Web Clipping

I don't have a sample, but I do have a couple of suggestions. Do the tables you want have a class name?

If so, you can still use <directinvoke> in a mashup and then filter the result by the class name value. If necessary, you can use a separate <directinvoke> for each table.

If there really isn't any way to simply filter out the content, then consider using the Dapper Connector. You would need to set up an account for Dapper. Then use the connector to define a service and publish it in Presto. Dapper allows you to select content directly from a view of the page, so you should be able to select just the tables you are interested in.

If you do not have class names for the tables, I think you can iterate to the table(s) you want by addressing the array entry.

<assign fromexpr="$result//xhtml:table[1]"  outputvariable="myfirsttable" />

<assign fromexpr="$result//xhtml:table[8]"  outputvariable="mysecondtable" />

Following is a mashup which clips tracking information from FedEx web site.

It is a little dated, so might not work if FedEx changed format of their page. Hopefully they have not. In any case should give you a starting point.

Alexi's sample looks like it is showing a similar thing.

  <time>{$transit//xhtml:td[3]/string()}</time> 

You address the cell ( in this case the table column you want, but like my example said, show the table you want )
