Gibt es nen Direktlink?

Reguläre Ausrücke sind immer gut! Sollte jeder halbwegs ordentliche Programmierer beherrschen.


Gibt es nen Direktlink?

Nein, man muss sich registrieren und hat dort eine Bibliothek. Dort wird dann das Buch gespeichert. Von da aus kannst du dir es als PDF oder mobile Version herunterladen.

Die Kommentare zu einem Buch über Reguläre Ausdrücke wären nicht vollständig ohne den guten alten RegEx-Witz:

Some people, when confronted with a problem, think
“I know, I'll use regular expressions.”
Now they have two problems.

Zum Experimentieren und Testen von RegEx:
Learning by Doing hilt manchmal mehr als stundenlang lesen ;-) Beides zusammen ist dann perfekt!
