Re: [xml] Availability of libxml2-2.9.4 release candidate 2 - regexp
Thanks Daniel. I've managed to verify that the ab?c{0,1} pattern now
works. But the following pattern still appears to fail:
=>((2{1,2}|24)\.){2}2
#fails
24.24.2
Also, I see you haven't had a chance to put the test vectors in the
test/regexp dir. If you let me know what form you'd like them in I
could submit something as a patch / copy of files / whatever.
Thanks again,

Hi there,
Please can I submit the following regexp test files that should pass,
but when I test them they fail. (I'm afraid I'm not smart enough to

I've attached them and included a git patch so hopefully one of the

better. I've included them inline below so you can do a quick scan.

Re: [xml] xmllint reports non-determinist content model for schema
I think it's fair to say that Daniel isn't a great fan is XML XSD Schema, so I imagine it won't be fixed too quickly. I think libxml2's support for Relax NG is better. It might be worth seeing if you can do what you want with that.

Re: [xml] How to bind multiple IP?
If you ever do find the lines of code you need, you will obviously want to
change the following line:
addr.sin_addr.s_addr = INADDR_ANY;
to specify the particular address you want to bind to. Presumably you will
need some sort of algorithm to distribute your set of addresses to the
sockets.

Thanks.
Here is a representative sample example of binding a socket.
sd = socket(PF_INET, SOCK_DGRAM, 0);
if ( sd 0 )
{
perror(socket);
exit(1);
}
addr.sin_family = AF_INET;
addr.sin_port = htons(SERVER_PORT);
addr.sin_addr.s_addr = INADDR_ANY;
if ( bind(sd, (struct sockaddr*)addr, sizeof(addr)) 0 )

}
In libxml2, the sample code used an API, htmlreadfile(URL, ...).
I have checked a source code of that function, but I haven't found any
low level program part.
I think at least I have to know about socket that libxml2 uses
currently, then I can call bind(known_socket, ,,..)
However, i do not where it is.
Could you please tell me how to associate binding sockets with libxml2
library in the source level?
Thanks.

That sort of thing depends on your operating system. As I understand your
question, you want to simulate multiple TCP/IP clients arriving to a
server
from different IP addresses.
If you are on a *nix-style machine using the BSD sockets API, the system
call you want is bind. Normally you don't bind() a client socket, since
you want the OS to figure it out for you. But if you want to tell the OS
precisely which IP address to use, the bind call can associate the socket
with the address.

Re: [xml] Ambiguity regarding schema content and schema validation
According to VS2005 (and I agree with it) 1.xsd is not a valid schema. You can have multiple elements with the same name in the same complex type, but those elements have to have the same type. Also, I think you need to make the URIs contained in the values of your xmlns:tns and targetNamespace attributes the same (probably xmlns:tns=http://abc.com;). Even if 1.xsd were valid, I'm not sure why either 2.xml or 3.xml might pass validation as there should be a minimum requirement for two b elements.

Re: [xml] General XML Schema question
Now I would like to create a rule which says for example if the user chose the enumerator MY_SPECIAL_TYPE_STRING than the type of Value has to be xsd:string. If the enumerator was MY_SPECIAL_TYPE_INTEGER than the type of Value should be xsd:integer. And maybe if this is even possible create my own type for Value. Better places to ask this sort of question are [EMAIL PROTECTED], [EMAIL PROTECTED] and the comp.text.xml newsgroup. You may have to do a bit of detective work to find out how to subscribe to these. To answer your question, you can't use XML schema to do this. (I'm not sure even if RelaxNG can do this.) A more schema friendly way of do this would be to do: xsd:complexType xsd:choice xsd:element name=MY_SPECIAL_TYPE_STRING type=xsd:string/ xsd:element name=MY_SPECIAL_TYPE_INTEGER type=xsd:int/ xsd:element name=MY_SPECIAL_TYPE_OF_WHATEVER type=???/ /xsd:choice /xsd:complexType Your XML instance then looks like: MY_SPECIAL_TYPE_STRINGMyString/MY_SPECIAL_TYPE_STRING XSD1.1 is looking at a feature where an attribute (but not an element) can specify constraints on the type of a child element.

Re: [xml] Regexp Failure
Hi,
I think there is a residual problem related to the bug reported below. A
customer of ours is trying to match an IP address using the pattern:
((1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])\.){3}(1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])
which should match: 192.168.254.0 but doesn't.
I've tried the version of xmlregexp.c in 2.6.30 and the 2007-11-19 version
included in today's libxml2-cvs-snapshot.tar.gz snapshot.
If I manually expand the effect of the {3} as below, then the pattern
matches OK.
((1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])\.)((1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])\.)((1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])\.)(1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])
Also, if I change the pattern to: (i.e. {3} - {3,4}):
((1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])\.){3,4}(1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])
that matches OK as well.
I've tried to reduce the expression to find out where the problem is.
Interesting I've found that flipping the order around of the expressions
makes it work. i.e. when I move the 1?... part to be the last | expression
the pattern matches OK!:
((2[0-4][0-9]|25[0-5]|1?[0-9]{1,2})\.){3}(1?[0-9]{1,2}|2[0-4][0-9]|25[0-5])
I hope that gives some insight into the problem.
Thanks,

Hi,
I think the problem occurs when we have the minimum range as 0,
otherwise it works fine. I suppose the problem lies somewhere in the
generation of epsilon states when the minimum range is zero (There is
a separate bit of code for precisely that condition which I am trying
to work out at present:) ) Any pointers
Thanks!!
Yes this was related to minimum range 0, and also to a problematic
epsilon transition, but the fix required to changes parts of the graph
generation.

Re: [xml] XMLSchema status?
Original Message From: John Calcote Daniel or anyone else? Can you tell me the status of the XMLSchema library? I wonder how mature it is at this point. Can it be used to validate a document yet? In general most processors don't support 100% of schema features. If you have a particular set of schemas that you want to use in mind then the best thing might be to test that and various valid and non-valid XML instances and see what the results are. Obviously this strategy won't help if you expect the sets of schemas that you use to change rapidly. In other words, some missing features may not actually be a problem for you. (But then again, they may be!)

Re: [xml] xmlSchemaValidateDoc
Original Message From: Andreas Tscharner Original Message From: Suresh Chandak 1. Do we need to have the elements in the same order in xml as xsd ? Yes, as long as you define xs:sequence in your XSD the elements have to be in the same order in the XML as in your XSD. ... If you want to add the elements in no specific order, have a look at xs:all which you can use instead of xs:sequence in you XSD. But be careful xs:all cannot be used as a replacement of xs:sequence, there are some restrictions. The XSD book/page/reference (I use XML Schema from O'Reilly) of your choice describes it in detail... Just to add a bit more detail, the main limitation of xs:all is that minOccurs and maxOccurs are restricted to be either 0 or 1. Also, xs:any style wildcards are not allowed, nor can xs:all be or have anonymous compositors. And it can't be used in extension scenarios. Hence it might be a bit limiting for your needs. (BTW - some of these limitations maybe relaxed in XSD 1.1, but I wouldn't wait for that to come along!) I'd also recommend the book Andreas mentioned: http://www.amazon.com/XML-Schema-Eric-Van-Vlist/dp/0596002521/ Although, some reviewers seem to think it's not the best text to start with.

Re: [xml] Tool to help fill in structures from XML
Hi David,
Does anybody know of a good tool which takes the drudgery out of reading
XML into structures?
FYI - We have a tool that takes an XML Schema, and generates C++ classes
with all the marshalling and unmarshalling machinery. For more info, see:
http://www.tech-know-ware.com/lmx
However, my take of your example (below) is slightly different from your
descriptive question. If your example is closer to what you want, the Boost
library has an object serialization component. You may not get the exact
XML that you are looking for, and it might involve a little drudgery, but it
might help.
HTH,
Pete.
Specifically, what I'd like would be a tool that allows me to describe an
XML grammar (e.g. via RelaxNG) and a structure layout, and then generate
tables or code that would read an XML file and store the incoming elements
into objects in C++.
e.g. given
struct some_struct
{
int a;
int b:4;
enum {larry,moe,curly} stooge;
};
parse
some_struct a=5
b4/b
stooge which=moe/
/some_struct
and give me a filled-in some_struct object. Obviously, there would have to
be some other file which mapped the XML entities into the structure (and
vis-versa) - ideally some XML file which, when chewed upon by the proper
tool, would spit out C++ code and a RelaxNG schema.
Does anybody know of such a tool?
