问题
In MS Excel I would like to use a formula to extract only the word from a cell that contains a specific character ("=") within the text.
A2: Dolly made me a homemade=cake and some muffins
A3: we had cheese=cake for dinner
A4: Everyone loves how the bakery makes some awesome=cakes
A5: Johnny made his own dinner=lastnight and then cleaned the kitchen
A6: There was a tremendous amount of raing State=Oklahoma
I would like the following from in column (A2:A4) to provide the following results in column (B2:B4).
B2: homemade=cake
B3: cheese=cake
B4: awesome=cakes
B5: dinner=lastnight
B6: State=Oklahoma
I've attempted several approaches, some closer than other, but not able to figure it out, if at all possible.
回答1:
Use an old text parsing trick that greatly increases the distance between the words with repeating zeroes through the SUBSTITUTE and REPT functions which affords a larger swipe of the intended substring.
The formula in B2 is,
=TRIM(MID(SUBSTITUTE(A2, " ", REPT(" ", 99)), MAX(1, FIND("=", SUBSTITUTE(A2, " ", REPT(" ", 99)))-50), 99))
The TRIM function (used as a wrapper) removes leading and trailing spaces.

I used 5 helper columns to do this; they could be collapsed into one very long forumula, but I prefer it this way (easier to track down source of any errors I think). Given the strings you have in A2; In B2 this finds location of "="
=SEARCH("=",A2)
In C2 this finds the instance number of the " " preceeding the "="
=B2-LEN(SUBSTITUTE(MID(A2,1,B2)," ",""))
In D2 this notes the location of that " "
=SEARCH(CHAR(33),SUBSTITUTE(A2," ",CHAR(33),C2))
In E2 this locates the " " trailing the "=", or if the "=" appears in the final word in the cell it notes the full cell length +1
=IFERROR(SEARCH(" ",A2,B2),LEN(A2)+1)
Using these values in F2 this pulls the string from the preceeding " " to the trailing " "
=MID(A2,D2+1,E2-D2-1)
