consider the following HTML code:
<html>
<head>
<title>Example website</title>
</head>
<body>
<div>
<table id='tableid'>
<tr>
<td>
<a href="/blabla" title="Blabla1">Blabla1</a>
<a href="/blabla" title="Blabla1">Blabla2</a>
<a href="/blabla" title="Blabla1">Blabla3</a>
<a href="/blabla" title="Blabla1">Blabla4</a>
</td>
<td>col2</td>
<td>col3</td>
<td>col4</td>
</tr>
</table>
</body>
</html>
If I want to get all the links why do I have to use:
//table[@id="tableid"]//a/@href
instead if using a single / after the table? I'm alredy on the table node at that point (it should become my 'root') so / should be enough...
thanks in advance!

A single / after table[@id="tableid"] would work if you only wanted immediate children of table. To get any descendent a of table[@id="tableid"], you need //a.
// is short for /descendant-or-self::node()/
The descendant-or-self axis contains the context node and the descendants of the context node. Since you're establishing the context node as table[@id="tableid"], you won't get any a elements other than those that are descendants of table[@id="tableid"].
