RE: Likely bug when resolving relative paths for SYSTEM identifie
rs
Hi Neil,
Appreciate you comments and I totally agree that the systemId should be a
URI. However, the parser is not consistent in enforcing it. E.g. If I've a
xml file in "C:\Test\" and have the corresponding DTD in "C:\" then the
parser succeeds with the following DOCTYPE declaration:
<!DOCTYPE foo SYSTEM "..\bar.dtd">
Further, if the DTD is not present at the expected location, in this
scenario it's "C:\", the parser throws a SAXParseException stating that the
file is not found. It's only if the you have too many of "..\" or "../", the
parser chokes. So as a user, I would expect the parser rather than to hang,
do one of the following:
1. Preferably, to enforce the condition that at all times the systemId is a
URI.
2. If it's resolving relative path's that are not URI's then should throw a
file not found error message under the above circumstances.
BTW, thanks for the backslashes tip :-)
Thanks,
Pradeep

RE: Likely bug when resolving relative paths for SYSTEM identifiersPradeep,
Use:
<!DOCTYPE foo SYSTEM "bar.dtd">
and then use an EntityResolver to return the fully qualified uri. I had
exactly the same issue. This is what was recommended to me, and it works
great.
