Good text book on extracting data from HTML(Web)

[VX_Xc]

I need to extract messy data from the website. Could anyone recommend a good textbook that covers how to extract data efficiently from the web, plz?

Thank you.

Seunghoon,

Do you mean automatically or as in copy/paste?  If it is the latter, I'll be doing an SGF presentation on the topic in April, titled 'Copy and Paste Almost Anything'.  I already presented a draft of the paper at one of my local user group meetings and you can find it at:

I meant automatically. For example I would like to learn PROC (with many optional statements) that extracts data from the HTML file if I give it a address of a website or .html file directory.

maybe there isn't one? Then I would have to use DATA steps with a lot of @<tag> arguments in INPUT statement, which would not be very practical.

But thanks for the link. I will have a look, looks promising.

Then you want to look into proc html and proc soap.  Do a search on the discussion forums for either.  If you include my id or friedeggs id in the search, I'm sure that will help to eliminate much of the noise.

Yes. You can do it.

filename x url 'http://www.sas.com';
data want(where=(line is not missing));
infile x dsd dlm='<>' lrecl=32767;
input @ '>' line : $400. @@;
run;
