Bulk sitemap generator

Need a script that can generate the links of internal pages for many sites at once. How it should work: Load into the script list of domains (from a txt file). The script generates HTML map in one file where the sites are separated by a commentary. Example: < a href=" [login to view URL]">[login to view URL] < a href=" [login to view URL]">[login to view URL] < a href=" [login to view URL]">[login to view URL] < a href=" [login to view URL]">[login to view URL]
