问题 I have a find and replace script that works no problem when the words don't have any special characters. However, there will be a lot of times where there will be special characters since it's finding names. As of now this is breaking the script.

问题 How to put a sample XML code in Javadoc? The XML code includes angle brackets which I do not want to be processed.

问题 I have CKEditor on post text where I want to insert html-code. Something like this: <pre> <code class="html"> <img src="path/to/img.jpg" /> </code> </pre> But when I save the text, CKEditor interprets img-tag as actual html-image and shows broken image.
