How can i do sitemap for only one catalog? example ,I want make sitemap only in "addforum-html" in my site,and are not the whole site's sitemap? which software should be selected ?how to use?
you need to go for paid version and in paid version there is such facility that you can create sitemap for perticular section.
I think you can configure most sitemap generator programs to only include certains directories in a website scan / sitemap output. You can also try my sitemap creator program. Just set root path the directory you want and start scanning. If you need more complicated setups, that is easy to configure as well.
Try this one: Free Online Sitemap Generator, and just input the url in the box. I think this can make a sitemap just one for catalog of page.
