I have a pattern as follows:
document_data/Filename.xyz
I'm trying to write a regular expression that will only return "Filename". I have one that gives me just "xyz" and it works, and I have one that gives me "Filename.xyz" but I"m having trouble chopping off the xyz to just get Filename.
[^/]+$ gives me "Filename.xyz"
\[^.]+$ gives me xyz
I'm not a regex person so any help would be great! Thanks!
try to use a lookahead (?=...):
/[^\/.]+(?=\.[^.]+$)/
A lookahead performs only a check and means followed by but match nothing.
Combine the two and wrap the first part in a capturing group:
"document_data/Filename.xyz".match(/([^/]+)\.[^.]+$/)[1]
I hope its could help (cf: http://planetozh.com/blog/2008/04/javascript-basename-and-dirname/)
function basename(path) {
return path.replace(/\\/g,'/').replace( /.*\//, '' ).replace( /\..*/, '' );
}
