After clicking "scrape similar" you must keep in mind a new popup home window with a tiny spread sheet within it.

For the most un-tailored scrapes that this scraper can accomplish, that's all there is to it. You can click the "copy to clipboard" button as well as proceed in a spread sheet with your recently scuffed details.

The message we originally selected was inside of a table, which in html is built using elements (or table information), every "box" in the table is bordered by html tags, therefore a preliminary XPath query of "// td" would certainly return the values in each of packages of the table. You can try this out by just modifying the "selector" box to hold "// td.".
In our first scrape, however, note that we only received values for the initial column in the table, along with the the URLs of those nation entrances.

The additional component in the question ("/ a") refers to the HTML component for a support, or a web link. In HTML this component looks like Web link Text. Somehow this scraper is wise. Or at the very least opinionated, in that it made a decision to immediately query the aspect which contains all that we can possible want from ideal clicking on an entrance that is a bolded link in the very first column.
