Why this code dosent work good ? I want in textBox2 to show all the links(url's) from the site www.walla.co.il
Something dosent work good with the text() function why ?
For example if im going to www.walla.co.il in internet explorer and view the source i see that the first url address there is http://www.w3.org

But in textBox2 i see the first url address as: http://www.yad1.yad2.co.il

And i want to parse all the url's from the site and show them in textBox2
In textBox1 i just show thew hole content.

This is the code:
