xmlwrapp's Issues

Make the manual available online

It would be nice to have the manual available online, e.g. at http://vslavik.github.io/xmlwrapp/

Ideal would be to update it automatically, of course, but even if this can't be done, it would still be useful to have it, it doesn't change that often so keeping it up to date manually shouldn't be a big problem.

[Patch] add xml::node::get_namespace()

Converted from SourceForge issue 2102276, submitted by vaclavslavik

Attached patch adds xml::node::get_namespace() for accessing XML node's namespace URL.

Without it, it's not possible to access namespace information using xmlwrapp, because there's no interface to use libxml2 directly and libxml2 is namespaces aware and so hides xmlns attributes.

Add a get_line_number function

Converted from SourceForge issue 2787838, submitted by mgrundberg

Add a function that allows the user to know which line in the xml document that had a parsing error

installation fails

installing on OS X El Capitan 10.11.2

I have libxml2 and libxslt installed using homebrew and since the installations are keg-only (not symlinked), I hade to provide LDFLAGS and CPPFLAGS for ./configure to work properly. Here is the command that succeeded:

./configure LDFLAGS=-L/usr/local/opt/libxml2/lib CPPFLAGS=-I/usr/local/opt/libxml2/include

and then I ran make and the following error showed up:

Making all in include
make[1]: Nothing to be done for `all'.
Making all in src
  CXX      libxml/libxmlwrapp_la-ait_impl.lo
In file included from libxml/ait_impl.cxx:34:

      make: *** [all-recursive] Error 1

Please advise.

[Patch] Fix unittest failures

Converted from SourceForge issue 1748889, submitted by tiziano

The attached patch fixes the following unittests:

attributes 9,10
document 14

Plus it disables two xsl-subtests which fail due to changed behavior in libxslt.

Error message enhancements

Converted from SourceForge issue 2787840, submitted by mgrundberg

The line number is appended to the error message AND
If an error message is set by the user when parsing with the SAX parser, do not overwrite it with the general error message from libxml2

Build fails because cpp11.h is not included

It looks like the released xmlwrapp-0.8.0.tar.gz does not contain the cpp11.h file? Is this intentional? How am I supposed to build this?

[Patch] Fix compilation on FreeBSD

The attached patch fixes a compilation/linking error on FreeBSD.

[Patch] Remove xmlwrapp dependency on libxslt

Converted from SourceForge issue 1927398, submitted by vadz

Currently the applications using (only) libxmlwrapp (and not libxsltwrapp) still have a dependency on libxslt because of the use of xsltSaveResultTo{Filename,String} functions in xml::document.

This patch introduces an intermediate class called xslt::result which allows to move these functions calls to libxsltwrapp, thus removing this unwanted dependency. It doesn't change neither the library public API nor its behaviour.

Allow the user to set the xml namespace

Converted from SourceForge issue 2787842, submitted by mgrundberg

Added functions to allow the user to set the namespace of a node and its prefix

Fix (attr) iterators to return references to real objects, not temporary proxies

Attributes iterators, in particular, return a reference to an internal attr object owned by the iterator. This means that the reference is only valid for the lifetime of the iterator and code like this is invalid:

xml::attributes::attr& a = *(root.get_attributes().begin());
// iterator freed, including its attr object, 'a' no longer valid
a.set_namespace(xml::namespaces::ns("href2", "p2"));

This is extremely unexpected for a C++ programmer.

Fail to configure head on Debian 6, 64-bit

$ git pull
$ ./bootstrap
./bootstrap: 49: Bad substitution

"make dist" doesn't work under Ubuntu 20.04 which uses Python 3

Running bkl in dist-hook target fails under 20.04 because python is now Python 3 and we need Python 2 for it.

Unfortunately using python2 doesn't work everywhere neither (e.g. it fails under Ubuntu 18.04). Other than porting bkl to Python 3 (which is not trivial), is there any way to run it under all systems? All I can think about is to define PYTHON2 env var and use it in the makefile, which is a bit ugly but probably ought to work.

XPath support

Converted from SourceForge issue 2714356, submitted by ptomaine

It would be very useful if xmlwrapp supports XPath too. Thanks.

How can I define ns for xpath

Hello,

How can I work with namespaces xmlwrapp ? I only have default namespace in my XML document and I need to use XPATH.

Thanks,

[Patch] Parsing empty stream bug

Hello,

Is it possible to have more information about an exception?

When I catch an exception, I get the error message but not the number of the line at fault.

Thank you for your help.

_cbfo.h uses std::binary_function, which is removed in C++17.

[Patch] Build errors with 0.6.1

Converted from SourceForge issue 2816324, submitted by bennison

I got build errors with 0.6.1 running on Ubuntu 9.04. One was from the Boost Test suite and one was due to the GCC 4.3 header dependency cleanup.

I updated the tests/test.h file to remove these errors.
