Captured text can be referred to in a sub() or subn() function or method by using the syntax \i or \g<id> where i is the number of the capture group and id is the name or number of the capture group so \1 is the same as \g<1>, and in this example, the same as \g<forenames> This syntax can also be used in the string passed to a match object s expand() method Why doesn t the rst part of the regex grab the entire name After all, it is using greedy matching In fact it will, but then the match will fail because although the middle names part can match zero or more times, the surname part must match exactly once, but the greedy middle names part has grabbed everything Having failed, the regular expression engine will then backtrack, giving up the last middle name and thus allowing the surname to match Although greedy matches match as much as possible, they stop if matching more would make the match fail For example, if the name is John le Carr , the regex will rst match the entire name, that is, John le Carr This satis es the rst part of the regex but leaves nothing for the surname part to match, and since the surname is mandatory (it has an implicit quanti er of 1), the regex has failed Since the middle names part is quanti ed by *, it can match zero or more times (currently it is matching twice, le and Carr ), so the regular expression engine can make it give p some of its match without causing it to fail Therefore, the regex backtracks, giving up the last \s+\w+ (ie, Carr ), so the match becomes John le Carr with the match satisfying the whole regex and with the two match groups containing the correct texts There s one weakness in the regex as written: It doesn t cope correctly with forenames that are written using an initial, such as James W Loewen , or J R R Tolkein This is because \w matches word characters and these don t include period One obvious but incorrect solution is to change the forenames part of the regex s \w+ expression to [\w]+, in both places that it occurs A period in a character class is taken to be a literal period, and character class shorthands retain their meaning inside character classes, so the new expression matches word characters or periods But this would allow for names like , , A , A , and so on In view of this, a more subtle approach is required. extract images from pdf using itextsharp in c# How to extract images from PDF files using c# and itextsharp – Tipso ...
