  • php array regular expressions

    - by bell
    I am using regular expressions in php to match postcodes found in a string. The results are being returned as an array, I was wondering if there is any way to assign variables to each of the results, something like $postcode1 = first match found $postcode2 = second match found here is my code $html = "some text here bt123ab and another postcode bt112cd"; preg_match_all("/([a-zA-Z]{2})([0-9]{2,3})([a-zA-Z]{2})/", $html, $matches, PREG_SET_ORDER); foreach ($matches as $val) { echo $val[0]; } I am very new to regular expressions and php, forgive me if this is a stupid question. Thanks in advance

  • template expressions and visual studio 2005 c++

    - by chris
    I'd like to build the olb3d library with my visual studio 2005 compiler but this failes due to template errors. To be more specific, the following expression seem to be a problem: void function(T u[Lattice::d]) On the website of the project is stated that prpably my compiler is not capable of such complicated template expressions - one should use the gcc 3.4.1. My question is now if there is a way to upgrade my vs c++ compiler so it can handle template expressions on the level as the gcc 3.4.1? Maybe it helps if I get a newer version of visual studio? Cheers C.

  • Question About Eclipse Java Debugger Conditional Breakpoints Inefficiency

    - by Personman
    I just set a conditional breakpoint in Eclipse's debugger with a mildly inefficient condition by breakpoint standards - checking whether a HashMap's value list (8 elements) contains Double.NaN. This resulted in an extremely noticeable slowdown in performance - after about five minutes, I gave up. Then I copy pasted the condition into an if statement at the exact same line, put a noop in the if, and set a normal breakpoint there. That breakpoint was reached in the expected 20-30 seconds. Is there something special that conditional breakpoints do that is different from this, or is Eclipse's implementation just kinda stupid? It seems like they could fairly easily just do exactly the same thing behind the scenes.

  • Conditional Statements - If Then vs. Select Case

    - by cloyd800
    I'm a bit new to programming, and based on the few sources I've read both on the web and the books I'm learning to teach myself they are able to define what IF THEN and SELECT CASE conditional statements are, but have failed to give a comparison as to why I would use one over the other and what best practices decide this. If I'm understanding these conditional statements correctly, then both are based on a set of conditions with an outcome based around meeting these conditions, and if no conditions are met then an alternative outcome can be defined. I'm having trouble in understanding when I would use an IF THEN statement, and when I'd use a SELECT CASE statement, and what best practices are used to define this decision. Any insight on this would be greatly appreciated!

  • Excel: conditionally format a cell using the format of another, content-matching cell

    - by Eric A. Meyer
    I have an Excel spreadsheet where I’d like to be able to create a “key” of formatted cells with unique values, and then in another sheet format cells using the key formatting. So for example, my key is as follows, with one value per cell and the visual formatting indicated in parentheses: A (red background) B (green background) C (blue background) So that’s on one sheet (or in a remote corner of the current sheet—whichever is better). Then, in an area that I mark for conditional formatting, I can type one of those three letters and have the cell where I typed it visually formatted according to the key. So if I type a “B” into one of the conditionally formatted cells, it gets a green background. (Note that I’m using backgrounds here solely for ease of explanation: ideally I want to have all visual formatting copied over, whether it’s foreground color, background color, font weight, borders, or whatever. But I’ll take what I can get, obviously.) And—just to make it extra-tricky—if I change the formatting in the key, that change should be reflected in cells that reference the key. Thus, if I change the “B” formatting in the key from a green background to a purple background, any “B” in the main sheet should switch to the new color. Similarly, it should be possible to add or remove values from the key and have those changes applied to the main data set. I’m okay with the formatting-update-on-key-change being triggered by clicking a button or something. I suspect that if any of this is possible it will require VBA, but I’ve never used it so I’ve no idea where to start if that’s the case. I’m hoping it’s possible without VBA. I know it’s possible to just use multiple conditional formats, but my use case here is that I’m trying to create the above-described capability for someone who isn’t conversant with conditional formatting. I’d like to let them be able to define a key, update it if necessary, and keep on truckin’ without me having to rewrite the spreadsheet’s formatting rules for them. --- UPDATE --- So I think I was a bit unclear about my original request. Let me try again with an image. The image shows the “key” on the left, where values and styles are defined using keyboard and mouse input. On the right, you see the data that should be formatted to match the key. Thus if I type a “C” into a cell in the Data area, it should be blue-backed. Furthermore, if I change the formatting of “C” in the Key to have a purple background, all the “C” cells should switch from blue to purple. For further craziness, if I add more to the Key (say, “D” with a yellow background) then any “D” cells will be styled to match; if I remove a Key entry, then matching values in the Data area should revert to default styling. So. Is that more clear? Is it possible, in whole or in part? I don’t have to use conditional formatting for this; in fact, at this point I suspect I probably shouldn’t. But I’m open to any approach!

  • Getting started with character and text processing (encoding, regular expressions)

    - by TK
    I'd like to learn foundations of encodings, characters and text. Understanding these is important for dealing with a large set of text whether that are log files or text source for building algorithms for collective intelligence. My current knowledge is pretty basic: something like "As long as I use UTF-8, I'm okay." I don't say I need to learn about advanced topics right away. But I need to know: Bit and bytes level knowledge of encodings. Characters and alphabets not used in English. Multi-byte encodings. (I understand some Chinese and Japanese. And parsing them is important.) Regular expressions. Algorithm for text processing. Parsing natural languages. I also need an understanding of mathematics and corpus linguistics. The current and future web (semantic, intelligent, real-time web) needs processing, parsing and analyzing large text. I'm looking for some resources (maybe books?) that get me started with some of the bullets. (I find many helpful discussion on regular expressions here on Stack Overflow. So, you don't need to suggest resources on that topic.)

  • Regex to remove conditional comments

    - by cnu
    I want a regex which can match conditional comments in a HTML source page so I can remove only those. I want to preserve the regular comments. I would also like to avoid using the .*? notation if possible. The text is foo <!--[if IE]> <style type="text/css"> ul.menu ul li{ font-size: 10px; font-weight:normal; padding-top:0px; } </style> <![endif]--> bar and I want to remove everything in <!--[if IE]> and <![endif]--> EDIT: It is because of BeautifulSoup I want to remove these tags. BeautifulSoup fails to parse and gives an incomplete source EDIT2: [if IE] isn't the only condition. There are lots more and I don't have any list of all possible combinations. EDIT3: Vinko Vrsalovic's solution works, but the actual problem why beautifulsoup failed was because of a rogue comment within the conditional comment. Like <!--[if lt IE 7.]> <script defer type="text/javascript" src="pngfix_253168.js"></script><!--png fix for IE--> <![endif]--> Notice the <!--png fix for IE--> comment? Though my problem was solve, I would love to get a regex solution for this.

  • CSS compilers and converting IE hacks to conditional css

    - by xckpd7
    Skip to bottom for question, but first, a little context. So I have been looking into CSS compilers (like Sass & Less) for a while, and have been really interested in them, not because they help me understand anything easier (I've been doing css for a couple of years now) but rather they cut down on cruft and help me see things easier. I recently have been looking into reliably implementing inline-block (and clearfix), which require lots of extraneous code & hacks. Now according to all the authorities in the field, I shouldn't put IE hacks in the same page I do my CSS in, I should make them conditional. But for me that is a really big hassle to go through and manage all this additional code, which is why I really like things like Less. Instead of applying unsemantic classes, you specify a mixin and apply it once, and you're all set. So I guess I got a little of the track (I wanted to explain my points) but bascially, I'm at the point where these CSS compilers are very useful for me, and allow me to abstract a lot of the cruft away, and reliably apply them once and then just compile it. I would like to have a way to be able to compile IE specific styles into their own conditional files (ala Less / Sass) so I don't have to deal with managing 2 files for no reason. Does anything like a script/applcation that runs and can make underscore / star hacks apart of their own file exist?

  • Java remove HTML from String without regular expressions

    - by behrk2
    Hello, I am trying to remove all HTML elements from a String. Unfortunately, I cannot use regular expressions because I am developing on the Blackberry platform and regular expressions are not yet supported. Is there any other way that I can remove HTML from a string? I read somewhere that you can use a DOM Parser, but I couldn't find much on it.

  • How to embed XBase expressions in an Xtext DSL

    - by Marcus Mathioudakis
    I am writing a simple little DSL for specifying constraints on messages, and Have been trying without success for a while to embed XBase expressions into the language. The Grammar looks like this: grammar org.xtext.businessrules.BusinessRules with org.eclipse.xtext.xbase.Xbase //import "http://www.eclipse.org/xtext/xbase/Xbase" as xbase import "http://www.eclipse.org/xtext/common/JavaVMTypes" as jvmTypes generate businessRules "http://www.xtext.org/businessrules/BusinessRules" Start: rules+=Constraint*; Constraint: {Constraint} 'FOR' 'PAYLOAD' payload=PAYLOAD 'ELEMENT' element=ID 'CONSTRAINED BY' constraint=XExpression; PAYLOAD: "SimulationSessionEvents" |"stacons" |"any" ; Range: 'above' min=INT ('below' max=INT)? |'below' max=INT ('above' min=INT)? ; When trying to parse a file such as: FOR PAYLOAD SimulationSessionEvents ELEMENT matrix CONSTRAINED BY ... I can't get it to work for ... = any kind of Arithmetic expression, although it works for ...= loop or if expression, or even just a number. As soon as I do something like '-5' or '4-5' it says Couldn't resolve reference to JvmIdentifiableElement '-', even though the Xbase.xtext Grammar looks like it allows these expressions. I don't think I'm missing any Jars, as it doesn't complain when I run the mwe workflow, but only when trying to parse the input file. Any help would be much appreciated.

  • Square Brackets in Python Regular Expressions (re.sub)

    - by user1479984
    I'm migrating wiki pages from the FlexWiki engine to the FOSwiki engine using Python regular expressions to handle the differences between the two engines' markup languages. The FlexWiki markup and the FOSwiki markup, for reference. Most of the conversion works very well, except when I try to convert the renamed links. Both wikis support renamed links in their markup. For example, Flexwiki uses: "Link To Wikipedia":[http://www.wikipedia.org/] FOSwiki uses: [[http://www.wikipedia.org/][Link To Wikipedia]] both of which produce something that looks like I'm using the regular expression renameLink = re.compile ("\"(?P<linkName>[^\"]+)\":\[(?P<linkTarget>[^\[\]]+)\]") to parse out the link elements from the FlexWiki markup, which after running through something like "Link Name":[LinkTarget] is reliably producing groups <linkName> = Link Name <linkTarget = LinkTarget My issue occurs when I try to use re.sub to insert the parsed content into the FOSwiki markup. My experience with regular expressions isn't anything to write home about, but I'm under the impression that, given the groups <linkName> = Link Name <linkTarget = LinkTarget a line like line = renameLink.sub ( "[[\g<linkTarget>][\g<linkName>]]" , line ) should produce [[LinkTarget][Link Name]] However, in the output to the text files I'm getting [[LinkTarget [[Link Name]] which breaks the renamed links. After a little bit of fiddling I managed a workaround, where line = renameLink.sub ( "[[\g<linkTarget>][ [\g<linkName>]]" , line ) produces [[LinkTarget][ [[Link Name]] which, when displayed in FOSwiki looks like <[[Link Name> <--- Which WORKS, but isn't very pretty. I've also tried line = renameLink.sub ( "[[\g<linkTarget>]" + "[\g<linkName>]]" , line ) which is producing [[linkTarget [[linkName]] There are probably thousands of instances of these renamed links in the pages I'm trying to convert, so fixing it by hand isn't any good. For the record I've run the script under Python 2.5.4 and Python 2.7.3, and gotten the same results. Am I missing something really obvious with the syntax? Or is there an easy workaround?

  • Conditional fieldgroups/fieldsets in Drupal 7

    - by seane
    Background: In Drupal 7, I have created a form with CCK (aka the Field UI). I used the Field group module to create a fieldgroup, but I need it to be conditional, meaning it will only display depending on a previous answer. Previous research: To create a conditional field, you can use hook_form_alter() to edit the #states attribute like so: function MYMODULE_form_alter(&$form, &$form_state, $form_id) { if ($form_id == 'person_info_node_form') { // Display 'field_maiden_name' only if married $form['field_maiden_name']['#states'] = array( 'visible' => array( ':input[name="field_married[und]"]' => array('value' => 'Yes'), ), ); } } However, there seems to be no way to use the States API for fieldgroups. One thing to note is that, while fields are stored in $form, fieldgroups are stored in $form['#groups'] as well as in $form['#fieldgroups']. I don't know how to distinguish between these, and with this in mind, I have tried to apply a #states attribute to a fieldgroup in the same manner as above. However, it only produces server errors. Question: Is there a way to make a fieldgroup display conditionally using the States API or some alternative approach?

  • Detecting that a MemberExpression has a value

  • Conditional hotkey or include in AutoHotKey

    - by Bowen
    Is there a way to define a Hotkey conditionally in AutoHotKey? I want to do different keyboard mappings for different machines with different physical keyboards. This is what I want to do: RegRead, ComputerName, HKEY_LOCAL_MACHINE, System\CurrentControlSet\Control\ComputerName, ComputerName If ( ComputerName = BDWELLE-DIM8300 ) { #Include %A_ScriptDir%\Mappings-BDWELLE-DIM8300.ahk } OR RegRead, ComputerName, HKEY_LOCAL_MACHINE, System\CurrentControlSet\Control\ComputerName, ComputerName If ( ComputerName = BDWELLE-DIM8300 ) { LWin::LAlt [more hotkey definitions that only apply to this machine] } but since AHK parses Hotkey definitions and #Include statements BEFORE interpreting If statements, the Hotkeys definitions (whether buried in an #Include or not) do not respect the If condition. Thanks for pointing me to AutoHotKey_L! Do you have a specific example of how to conditionally define a hotkey? The syntax is very confusing. Here's what I'm trying (after having installed AutoHotKey_L.exe in place of AutoHotKey.exe): RegRead, ComputerName, HKEY_LOCAL_MACHINE, System\CurrentControlSet\Control\ComputerName, ComputerName #If ( ComputerName = BDWELLE-DIM8300 ) LWin::LAlt but that doesn't seem to work...

  • Windows Server 2003 R2 SP2 GPO Conditional Terminal Services Client Redirection

    - by caleban
    We have a lot of mobile/home users with different client side printers attached. Most of these users don't need to print on the client side and we don't want all of these users Terminal Services sessions trying to map their client side printers and we don't want all of these drivers on the Terminal Server. What is the best way to set up around 90 users to have no client side printer redirection and 10 users to have client side printer redirection (to the printers attached to their home computers)? Do I need to create two separate OU's in AD one for redirection and one for no redirection and create two different policies one for each OU? One GPO with Client Server data redirection Do not allow client printer redirection disabled and one enabled? Is it preferrable instead to change each user's AD User Properties Enviroment Client devices Connect client printers at logon setting? Is there any for me to direct "ALL HP Printers" to a single HP Universal Printer Driver, "ALL Canon Printers" to a single Canon Universal Printer Driver, etc without specifying hundreds of unique printer names in the printsub.inf file? Thanks in advance.

  • Interpreting regular expressions using find in Linux confusion

    - by PeanutsMonkey
    I am attempting to use the find command and came across an article at http://www.linux.ie/newusers/beginners-linux-guide/find.php which states The wildcard character is escaped with a slash so BASH sends a literal asterisk to the find utility as an argument instead of performing filename expansion and passing any number of files in as arguments. for the command find . -name up\*. Being new to the world of Linux I don't quite understand how the use of a backslash which is meant to escape the meta character * is interpreted and returns results as though as it is being passed to find. Does it mean if I use the -name option I have to use a backslash to pass a wildcard and if I don't use -name I don't have to use a backslash?

  • nginx conditional Accept header

    - by manu_v
    Some mobile devices send the following incorrect requests to our servers : GET / HTTP/1.0 Accept: User-Agent : xxx The empty Accept header causes our Ruby on Rails server to throw back a 500 error. In Apache, the following directive allows us to rewrite the header before sending it to the application RoR server in order to cope with the broken devices : RequestHeader edit Accept ^$ "*/*" early We're currently setting up nginx, but achieving the same work-around is proving difficult. We are able to set : proxy_set_header Accept */*; However, this seems to have to be done inconditionally. Whenever trying to do : if ($http_accept !~ ".") { proxy_set_header Accept */*; } It complains with the message : "proxy_set_header" directive is not allowed here So, using nginx, how can we set the HTTP Accept header to */* when it is empty before sending the request to the application server ?
