I'm spending my second hour on scripting, and just realized that it's impossible to understand inside the script that some text is exists. If and Do/While operators does their job only for current cursor position. The result is nice scripting like this:

```
# Primary Cover - backasswards because FindInLine 
# does exception if nothing found
FindInLine "<artists>"
MoveChar -18
If "</images>"
    # We sure now that primary image exists
    OutputTo "COVERURL"
    GotoChar 1
    FindInLine "type=\"primary\" uri=\""
    SayUntil "\""
EndIf

```

Luckily tag in this particular case always exists. If less lucky, the puzzle could be unresolvable.

It would be great to have something like, for example, IfExists operator:

```
# Primary Cover
IfExists "<image type=\"primary\""
    OutputTo "COVERURL"
    GotoChar 1
    FindInLine "<image type=\"primary\" uri=\""
    SayUntil "\""
EndIfExists
```
