XML DTD not available #32

Closed AndreWaehlisch closed 6 years ago

AndreWaehlisch commented 6 years ago

I am trying to read an xmsi file with my XML library but this fails, because it cannot verify the DTD file (http://www.xmi.ugent.be/xml/xmimsim-1.0.dtd). I get a 403 Forbidden error when I try to access it in my browser.

Hi Andre,

Easiest solution is to tell the XML library not to perform DTD validation. Which library and language are you using for this?

AndreWaehlisch commented 6 years ago

I am using IDL. It seems even with validation disabled the implementation tries to download the DTD and fails. I noticed there is a local DTD in .../share/xmimsim/xmimsim-1.0.dtd. Maybe this could become the default one.

Ok thanks. IDL's XML parser indeed does not allow validation to be switched off. You could use something like this using the DTD file on the system.

nlines = FILE_LINES('test.xmsi')
sarr = STRARR(nlines)
OPENR, unit, 'test.xmsi', /GET_LUN
READF, unit, sarr
FREE_LUN, unit
str = STRJOIN(sarr, '\n')
str.replace('http://www.xmi.UGent.be/xml/','/usr/local/share/xmimsim/') ; or something similar depending on where the DTD file is on your system
xml = OBJ_NEW('IDLffXMLDOMDocument', string=str)

Disclaimer: I don't have IDL on my system anymore so I cannot test this... Second disclaimer: My IDL is rusty 😄

Yes, replacing the URL with the file name works fine now. Thank you.

You're welcome.
