I was having problems with left and right parentheses being inserted into my XML Attributes directly from the database. I found that I could solve the problem by substituting the appropriate XML entities, as follows:
LEFT PAREN <- ( RIGHT PAREN <- )
It was causing this error in my XSLT engine:
XSLT Error (javax.xml.transform.TransformerException): The reference to entity “P” must end with the ‘;’ delimiter.
fun.
Update
The above error was not caused by the parentheses, but rather by the ‘&P’ in the attribute. Changing it to ‘&P’ will fix the problem.
