Regex to remove DOCTYPE prolog

Written by

While using HTML Tidy I needed to remove the DOCTYPE prolog to prevent
‘org.xml.sax.SAXParseException: Already seen doctype.’ exception.

Regex is quite simple, only catch is that we need to make sure we include the \n\r in our selecton and make it not greedy.

 convertedData = convertedData.replaceAll("", "");

This will consume multiline as well as single declarations

    Hi Greg,
    I am using one java library for my android project. So I am exactly getting this exception. Now its code is packaged as .jar, in which SAXParser has been used. So how can I use your above solution to handle this? Can you please give me a concrete example in Java?
    Thanks
    Regards..
