It’s very easy to get and analyze voters list using my new XT_HTTP package
We can get up-voters list by the URL:
where NNNN is Idea ID from nomenee’s page.
I don’t like to import certificates, so i cannot use httpuritype for HTTPS pages and I decided to create package which will work with https as http.
It was pretty easy with java stored procedures github/XT_HTTP
java source: xt_http.jsp
create or replace and compile java source named xt_http as
In Part 1 I demonstrated how to "scrape" data from the live webpages with the votes of the Oracle Database Developer Choice Awards. Unfortunately those webpages are not ideal for scraping, so I promised a workaround. Here I do a semi-manual scraping af data by using a browser to retrieve the actual HTML, save it to a file, and then let the code parse out the data from the file.
You know about the Oracle Database Developer Choice Awards voting, right? If not, then go vote now, please, and then come back and read on :-) I want to be able to query the voting status, who is ranked what in each category and so on. But I don't want to type in votes in a table, especially not when they change all the time. Instead I'd like to query the live data in the HTML webpages. Can that be done? Yes it can...
Often, the biggest problem with regular expressions is that those who use them sometimes don’t use them correctly. A great example occurs in the Oracle Database with the REGEXP_LIKE function. For example, some developer use the following to validate whether a string is a number but it only validates whether the first character is a number.
Indexes are separate data structures that provide alternate pathways to finding data. They can and do generally speed up the processing of queries and other DML commands, like the INSERT, UPDATE, REPLACE INTO, and DELETE statements. Indexes are also called fast access paths.
