RegExp Writing

Hi,

this expression will :

• match any string ending with either xlsx or docx
• store the first letter in the first match group
• store xlsx or docx in the second match group

if you want the character before xlsx or docx is a dot, the expression must be :

(.)+\.(xlsx|docx)

If you want to store the name without extension, and not the first character, the expression must be :

(.+)\.(xlsx|docx)

If you don't want to store name value in match group, remove parenthesis:

.+\.(xlsx|docx)

If you don't want to store extension in match group, add ?: after the opening parenthesis

.+\.(?:xlsx|docx)
