DOS批处理 & 脚本技术（批处理室） » [Help] Extracting matching strings under Windows

Under Windows, how can text-processing tools output matching strings? For example, if I want to output all .com domain names from a webpage's source code. How should this be written with sed, grep, awk (are there any other programs?), etc.? Many thanks. If I want to match .cn, .net, and other domain names, how should I use “OR” logic?

grep.exe -o "\.com" should probably meet the requirement like this, but I don't know whether writing it this way is accurate. How should the other command-line ones be written? I found a problem, for example: grep.exe -o "aa\.com can only match aakkjkk.com and cannot match aaaaaaaakkjkk.com. Why does grep regex match from the back?
