reading html data from a web page

[shipar]

hello, i am a new comer.

is it possible to read data (e.g. some integers followed by a unique word) from a defined web page of a defined web site?

if possible please help me or suggest me which language is appropriate to do the job.........

[jwenting]

sure. If you know how to find the data in the html of the page, there's nothing preventing you from extracting that data (except maybe knowledge of the tools you elect to use to do it).

Any programming language that can handle blocks of text will do.
Depending on the details of how you plan to find the data you may be able to use more advanced tools like regular expressions to get you to your target more quickly, but there's certainly no requirement to use them.

First he has to make up mind which language he wants to use. As same post been made in C++ forum. So I guess he has no clue, just fishing what may be easier

is this a forum only for experts? doesn't my words express that i m confused?

to jwenting:
pattern matching codes can be used. but i don't know whether browser saves a page or not (when the page is opened and i haven't saved that yet).

the exact shape of my problem is, i have opened a page in a browser then i have to read a specific data and have to send that in the parallel port for an external display.

No, not at all. You asked an incredibly general question and jwenting gave you a general answer. If you need specific answers you need to ask more specific questions.

[jwenting]

browsers generally save whatever they download somewhere, at least temporarilly.
But that's irrelevant, as any program that needs to parse html and interpret the results will have to download that html itself.
It's easier that way, and you don't introduce dependencies on system specific settings (like installed browsers, where those browsers cache things, if they cache things at all, etc. etc.).
