Using conditions
Let us assume that this table corresponds to table[5] inside the HTML page.
Sometimes, we do not know ahead of time where exactly the information is located. Take the example of the IBM stock.
You can write the following extraction rule: html->table[5].tr[i].td[2].txt where html->table[5].tr[i].td[0].txt = “IBM”
Conditions involve index ranges only.
Conditions are resolved against node properties, not nodes themselves.
