https://www.w3.org/Bugs/Public/show_bug.cgi?id=29817 --- Comment #1 from Michael Kay <mike@saxonica.com> --- The example is correct. X?? does matches X occurring zero or one times, just as X? does. The difference between the two, as explained in the text below the example, as that X? matches the longest possible substring, while X?? matches the shortest possible. For example, the result of replace("AAA", "(A?)(A+)", "1=$1 2=$2") is "1=A 2=AA" while the result of replace("AAA", "(A??)(A+)", "1=$1 2=$2") is "1= 2=AAA" Michael Kay -- You are receiving this mail because: You are the QA Contact for the bug.Received on Monday, 12 September 2016 13:34:59 UTC
