culture, bool>> whereClause = c => c.CultureId > 4 ; return cultureRepository.Find(whereClause).AsQueryable(); But now i see (realize) that this kind of quering is "limiting only to one criteria". What i would like to do is this: in the above example c is of type Culture. Culture has several properties like CultureId, Name, Displayname,... How would i express the following: CultureId 4 and Name.contains('de') and in another execution Name.contains('us') and Displayname.contains('ca') and .... Those queries should be created dynamically. I had a look in Expression trees (as i thought this to be a solution to my problem - btw i never used them before) but i cannot find anything which points to my requirement. How can this be costructed? Thanks in advance

  • Matching math expression with regular expression?

    - by Ethan
    For example, these are valid math expressions: a * b + c -a * (b / 1.50) (apple + (-0.5)) * (boy - 1) And these are invalid math expressions: --a *+ b @ 1.5.0 // two consecutive signs, two consecutive operators, invalid operator, invalid number -a * b + 1) // unmatched parentheses a) * (b + c) / (d // unmatched parentheses I have no problem with matching float numbers, but have difficulty with parentheses matching. Any idea? If there is better solution than regular expression, I'll accept as well. But regex is preferred.

  • Boolean Expression Evaluation in Java

    - by Trilok
    Hey everyone, Is there a relatively simpler (when compared with writing a parser) way to evaluate boolean expressions in Java? I do not want to use the JEP library. I have a String expression something like: (x 4 || x < 8 && p 6) [ I will replace the variables with values. Is there a way by which I can evaluate this expression? The problem is, this can be any level deep. So, writing a parser would be really complex. Thanks

  • Expression Encoder SDK - WMA Pro Codec Issues with Windows Server 2003

    - by PortageMonkey
    I am using the Expression Encoder SDK to encode .avi and Flash files to a .wmv format suitable for Silverlight. By default, EE encodes files with audio using the the WMA PRO codec. If you are running Windows Server 2003, this is a problem as it doesn't support the WMA PRO codec and produces and error message similar to the following. Error Message: The Audio Profile settings do not match a valid system profile. Error Source: Microsoft.Expression.Encoder Error Target Site: System.String GetProfileString() I am looking for a way to change the default audio codec to something suitable for WS 2003. I am aware that although not supported natively, there is a highly invasive way to install Windows Media Player 11 and it's codecs on WS 2003 but this involves registry tinkering and other hacks not suitable for our production environments so that solution is out.

  • Storing expression references to data base

    - by Marcus
    I have standard arithmetic expressions sotred as strings eg. "WIDTH * 2 + HEIGHT * 2" In this example WIDTH and HEIGHT references other objects in my system and the literals WIDTH and HEIGHT refers to a property (Name) on those objects. The problem I'm having is when the Name property on an expression object changes the expression won't match anymore. One solution I came up with is to instead of storing "WIDTH * 2 + HEIGHT * 2" i store "{ID_OF_WIDTH} * 2 + {ID_OF_HEIGHT} * 2" And let my parser be able to parse this new syntax and implement an interface or such on referenced objects IExpressionReference { string IdentifierName { get; } } Anyone have a better/alternative solution to my problem?

  • Storing expression template functors

    - by UncaughtException
    Hello guys, at the moment I'm really interested in expression templates and want to code a library for writing and differentiating mathematical functions with a lambda-style syntax. At the moment, I'm able to write (_x * _x)(2); and get the correct result 4. But I would really like to do something like MathFunction f = _x * _x; f(2);, but I don't have any ideas on how to cope with the recursive expression templates on the right side. Is it possible to achieve this without using the 'auto'-Keyword instead of MathFunction or having to make the operator() virtual? Thanks for your help!

  • Express XPath as an expression tree

    - by 47d_
    If I have an XPath query like NodeA/NodeB[@WIDTH and not(@WIDTH="20")] | NodeC[@WIDTH and not(@WIDTH="20")]/NodeD Is there any API available to visualize this XPath query as a stack of atomic expressions, something like (following is generic) Get results of NodeA, call it "first set" Get results of NodeB from "first set" Filter where [@WIDTH and not(@WIDTH="20")] Filter NodeD, call this "node d for B" Get results of NodeC from "first set" Filter where [@WIDTH and not(@WIDTH="20")] Filter NodeD, call this "node d for C" Combine "node d for B" and "node d for C" I am trying to see if we can convert the XPath expression into custom expression which is close to english and vice versa. If no API is available, what would be the best approach? Thanks in advance.

  • Enumerable.Range in and Expression and Entity Framework

    - by eka808
    I'm currently developping an expression method (used in linq to entity queries) who has to give me a daycount for a given period (start date and end date) decrementing this daycount if specials days are in the period. My idea was the following : Generate an enumerable with all the dates (and with Enumerable.Range) Make a .Where on this enumerable to remove the specials dates Like a MyEnumerable.Where(a = a != "20120101") After that, return a MyEnumerable.Count() I come with this code : return (p) => Enumerable .Range(1, 4) .Where(a => a != 20120101) .AsQueryable() .Count() I tried to cast as a list, as a queryable, both (like the example) and no way ! it doesn't work ! I always get this error : LINQ to Entities does not recognize the method 'System.Collections.Generic.IEnumerable`1[System.Int32] Range(Int32, Int32)' method, and this method cannot be translated into a store expression. Have you got an idea about that ? Using an enumerable is of course not mandatory, any working solutions is good ^^ Thank's by advance !

  • C# Regular Expression for Regular Expression Parsing

    - by Chris
    I want to returns matches from a regular expression string. The regex string is: (?<TICKER>[A-Z]+)(?<SPACE>\\s)(?<MONTH_ALPHA_ABBREV>Jan|Feb|Mar|Apr|May|Jun|Jul|Sep|Oct|Nov|Dec)(?<SPACE>\\s)(?<DAY>\\d+)(?<SPACE>\\s)(?<YEAR_LONG>[2][0][0-9][0-9])(?<SPACE>\\s)(?<STRIKE_DOLLAR>\\d+(?=[.]))[.](?<STRIKE_DECIMAL>(?<=[.])\\d+)(?<SPACE>\\s)(?<PUTCALL_LONG>Call|Put) And I want to get matches for all of the group names and all of the items within square brackets (including the square brackets) outside of open and closed parenthesis. I have this regex: ((?<=[<])([A-Z]|[_])+(?=[>]))|(\\[.\\]) But this returns square bracket items within the parenthesis. To be more specific these are the matches I want from the regex at the top (keep in mind this needs to be flexible for any regex): TICKER SPACE MONTH_ALPHA_ABBREV SPACE DAY SPACE YEAR_LONG SPACE STRIKE_DOLLAR [.] STRIKE_DECIMAL SPACE PUTCALL_LONG

  • Mixing regular expression and other conditional expression in a bash if statement

    - by Tassos
    I can't get around this for quite sometime now. As I read along manuals and tutorials I'm getting more confused. I want an if statement with the following logic: if [ -n $drupal_version ] && [[ "$drupal_version" =~ DRUPAL-[6-9]-[1-9][1-9] ]]; then but I can't get it to work properly. When the script is evaluated using the "bash -x ... " script construct, works ok but when is run as a regular script my expression is not evaluated (eventhough the above condition should be met the else part is run). Could you provide any help?

  • How to use Common Table Expression and check no duplication in SQL Server

    - by vodkhang
    I have a table references to itself. User table: id, username, managerid and managerid links back to id Now, I want to get all the managers including direct manager, manager of direct manager, so on and so forth... The problem is that I do not want to have a unstop recursive sql. So, I want to check if an id alreay in a list, I will not include it anymore. Here is my sql for that: with all_managers (id, username, managerid, idlist) as ( select u1.id, u1.username, u1.managerid, ' ' from users u1, users u2 where u1.id = u2.managerid and u2.id = 6 UNION ALL select u.id, u.username, u.managerid, idlist + ' ' + u.id from all_managers a, users u where a.managerid = u.id and charindex(cast(u.id as nvarchar(5)), idlist) != 0 ) select id, username from all_managers; The problem is that in this line: select u1.id, u1.username, u1.managerid, ' ' The SQL Server complains with me that I can not put ' ' as the initialized for idlist. nvarchar(40) does not work as well. I do not know how to declare it inside a common table expression like this one. Usually, in db2, I can just put varchar(40) My sample data: ID UserName ManagerID 1 admin 1 2 a 1 3 b 1 4 c 2 What I want to do is that I want to find all managers of c guy. The result should be: admin, a, b. Some of the user can be his manager (like admin) because the ManagerID does not allow NULL and some does not have direct manager. With common table expression, it can lead to an infinite recursive. So, I am also trying to avoid that situation by trying to not include the id twice. For example, in the 1st iteration, we already have id : 1, so, in the 2nd iteration and later on, 1 should never be allowed. I also want to ask if my current approach is good or not and any other solutions? Because if I have a big database with a deep hierarchy, I will have to initialize a big varchar to keep it and it consumes memory, right?

  • Built-in precedence in Expression Trees for math?

    - by jdk
    I'm unable to find the .NET FCL built-in concept of precedence to leverage while constructing Expression Trees. Ref System.Linq.Expressions Namespace. Is this something that must be handled manually in code, or is it somehow implicit and I'm not recognizing it (e.g. maybe through helper methods or classes)? I want to apply it to math operations to ensure 3 + 5 * 10 results in 53 instead of 80.

  • regular expression

    - by Jeeenda
    Hi I need a regular expression that'll give me something like this part ./something\", [something.sh from something like this string ("./something\", [something.sh", ["./something\", [something.sh"], [/* 37 vars */]) is that possible? I'm having real trouble making this since there's that \" escape sequence and also that ',' character, so I cannot simply use match everything instead of these characters. I'm working on unix so it's also possible to use pipeline of few greps or something like that. Thanks for advice.
