Changes in this release:- Ensure stripped HTML tags replaced with a ! to prevent ISBN running into another number making it invalid
I found a situation where the decision to strip all html tags in 1.3 caused some ISBNs not being detected. It is because the raw html had a <br/> tag shielding the ISBN number from the next line, which if it coincidentally happened to start with a number meant that the two numbers got merged together. As the combined length was not valid for an ISBN the number would get thrown away. This release fixes that problem.
