Looks like the xml is not good, i test it with a xml validator:

I decided to try making a programming language again after my last unsuccessful attempt, so now I figured how to write a good AST and it works great when the nodes are hard-coded into a test program. But to make a language out of it, I need a parser to build the tree according to an input file. I ran into a problem here:
YACC input file:
Code:
%{
#include "nodes/allnodes.h"
#include "Node.h"
int vars[26];
%}
%token SEMICOLON INTEGER VARIABLE IF WHILE DO OPAREN CPAREN OBRACE CBRACE
%right ASSIGN
%left NE
%left PLUS MINUS
%left TIMES DIVIDE
%% .....
As you might see, each nonterminal creates a Node* object and uses it as its value. The problem is that the literal tokens, however, don't return Node*'s and I don't know what to do. I would like to be able to convert literal tokens to nodes in the Lex file (which would avoid the problem), but the problem is with the assignment operator, which takes a Node* for the right-hand side and a variable name (not a Variable Node, because they just evaluate the the variable's value and you can't change the variable with them) for the left hand side.
I wrote a C++ program that uses two different parsers. The first parser is reading program arguments from command line:./mybin arg1 arg2 ...then during program execution there's an interactive prompt asking for more parameters:
...
>> (second bunch of arguments here)
...
I'd like to run my program inside a bash script, but I don't know how to give the second level arguments.
I'm woring on a personal research project and would like to know if there are lilypond parsers for python available or I'll have to create my own. Just in case you are wondering: I don't need to typeset the content of the lilypond file, just understand what's written in the file (what notes, what duration, when in time to play each one, etc).

Probably a stupid sounding question, but bear with me please. I need to use the link grammar parser in order to do some part of speech tagging. It's freely available and works once you run the makefile or 'make' it or however it's correctly said. Thing is, it has a C API which I intend to use. And once I ran a bit of the sample code given in the documentation it gave a whole host of errors. This is very confusing because I'm including the path for the folder that has all the header files.
gcc -I/path/include/ filename.c. But it still gives me errors about not being able to find things that are clearly defined there. An hour of trudging around the internet tells me I need to 'compile' the API first. I'm not exactly sure how or if I'm supposed to do that. If someone could just shed light on this it would be greatly appreciated. I grow increasingly cynical to the musical swell of my tiny brain rattling in my skull.
I'm trying to develop an html template parser employing Flex & Bison, but now I found a problem and I don't know if surrender, so let's see if you can guide me to the solution (if any).
[Code]...
(Here I simplified the code to make only print what it gets, but it returns a token and the text to the bison program). Now my problem is that I would like to get the unknown characters as an unique string. [using the flex file above, returns char by char all HTML code that is not a comment!].
So, Could it be possible to make a flex rule that gets the HTML code?. It is not necessary to check if HTML code is correct I do it (before parse) using expat. Also there is no need to check the resulted code it will be done by the parser or compiler of the used language.
I know that are a lot of tools that uses this kind of templates in all languages and systems... but I'm just exercising my pour flex&bison skills. Also, using my current flex file, I have to remove the string "<!--MARKUP" from the beginning and "-->" from the end of returned string to bison... But in reality, if I could manage the HTML code as a flex rule, I could solve that sednding to bison an start Token, the code and and end token.
I have logs files from freeradius that have looks as follows:
$ grep "Login incorrect (rlm_ldap: User not found" /var/log/radius/radiusd-inner-tunnel-20090831.log
Mon Aug 31 09:25:27 2009 : Auth: Login incorrect (rlm_ldap: User not found): [John Doe] (from client oficina port 0 via TLS tunnel)
[code]....
I use the following line to get the amount of users that don't exist on ldap:
Code:
grep "Login incorrect (rlm_ldap: User not found" /var/log/radius/radiusd-inner-tunnel-20090831.log | awk '{print $14}' | sort -fu | wc -l
Now, awk on line one for example parses [John Doe] and [Joon Williams] as "[John" and that it's not what I'd want. I mean how could I do for awk looks username field as closed between squared brackets?
The first is about implementing function calls. The way I currently have it is that functions are called with a C++ std::vector of nodes as the parameters. How would I turn a comma-seperated list of expressions into a C++ vector in the grammar?Second, how do you implement left-associative operators in a parser that does not allow left recursion?
And third, what would be the best internal representation of integers? A C++ int seems simplest, but limited. Using GMP seems more versatile, but I'm afraid it might seriously slow down the interpreter compared to C++ ints.
Is there a Linux system call that can be used to get the group name from the GID returned by stat()? I realize that I could parse /etc/groups (if my user had sufficient permissions).

There are lots of values in format like "3m1.057s" are stored in variable_test separated with an space between two such values. For exapmple, value is "3m1.057s" I need to save different parts of a value in three separate array variables such as the
var_hour=3
var_min=1
var_sec= 057
tell if this can be done using "awk". A "WHILE" loop might be used to separate and store theses values I guess?

As a curious side project I'm playing with mzXML data(an xml format for holding mass spec data). A typical scan can be quite large, even up into GB size. I'm wondering how would one go about parsing an xml file in sections, one section at a time. The idea being if the computer doesn't have enough memory to load up the entire data file, work on chunks of it at a time.

Groovy is an object-oriented programming language for the Java platform. I do not have experience in Java, only perl and shell scripts. Recently I have been asked to maintain a software written in groovy (also to make enhancements). So can I learn groovy without knowing java language. or isit I have to learn java before venturing into groovy.
