XML Parsing Error: undefined entity
Line Number 255, Column 16:href="r/3t">360°
Here's a couple of options...
Option 1. Download the following entity definitions.
I concatenated the files together, but this is not necessary.
cat xhtml* >xhtml-pac.ent
Then in your xml file include a reference to the entities in your external file. You will need to describe an external entity as seen here...
<!--ENTITY spec-chars SYSTEM "resources/xhtml-pac.ent"-->This inclusion of the entity file converts special characters to unicode. The unicode will always be processed by the xml processor.
Also take a look at the Java library JTidy. The JTidy Java API provides a method in their Tidy Java class that will automatically do the above work for you. You also get cleaned xml automatically. The Java method is setNumEntities and will convert those special HTML characters into unicode.
