libxml++-2.8.0

I've just seen that 2.9.1 is available. I will try it soon and I'll let 
you known about it.

Wich version of libxml++ are you using ?
Does the problem happen with the lastest version ?

[libxml++] Problem with setting the default namespace in create_root_node

[Ari R. <ari...@gm...>]

I sent this message yesterday morning and it hasn't gotten through
yet... I guess whoever handles moderating this list doesn't want to
wade through all the spam to find the occasional on-topic post every
day :-). Since I'm an impatient person, I decided to subscribe and
resend this.



#include <libxml++/libxml++.h>

int main()
{
  xmlpp::Document output_document;
  xmlpp::Element* output_root =
output_document.create_root_node("foo", "urn:xmlns:ExampleCode");
  return 0;
}

As far as I can see from reading the documentation, the above code
should simply create an XML document that, in serialised form, is <foo
xmlns="urn:xmlns:ExampleCode" />. Instead, it throws an exception:

terminate called after throwing an instance of 'xmlpp::exception'
  what():  The namespace () has not been declared.
Aborted

The same happens if I give "" as the third argument. If I give a
non-empty string as the namespace, create_root_node does what it
should do.

I'm not sure if I've investigated this right, but it seems to me that
what's happening is that xmlSearchNs does *not* look for the default
namespace if you pass it a pointer to a null as the third argument - it
wants a null straight instead. A fix that appears to work at least for me is
changing the xmlSearchNs line (libxml++/nodes/node.cc:195) to this:

  xmlNs* ns = xmlSearchNs( cobj()->doc, cobj(), ns_prefix == "" ? NULL
: (xmlChar*) ns_prefix.c_str());

- I successfully write the xml data into a file using=20

The frame above has __end < __beg, which is why an exception is thrown.

That seems to be because __n = std::string::npos = size_t(-1) in frame #9,
which must be passed by:

> #10 0x401c40c4 in Glib::ustring::ustring(char const*, unsigned)

>     at /usr/include/g++-v3/bits/stl_alloc.h:571

n = 169 in that frame, but Glib::ustring seems to pass -1 to the
std::string ctor. That looks as though utf8_byte_offset(src,n) returns
-1, which I think means there was an invalid UTF8 character in the
string. Is the data you pass to the string correctly UTF8-encoded?
The gdb output shows the 'é' wasn't converted from latin1 to utf-8.

[libxml++] SIGABRT received during xmlpp::Document::write_to_string_formatted

[Cyril P. <cyr...@la...>]

Hi

I'm writing an XML file with the xmlpp interface.
Everything is fine with xmlpp::Document::write_to_file_formatted();
But when I'm calling xmlpp::Document::write_to_string_formatted(), I=20
receive a SIGABRT signal.

Any idea around ?

I agree. It seems the maintainers of libxml++ are all
using at least some of the GNOME libraries anyways, so
this kind of dependency isn't an issue for them.
Just look back through the archives, where this was
discussed numerous times before.

To answer your question: ascii is a proper subset of
utf8 (which is what libxml2 uses internally), and
when you can guarantee that the xml documents you
read in don't contain anything bug ascii you will
be fine with your typedef. If not you will still be
able to technically treat the strings inside std::string,
but the usual interpretation of byte == character won't
apply any more. But that's all up to your application
code to figure out then.

		Stefan

I don't want to install glibmm and glib (glimm

I also don't want another configure process.

This problem seems like a FAQ.

Hello,
I plan to use libxml++ with the following replacement of ustring:

/glibmm/ustring.h :

}


But I don't know how "dangerous" this is.
Do I ever get problems when I only use ascii?

[libxml++] Seems like a bug in DomParser::parse_memory

[Tim A. <re...@ma...>]

Hello!

   There seems to be a UTF-8 related bug in DomParser.
   domparser.cc:71 is
     context_ = xmlCreateMemoryParserCtxt(contents.c_str(), contents.size());
   
   (as of 2.6.last and 2.8.last at least)
   shouldn't it be
     context_ = xmlCreateMemoryParserCtxt(contents.c_str(), contents.bytes());

   Otherwise my UTF-8 xml string containing some russian characters is
   told to have miscellaneous errors some bytes from end.

Thanks for you library anyway :)

[libxml++] xpath with namespaces

[Curtis S. <th...@gm...>]

Hi, 

I saw this post sometime in July, and now I am running into the same
problem.  Does anyone have an answer for this?

 Hello,
 
 I"m trying to use XPaths on documents which use namespaces (e.g. 
 libxml++-2.6.1/examples/sax_exception/example.xml). My code looks like this:
 
 xmlpp::DomParser dp;
 dp.parse_file("example.xml");
 xmlpp::Document* doc = dp.get_document();
 xmlpp::Element* root = doc->get_root_node();
 xmlpp::NodeSet set = root->find("//gjob:Jobs");
 
 If I use "//gjob:Jobs" i get "XPath error : Undefined namespace prefix", 
 and "//Jobs" just returns an empty set.
 I assume I have to register the namespace first, but I couldn"t find 
 anything about this in the documentation.
 
 thanks in advance for your help.
 
 Thomas Volpini

Thanks,

Curtis

[libxml++] WebDAV Namespace Problem

[Thomas E. <tei...@no...>]

When I get an XML Response back from a WebDAV request, DomParser throws
exceptions about the DAV: and xml: namespaces.  I can get around it by
removing the ':' before each of the above namespaces.  Is there a way to get
the Dom Parser to disregard said namespaces?
Thanks,

[libxml++] RE: AIX installation problems

My bad.  The "xlC_r: 1501-218 file

file suffix" complaints are just warnings.  The error following these is
"ld: 0711-244 ERROR: No csects or exported symbols have been saved."
I've added the "-bautoexp" binder option to get beyond that problem.
The next problem was a missing "xmlpp::KeepBlanks::Default" symbol

That command is using "cc" which is the default value make uses for CC.
Linking should probably be done with CXX, not CC, but you might be able
to force it to be right by setting CC=xlC_r (as well as CXX=xlC_r) or
setting CC to some other value.

[libxml++] AIX installation problems

[Styer, D. <dar...@lm...>]

I'm attempting to build libxml++1.0 after libxml2-2.6.9 on AIX 5.2 and
am having some problems.
I find that "configure" is unable to parse the output of "nm" and so
sets "global_symbol_pipe" to "" (null), however the shell does not like
the "pipe-space-pipe" line that is ultimately generated.  For the short
term I've changed it to ":" (colon) as a no-op.  I'm not sure what the
output is supposed to look like so haven't looked closer.  I've also
found a double semi-colon in "libxml++/nodes/node.h" the compiler
(version 6) dislikes.  My real problem is that I'm having trouble with
object files with ".lo" extensions that looks something like this

cc -Wl,-bM:SRE -o .libs/libxml++-1.0.so.1  attribute.o dtd.o document.o
noncopyable.o keepblanks.o
.libs/libxml++-1.0.lax/libparsers.al/parser.lo

-lc  ${wl}-berok -Wl,-bnoentry -Wl,-bexport:.libs/libxml++-1.0.exp

Most of the files compiled with xlC as I am setting "CXX=xlC_r", I'm not
sure why these are different.
Configure does seem to correctly set "compiler_o_lo" (Can we write
directly to a .lo ?) correctly.
Any suggestions would certainly be appreciated.

There is some examples in the source tarball of libxml++. You have the 
documentation on the website too.

You're not obliged to have a DTD for any document. However it is needed 
as soon as you want to validate your document.
So generaly, it's better to have one : validation allow you to 
concentrate on your program, not doing a lot of testing code for your input.

Re: [libxml++] Copying Document contents

[Jim G. <gar...@ca...>]

There is a function Document::create_root_node_by_import, which does
this.  However, you must merge it with the main program document first,
and then put in the other non-XML info if you do this.

Before this function existed, I had to use the C API to do stuff like
this.  I'd be interested in knowing if this function will work to solve
your problem.  Maybe a new function is needed.

[libxml++] libxml++ tutorials

[Benjamin L. <bl...@gm...>]

Hello all, I just signed up to the libxml++ mailing list and I was
wondering, where can I get libxml++ tutorials from? The libxml++ I
obtained came with my gtkmm installer, and the installer was obtained
from http://www.pcpm.ucl.ac.be/~gustin/win32_ports/binaries/gtkmm-devel-2.4.6-1.exe
which can be found at
http://www.pcpm.ucl.ac.be/~gustin/win32_ports/gtkmm.html

Thanks all
Benjamin Lau

P/s Must I have a DTD specified for my XML document? Because I can't
be bothered to write one. Too lazy :)

[libxml++] Copying Document contents

[Javier V. <jvi...@te...>]

Hi.

    Is there any way to copy a Document contents to another Document 
with the same DTD?

    I'm programing a litle app that creates a new Document in order to 
store data imported from external non XML information. After doing some 
proofing on it, I want to merge it with the main program Document.

    Thanks in advance
Javor

You also link to libxml++.so, which statically instanciate a class of 
type Document::Init (cf document.(h|cc) ). In it's constructor it 
register the callbacks.

BTW, I realised the problems we encounter with static instanciation and 
compiler other than gcc can be solver using the nifty counter idiom. I'm 
tempted to do it for next stable release, although I'll have to make 
sure it does not break ABI.

Just linking to libxml++ is enough.

Done.
I joined a little example that shows the problem (but I don't think it's 
output will help a lot to solve it).
