Given a LL(1) grammar what is an appropriate data structure or algorithm for producing an immutable concrete syntax tree in a functionally pure manner? Please feel free to write example code in whatever language you prefer. My Idea symbol : either a token or a node result : success or failure token : a lexical token from source text...
Hello I want to make something like a meta language which gets parsed and cached to be more performant. So I need to be able to parse the meta code into objects or arrays. Startidentifier: { Endidentifier: } You can navigate through objects with a dot(.) but you can also do arithmetic/logic/relational operations. Here is an example o...
I begin with an otherwise well formed (and well working) grammar for a language. Variables, binary operators, function calls, lists, loops, conditionals, etc. To this grammar I'd like to add what I'm calling the object construct: object : object_name ARROW more_objects ; more_objects : object_name | object_name ARROW more_ob...
Dear all, I have a soap response which is RPC style, so it has 'multiref's. The response was passed to me as a String. Can I use StAX parser to parse it? Can StaX resolve mutirefs automatically? Thanks, Sarah ...
I am trying to convert a date in a particular format using strptime, and i realized that the information about AM/PM is lost. Not sure why. Here is the code. struct tm t; strptime("Wed 4/18/2007 4:28:22 PM", "%a %m/%d/%Y %H:%M:%S %p", &t); std::cout<<t.tm_hour<<endl; strptime("Wed 4/18/2007 4:28:22 AM", "%a %m/%d/%Y %H:%M:%S %p", &t); ...

0000000000033a1b subq $0x28,%rsp I am having trouble extracting 0x28 from the above line. I am able to extract subq from a big list of assembly code but i only want 0x28 since this gives me the stack size. I was thinking of using substr() function buy there are variations to it, another one could look like this: 0000000000...
i am using the HTML Agility pack to convert <font size="1">This is a test</font> to This is a test using this code: HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(html); string stripped = doc.DocumentNode.InnerText; but i ran into an issue where i have this: <font size="1">This is a test & this is a joke</font> ...
Hey there, I have got an application, that is getting data via XML-files. During the parsing-part the data is written/inserted to the local sqlite3-database on the device. So, if the data is syncronized, there does a loading-screen appear (performed in background) and is telling the user, that the data is syncronized. This is working q...
i am generating a report showing the different between fields before and after. I have it working but some of the fields are pretty long and the changes are quite subtle. I want some visualization to highlight what has changed. Similar to what you see in: Stackoverflow if you look at question edits One of the text file diff tools wh...
I have an application and need to write a program that is able to figure out attachments from all kinds of email senders (and MUAs) reliably. PHP doesn't seem to have a great MIME parser so I was hoping some other languages might. I've seen the PHP Mail Mime Parser but it's not robust at all and I know (and have confirmed) it doesn't w...
I'd like to write an idiomatic parser for a markup language like Markdown. My version will be slightly different, but I perceive at least a minor need for something like this in Clojure, and I'd like to get on it. I don't want to use a mess of RegExes (though I realize some will probably be needed), and I'd like to make something both...

I'm creating a program that parses a log file for a user's name and its GUID (Global unique identifier) using regular expressions. So far, my program extracts the data properly, and stores it in a two-column DataTable. Outputting its content with this code: foreach (DataRow dr in guids.Select("","guid")) { Console.WriteLine(...

I have a linq like syntax: MyListName.Where(Lots of stuff can() "be" in "Diff(" here).Sum(value) I am wondering whether to use a RegEx or my own parsing function?
