Thank you for the reply. I tried the link and yes, it's not working. Yet there is no such a broken link in my site.
This so called broken link contains a line that it appears on my browser's address line when I wanted to see this page in internet explorer, immediately after creating it. It belongs to the preview of this page. There is no possibility that I put this link somewhere in the document. How could I possibly obtain such an address line? I tried every other link in my document. All working well, indeed, there is no such link in my document.
I simply can not find such a link? And google too, didn't report any broken link so far.
There is something wrong in this sitemap generator. This is what I think.
