  • fastercsv parsing to int or other into ActiveRecord

    - by Schroedinger
    I'm currently importing a CSV into an activerecord element but can't choose to parse the elements as say ints or decimals on a case by case basis using fastercsv. I can either choose to parse everything as an int or the other, or all as strings. I need to parse some columns as ints, some as decimals and some as strings. Otherwise, is there a way after I've parsed everything as strings to convert and update individual elements in the activerecord to the new form? Say parse values in as strings then convert certain values to ints, others to decs, etc?

  • How to do parsing in Objective C?

    - by Tattat
    In Java, I can easily pass data using (ObjectA)objB. How can I do the similar things in Objective C? Also, why the Objective C can't return an Object, but only can return the id only? I do -(MyObj)returnMyObject{ }, but the Xcode warning me that I can't use the MyObj, but I can return the id..... -(id) returnMyObject {}.

  • Parsing complex string using regex

    - by wojtek_z
    My regex skills are not very good and recently a new data element has thrown my parser into a loop Take the following string "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write" Previously I had the following for my regex : [+\\-/] Which would turn the result into USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read But now I have values with dashes in them which is causing bad output New string looks like "+USER=Bob Smith-GROUP=Admin+FUNCTION=Read/FUNCTION=Write/FUNCTION=Read-Write" Which gives me the following result , and breaks the key = value structure. USER=Bob Smith GROUP=Admin FUNCTION=Read FUNCTION=Write FUNCTION=Read Write Can someone help me formulate a valid regex for handling this or point me to some key / value examples. Basically I need to be able to handle + - / signs in order to get combinations.

  • simpledateformat parsing date with 'Z' literal

    - by DanInDC
    I am trying to parse a date that looks like this: 2010-04-05T17:16:00Z This is a valid date per http://www.ietf.org/rfc/rfc3339.txt. The 'Z' literal "imply that UTC is the preferred reference point for the specified time." If I try to parse it using SimpleDateFormat and this pattern: yyyy-MM-dd'T'HH:mm:ss It will be parsed as a Mon Apr 05 17:16:00 EDT 2010 SimpleDateFormat is unable to parse the string with these patterns: yyyy-MM-dd'T'HH:mm:ssz yyyy-MM-dd'T'HH:mm:ssZ I can explicitly set the TimeZone to use on the SimpleDateFormat to get the expected output, but I don't think that should be necessary. Is there something I am missing? Is there an alternative date parser?

  • Can't Prevent Nested Div's from Overflowing when using Percent Sizes and Padding in CSS?

    - by viatropos
    I want to be able to layout nested divs with these properties: width: 100% height: 100% padding: 10px I want it to be such that, the children are 100% width and height of the remaining space after padding is calculated, not before. Otherwise, when I have a document like the below example, the child makes the scrollbars appear. But the scrollbars are not the main issue, the fact that the child stretches beyond the width of the parent container is. I can use all position: absolute declarations, but that doesn't seem right. Here is the code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="X-UA-Compatible" content="IE=7"> <title>Liquid Layout</title> <style> body, html { width:100%; height:100%; margin:0; padding:0; background-color:black; } #container { position:relative; width:100%; height:100%; background-color:red; opacity:0.7; } #child1 { position:relative; width:100%; height:100%; padding:10px; background-color:blue; } #nested1 { position:relative; background-color: white; width:100%; height:100%; } </style> </head> <body> <div id="container"> <div id="child1"> <div id="nested1"></div> </div> </div> </body> </html> How do I make it so, using position:relative or position:static, and percent sizes, the percents size the children according to the parent's width/height minus padding and margins? Do I have to resort to position:absolute and left/right/top/bottom? Thanks for the help, Lance

  • Tricky file parsing. Inconsistent Delimeters

    - by Ben Truby
    I need to parse a file with the following format. 0000000 ...ISBN.. ..Author.. ..Title.. ..Edit.. ..Year.. ..Pub.. ..Comments.. NrtlExt Nrtl Next Navg NQoH UrtlExt Urtl Uext Uavg UQoH ABS NEB MBS FOL ABE0001 0-679-73378-7 ABE WOMAN IN THE DUNES (INT'L ED) 1st 64 RANDOM 0.00 13.90 0.00 10.43 0 21.00 10.50 6.44 3.22 2 2.00 0.50 2.00 2.00 ABS The ID and ISBN are not a problem, the title is. There is no set length for these fields, and there are no solid delimiters- the space can be used for most of the file. Another issue is that there is not always an entry in the comments field. When there is, there are spaced within the content. So I can get the first two, and the last fourteen. I need some help figuring out how to parse the middle six fields. This file was generated by an older program that I cannot change. I am using php to parse this file.

  • Parsing files "/etc/default" using java

    - by rmarimon
    I'm trying to parse the configuration files usually found in /etc/default using java and regular expressions. So far this is the code I have iterating over every line on each file: // remove comments from the line int hash = line.indexOf("#"); if (hash >= 0) { line = line.substring(0, hash); } // create the patterns Pattern doubleQuotePattern = Pattern.compile("\\s*([a-zA-Z_][a-zA-Z_0-9]*)\\s*=\\s*\"(.*)\"\\s*"); Pattern singleQuotePattern = Pattern.compile("\\s*([a-zA-Z_][a-zA-Z_0-9]*)\\s*=\\s*\\'(.*)\\'\\s*"); Pattern noQuotePattern = Pattern.compile("\\s*([a-zA-Z_][a-zA-Z_0-9]*)\\s*=(.*)"); // try to match each of the patterns to the line Matcher matcher = doubleQuotePattern.matcher(line); if (matcher.matches()) { System.out.println(matcher.group(1) + " == " + matcher.group(2)); } else { matcher = singleQuotePattern.matcher(line); if (matcher.matches()) { System.out.println(matcher.group(1) + " == " + matcher.group(2)); } else { matcher = noQuotePattern.matcher(line); if (matcher.matches()) { System.out.println(matcher.group(1) + " == " + matcher.group(2)); } } } This works as I expect but I'm pretty sure that I can make this way smaller by using better regular expression but I haven't had any luck. Anyone know of a better way to read these types of files?

    - by fenderplayer
    So, firstly, heres an atom feed snippet which i am trying to parse: // http://somelink.com/atom <feed xmlns="http://www.w3.org/2005/Atom"> <entry> <title>Title Here</title> <link href="http://somelink.com/link1&amp;amp;ref=rss" rel="alternate" /> <link href="http://somelink.com/link2&amp;amp;ref=rss" rel="tag:somelink.com/apply_url"/> ... </entry> i pull the atom feed like so, // In controller index method @rss = SimpleRSS.parse open('http://somelink.com/atom') Then i output the response in the view, which i am writing using haml, as follows: - @rss.entries.each do |item| .title-div = item.title .title-link = item.link //outputs the first link I could run a second loop for the links but is there a way to get the second link without it? Like reading the "rel" attribute and outputting the correct link? How do i do this in haml/rails?

  • parsing issue with comma separated csv file

    - by Andrei
    I am trying to extract 4th column from csv file (comma separated, and skipping first 2 header lines) using this command, awk 'NR <2 {next}{FS =","}{print $4}' filename.csv | more However, it doesn't work because the first column cantains comma, thus 4th column is not really 4th. Below is an example of a row: "sdfsdfsd, sfsdf", 454,fgdfg, I_want_this_column,sdfgdg

  • CSS Vertical Spacing Issue (Margin?) - Vertical Space Between Two Divs

    - by Sootah
    I've got the layout of my site mostly done. On the domain I'm testing this layout on - http://networkgenius.org/ - there is a vertical space separating the content-wrapper div and the menu div. I have the margins set to 0px for the vertical spacing, and this is the only area that is separated like it is. I'd like the white content area to be pressed up right against the bottom of the menu, so that none of the body's background shows between them. What am I doing wrong?

  • PHP robots.txt parsing

    Is there an easiest way to do this? function parse_robots_txt($URL){ $parsed = parse_url($URL); $robots = file_get_contents('http://'.$parsed['host'].'/robots.txt',FILE_TEXT); $exploded = explode('user-agent:',strtolower($robots)); foreach($exploded as $user_agent){ $user_agent = trim($user_agent); if(substr($user_agent,0,1) == '*'){ $user_agent = str_replace('#','',preg_replace('/#.*\\n/i','',$user_agent)); $user_agent = str_replace('disallow:','',substr($user_agent,1)); $user_agent = preg_replace('/allow:/i', '+-+-+-+', $user_agent, 1); $user_agent = str_replace('allow:','',$user_agent); print_r(explode('+-+-+-+',$user_agent)); } } }

  • Parsing/Tokenizing a String Containing a SQL Command

    - by Alan Storm
    Are there any open source libraries (any language, python/PHP preferred) that will tokenize/parse an ANSI SQL string into its various components? That is, if I had the following string SELECT a.foo, b.baz, a.bar FROM TABLE_A a LEFT JOIN TABLE_B b ON a.id = b.id WHERE baz = 'snafu'; I'd get back a data structure/object something like //fake PHPish $results['select-columns'] = Array[a.foo,b.baz,a.bar]; $results['tables'] = Array[TABLE_A,TABLE_B]; $results['table-aliases'] = Array[a=TABLE_A, b=TABLE_B]; //etc... Restated, I'm looking for the code in a database package that teases the SQL command apart so that the engine knows what to do with it. Searching the internet turns up a lot of results on how to parse a string WITH SQL. That's not what I want. I realize I could glop through an open source database's code to find what I want, but I was hoping for something a little more ready made, (although if you know where in the MySQL, PostgreSQL, SQLite source to look, feel free to pass it along) Thanks!

    How can I (easily) take a string such as 'sin(x)*x^2' which might be entered by a user at runtime and produce a python function that could be evaluated for any value of x? Does anyone know of any libraries or modules that takes care of this sort of thing?

  • Problem Parsing JSON Result with jQuery

    - by senfo
    I am attempting to parse JSON using jQuery and I'm running into issues. In the code below, I'm using a static file, but I've also tested using an actual URL. For some reason, the data keeps coming back as null: <!DOCTYPE html> <html> <head> <title>JSON Test</title> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> $.getJSON('results.json', function(data) { alert(data); // Result is always null }); </script> </head> <body> </body> </html> The JSON results look like the following: {"title":"HEALTHPOINT TYEE CAMPUS","link":"http://www.healthpointchc.org","id":"tag:datawarehouse.hrsa.gov,2010-04-29:/8357","org":"HEALTHPOINT TYEE CAMPUS","address":{"street-address":"4424 S. 188TH St.","locality":"Seatac","region":"Washington","postal-code":"98188-5028"},"tel":"206-444-7746","category":"Service Delivery Site","location":"47.4344818181818 -122.277672727273","update":"2010-04-28T00:00:00-05:00"} If I replace my URL with the Flickr API URL (http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?), I get back a valid JSON result that I am able to make use of. I have successfully validated my JSON at JSONLint, so I've run out of ideas as to what I might be doing wrong. Any thoughts?

  • Parsing a XML File and Replacing Chosen Node With Values From Text File

    - by transmogrify
    I wrote a C# Winforms program to take a XML file and load values from a text file into each occurrence of that field which the user specifies on the UI. For whatever reason, the program inserts a carriage return on any nodes which don't contain a value. For example, it will do that to <example></example> whereas it will not misbehave on something like <country>USA</country> What is causing it to do this and how can I prevent it? Here is the code from the part which handles this functionality. XmlDocument LoadXmlDoc = new XmlDocument(); StreamReader sr = File.OpenText(DataLoadTxtBx.Text); string InputFromTxtFile; LoadXmlDoc.Load(XmlPath.Text); XmlNodeList NodeToCreateOrReplace = LoadXmlDoc.GetElementsByTagName(XmlTagNameTxtBx.Text); foreach (XmlNode SelectedNode in NodeToCreateOrReplace) { if ((InputFromTxtFile = sr.ReadLine()) != null) { SelectedNode.InnerText = InputFromTxtFile; } } sr.Close(); LoadXmlDoc.Save(XmlPath.Text);

  • Need help parsing file/writing script

    - by Bradley Herman
    Hey all, I have been doing nothing but web development over the last few years and haven't written any Java or C++ in what feels like forever. I don't necessarily need to use these languages, so I'm entirely open to suggestion. I was given an email list by a client to import into their mailchimp account yesterday and unfortunately, Mailchimp couldn't read the file. It's a text file, but I don't believe it's tab delimited (which would make this much, much easier for me). A small portion of the file (I've changed last names and email addresses) can be viewed here: http://sparktoignite.com/patients.txt If anyone has suggestions on how I can get this into a Mailchimp readable format (csv, tab delimited txt, excel) please let me know. I feel like 3 years ago I would've been able to do this in a matter of minutes, but given that I haven't touched anything other than RoR, PHP, and jQuery for the last few years, I don't know where to start. Thanks!

  • Parsing xml with dom4j or jdom or anyhow

    - by c0mrade
    Hello, I wanna read feed entries and I'm just stuck now. Take this for example : http://stackoverflow.com/feeds/question/2084883 lets say I wanna read all the summary node value inside each entry node in document. How do I do that? I've changed many variations of code this one is closest to what I want to achieve I think : Element entryPoint = document.getRootElement(); Element elem; for(Iterator iter = entryPoint.elements().iterator(); iter.hasNext();){ elem = (Element)iter.next(); System.out.println(elem.getName()); } It goes trough all nodes in xml file and writes their name. Now what I wanted to do next is if(elem.getName() == "entry") to get only the entry nodes, how do I get elements of the entry nodes, and how to get let say summary and its value? tnx

  • Tool for parsing smtp logs that finds bounces

    - by Željko Filipin
    Our web application sends e-mails. We have lots of users, and we get lots of bounces. For example, user changes company and his company e-mail is no longer valid. To find bounces, I parse smtp log file with log parser. Some bounces are great, like 550+#[email protected]. There is [email protected] in bounce. But some do not have e-mail in error message, like 550+No+such+recipient. I have created simple ruby script that parses logs (uses log parser) to find which mail caused something like 550+No+such+recipient. I am just surprised that I could not find a tool that does it. I have found tools like zabbix and splunk for log analysis, but they look like overkill for such simple task. Anybody knows a tool that would parse smtp logs, find bounces and e-mails that cause them? Edit: smtp server is microsoft smtp server.

  • Parsing Indentation-based syntaxes in Haskell's Parsec

    - by pavpanchekha
    I'm trying to parse an indentation-based language (think Python, Haskell itself, Boo, YAML) in Haskell using Parsec. I've seen the IndentParser library, and it looks like it's the perfect match, but what I can't figure out is how to make my TokenParser into an indentation parser. Here's the code I have so far: import qualified Text.ParserCombinators.Parsec.Token as T import qualified Text.ParserCombinators.Parsec.IndentParser.Token as IT lexer = T.makeTokenParser mylangDef ident = IT.identifier lexer This throws the error: parser2.hs:29:28: Couldn't match expected type `IT.TokenParser st' against inferred type `T.GenTokenParser s u m' In the first argument of `IT.identifier', namely `lexer' In the expression: IT.identifier lexer In the definition of `ident': ident = IT.identifier lexer What am I doing wrong? How should I create an IT.TokenParser? Or is IndentParser broken and to be avoided?

  • Objective C - RegexKitLite - Parsing inner contents of a string, ie: start(.*?)end

    - by Stu
    Please consider the following: NSString *myText = @"mary had a little lamb"; NSString *regexString = @"mary(.*?)little"; for)NSString *match in [myText captureComponentsMatchedByRegex:regexString]){ NSLog(@"%@",match); } This will output to the console two things: 1) "mary had a little" 2) "had a" What I want is just the 2nd bit of information "had a". Is there is a way of matching a string and returning just the inner part? I'm fairly new to Objective C, this feels a rather trivial question yet I can't find a less messy way of doing this than incrementing an integer in the for loop and on the second iteration storing the "had a" in an NSString.
