I have the following string D_Doc Name L_Linked Doc Q_1_5 or D_Doc Name L_Linked

  • 0

I have the following string

D_Doc Name L_Linked Doc Q_1_5

or

D_Doc Name L_Linked Doc Q_5

I’m having a hard time creating a regex to match the following

Doc Name
Linked Doc
1_5 or 5

D_Doc Name is always present
L_ and Q_ are not

The string may also look like the following

D_Doc Name Doc Q_1_5
D_Doc Name Doc Q_5
D_Doc Name L_Linked Doc

I would like to be able to reference the matches as
match[‘DocName’] or some meaning full way so I know which match is found and which isn’t.

Any suggestions?

    If I understand you correctly, the regex you want is something like:

    ^D_(?<D>.*?)( L_(?<L>.*?))?( Q_(?<Q>.*))?$

    It produces the following results for some test inputs:

    Input                          D             L           Q 
D_Doc Name L_Linked Doc Q_1_5  Doc Name      Linked Doc  1_5
D_Doc Name Doc Q_1_5           Doc Name Doc              1_5
D_Doc Name Doc Q_5             Doc Name Doc              5
D_Doc Name L_Linked Doc        Doc Name      Linked Doc
D_Doc Name Doc Q_5             Doc Name Doc              5
