This is a lot better, but maybe its better to move this and the HTML line check below the LINE you want to check and then do

```
enum Color {
// MD-INDEX: *Defined at {{.*}}clang-tools-extra{{[\/]}}test{{[\/]}}clang-doc{{[\/]}}enum.cpp#[[@LINE-1]]*
// HTML-INDEX: <p>Defined at line [[@LINE-2]] of file {{.*}}clang-tools-extra{{[\/]}}test{{[\/]}}clang-doc{{[\/]}}enum.cpp</p>
```
Any remaining checks can go below the class, or these line checks could be MD-INDEX-LINE & HTML-INDEX-LINE, and you can list 2 prefixes to check, then only the 2 line checks would be out of order w/ the rest. WDYT?
