Subject: [xsde-users] Analyse warnings from LLVM v4 compiler
Message-ID: <A4346F51-25CF-4888-BDC0-160E3B01CD98@jmsutton.co.uk>

FYI,
	I have run Analyse from the XCode project on xsde v. 3.2.0 and it reports 5 errors in 2 files:

xmltok.c -- 1 Logic error (in unknown_toUtf8)
genx.c -- 3 Memory errors + 1 Logic error (in genxDeclareNamespace, genxDeclareElement, declareAttribute, genxAddNamespace)

(Incidently it is worth looking at the gorgeous graphical explanations of the logic for these in XCode - some are really complicated!)

I have not experienced any run-time problems with these errors

Thanks, I will take a look next time I am testing it with XCode.

Subject: [xsde-users] sequence and any element
Message-ID: <3ead2598af310c259d3605cec3d74660897@guerrillamail.com>

I am looking into xsde to see if I can use XML to configure my tiny linux box.  It requires:
1.  any defined element in schema cannot be removed but the xml file may not contain all defined element.
2.  the xml file may contain elements that are not defined in the schema.

I modified the wildcard example (email.xml, email.xds and driver.cxx) of xsde.  I try to achieve:
1.  if email.xml does not contain "from" element, will the parser skip the missing elements and validate next element?
2.  if an unknown element "abc" is found in email.xml, will the parser ignore the unknown elements?

The test code returns "expected element not encountered".  It seems the test code expects a "from" element from email.xml.  Do I break any XML rule or xsde does not support it?

Regards,
kk

XML Schema wildcards are quite limited and not really suitable for this
kind of schema extensibility. It is better to use substitution groups
with XSD/e extensions that allow you to ignore/pass-through unknown
elements. Take a look at the examples in the examples/cxx/hybrid/evolution
directory.
