I have an idea for a hobby project which performs some code analysis and manipulation. This project will require both the concrete and abstract syntax trees of a given source file. Additionally, bi-directional references between the two trees would be helpful. I would like to avoid the work of transcribing a grammar to construct my own l...
I'm using jquery DynaCloud with wordCount to create a dynamic tagcloud. I have specific terms to include in the cloud (though the frequency is different for each user), and some of the terms are multiple word, or have special characters ("&", "'", " ", etc.) as part of the term. I break the terms with specific html blocks: <pre><span...

I have a C# WPF application that is suddenly throwing an exception on startup, and I cannot figure out why. The exception is a C++ HRException, and it occurs in MSCORLIB in CreateInstanceSlow(), which is called from CreateInstance(), which is called from BamlRecordReader.CreateInstanceFromType() in the System.Windows.Markup assembly. I m...

I use anchors in my URLs, allowing people to bookmark 'active pages' in a web application. I used anchors because they fit easily within the GWT history mechanism. My existing implementation encodes navigation and data information into the anchor, separated by the '-' character. I.e. creating anchors like #location-location-key-value-k...
I have a simple XML with a CDATA section like: <?xml version="1.0" encoding="ISO-8859-1" ?> <config> <input> <![CDATA[ line another line and another ]]> </input> ... </config> And I have the current code for parsing the CDATA section using MSXML. for (int i = 0, count = pChildNodes->Getlength(); i < count; ++i) { ...
On JSON.org the essential data structures that JSON represents are given as A collection of name/value pairs, and An ordered list of values. I have not been able to find anywhere whether a second member having the same name as one already parsed into the current object should (a) throw an exception or (b) replace the existing membe...
I'm trying to build a bbcode parser, but I'm having quite some problems figuring out how to avoid matching too widely. For example I want to implement a [list] to conversion like this: \[list\](.*)\[/list\] would be replaced by this: <ul>$1</ul> This works fine, except if I have two lists where the regular expression matches the b...
Are there any best practices that I should follow while writing a parser? ...
I'm trying to write a string processing function in F#, which looks like this: let rec Process html = match html with | '-' :: '-' :: '>' :: tail -> ("→" |> List.of_seq) @ Process tail | head :: tail -> head :: Process tail | [] -> [] My pattern matching expression against several elements is a bit ugly (the whole '-' :: ...
What's the best algorithm for evaluating a mathematical expression? I'd like to be able to optimize this a little in the sense that I may have one formula with various variables, which I may need to evaluate hundreds of times using different variables. So basically if I can initially parse the formula so that it is optimized in some way,...
Lets say you have a class SomeClass which has its own implementation of toString(), and also has the ability to parse a new instance of itself by reading that same string. Which of these methods do you prefer, or find better to use? You can either define it as another constructor: public SomeClass(String serializedString); or you can...
Hey all, I have a string ($string for this example) and I want to do the following: Parse the string and convert all links within it to "actual links" (adding the open/close anchor tag) -- what is the best way to do this? I tried using preg_split() to create an array of the links contained in the string, with the idea of using str_repl...

In this i would like to separate the blocks in SQL code. for example, in the code below for condition1 loop stmt1; for condition2 loop stmt2; end loop; end loop; i want to separate these two blocks and create a data structure which will contain outer loop block and will also have inner loop bloc...
I have a list of function calls stored in a database, and for some function calls, I care about what the arguments of the function call are. I am parsing C source code with my program (which is in C#). I'm trying to find the best way of getting the function calls with the arguments. I read the source code into a string prior to parsin...
My application reads an Excel file using VSTO and adds read data to a StringDictionary. It adds only data that is a number with few digits (1000 1000,2 1000,34 - comma is a delimiter in Russian standards). What is better to check current string being appropriate number? object data, string key; // data had read try { Convert.ToDoubl...
