Re: What is a connector and what can you use it against?
Out of the box QlikView can load from http servers and from ftp servers, so for these you do not need any connector.
In addition, you can connect to ODBC and OLEDB. In principle, the ability to connect to ODBC and OLEDB is a connector supplied by QlikTech. But you could also develop a connector yourself, if you have a special database. Then QlikView will send the SELECT statement of the script to this connector instead of to ODBC.
Several of the QlikTech partners have connectors to different data sources, and QlikTech supplies one additional connector, the SAP connector.
Then you can process/filter the rows of the resulting resident table and make string operations on the tags with string functions like Replace (tags) and BetweenText etc. Or just pick out the rows you need by number if it's a fixed web site.
I made a small example which uses the HtmlTextBox Object Extension from Stefan Walther:
