how to extract body contents using regexp
html, javascript, regex
Solution
Note that the string-based answers supplied above should work in most cases. The one major advantage offered by a regex solution is that you can more easily provide for a case-insensitive match on the open/close body tags. If that is not a concern to you, then there's no major reason to use regex here.
And for the people who see HTML and regex together and throw a fit...Since you are not actually trying to parse HTML with this, it is something you can do with regular expressions. If, for some reason, `content` contained `</body>` then it would fail, but aside from that, you have a sufficiently specific scenario that regular expressions are capable of doing what you want:
const strVal = yourStringValue; //obviously, this line can be omitted - just assign your string to the name strVal or put your string var in the pattern.exec call below
const pattern = /<body[^>]*>((.|[\n\r])*)<\/body>/im;
const array_matches = pattern.exec(strVal);
After the above executes, `array_matches[1]` will hold whatever came between the `<body` and `</body>` tags.
Problem
I have this code in a var. ``` <html> <head> . . anything . . </head> <body anything=""> content </body> </html> ``` or ``` <html> <head> . . anything . . </head> <body> content </body> </html> ``` result should be ``` content ```
