Manipulating XML with C#

2012-06-28T19:02:00.002+05:30

Here i am going to demonstrate how to parse through XML documents and iterate the node values and names in simple steps.

Step 1: Add the required name spaces

using System.Xml;

using System.Xml.XPath;

System.Xml contains classes related to Xml reading and writing and System.Xml.XPath namespace contains the classes that define a cursor model for navigating and editing XML information items as instances of the XQuery 1.0 and XPath 2.0 Data Model.

Step2:Create a XMLText Reader and load the XML Document

XML Text reader provides a fast , non cashed forward only access to XML data where as XML Document object can be used to load an XML formated file.

Step 3 :Create an XML Node List and iterate the values.

Upon running the code you can see that the values got populated to the array list from the xml.

RUNNING LEX AND YACC IN WINDOWS XP

To begin with, you must download the files below first(around 400KB in total). All the files should be in the same directory(flex.exe is standalone but bison.exe is not).

http://www.monmouth.com/~wstreett/lex-yacc/bison.exe

Another requirement is that you must have a c/c++ compiler(like Turbo C++ ) installed in your system. I believe everyone who has reached compiler level programming will have a c/c++ compiler installed in their system(duh!).

Now you can start your work.

1. Create a lex program and save it(like ‘x.l’ or ‘x.txt’)

2. Reach your directory through command prompt.

3. Call flex by “flex ” (eg: “flex x.l”)

4. If your lex input file doesnt have any errors, a file name “lex.yy.c” will be generated.

5. I suggest you rename “lex.yy.c” to some other more sensible name like “lex.c”, because double extensions is not a good idea in windows environment. Move the file to the folder of your compiler.

6 . Call the compiler and input lex.c to it (eg: “tcc lex.c”, where tcc is the Turbo C compiler; use any C/C++ compiler you have). If what you have is a more sophisticated environment like visual studio, you have to do the normal procedure to get a program to compile. If you use Turbo C, an object file “lex.obj’ and the executable “lex.exe” will be generated if there are no compilation problems

7. Thats it. Now just run lex.exe. Its your lexical analyser.
