[libxml++] Compiling libxml++ example (myparser) in VC6.0

[tikcireviva <tik...@ya...>]

Hi Guys,

I am trying to compile the sample program "myparser" list in, but failed 
(http://libxmlplusplus.sourceforge.net/docs/manual/html/ar01s02.html#id2402334)

Here are my settings:
1. Install gtkmm-devel-2.6.2-1.exe which includes glib, glibmm, libxml 
in the same package
2. Set Include path of libxml++ for my VC6 project

However, I have the following error messages from ustring.h.
(It seems to me that in GLIBMM_HAVE_SUN_REVERSE_ITERATOR is missing out 
the support of VC6, since the "std::reverse_iterator" contains five 
parameters. Well, this is for sure not being defined under ustring.h, I 
wonder if any of you know how to fix this problem?)

c:\gtk\include\glibmm-2.4\glibmm\ustring.h(215) : error C2976: 
'reverse_iterator' : too few template arguments
        c:\program files\microsoft visual

Thank you very much for yours help, I am really appreciate that.

Best wishes,

You will have so much easier task of using libxml++ if you revert to 
version 1.04. It does not depend on GTK and it uses std::string. I'm 
using it with MSVC and Borland compiler without any problem.

I wonder if version 1.04 do support double-bytes characters or not. It 
seems to me that using glibmm is the only solution, am I right? Anyway, 
I will try version 1.04. Thank you for your suggestions.

That depends on what you mean by 'support'. libxml2 uses utf-8, and
that is easily wrapped in std::string. As long as you don't start
using the std::string API to interpret individual characters (but
rather as an opaque buffer) you will be fine.

Version 1.04 does not support unicode, but it can work fine with utf-8 
because it can be stored in std::string.
The question is do you really need utf-16 or utf-32? In 98% percent of 
cases the answer is no.

Thanks Darko, that helps either. Thank you very much.

[libxml++] Using SAX with XPath

[tikcireviva <tik...@ya...>]

Hi Everyone,

After going through a couple examples, I found that the XPath feature is 
pretty handy. And I wonder why there is XPath example for DOM instead of 
SAX? If libxml++ do support this feature, could you mind show me any 
examples or a way to tackle this?

While playing with the XPath example, I have enountered some 
difficulties in order to extract the value from "my-xpath". For 
instance, let's say if I have the following xml-like input.

    <title>A section</title>

And I have this XPath '/title', how can I get the 'A section' value from 
a node? (A node/nodeset should be in this type 'xmlpp::NodeSet' 
according to the example)
I know this is a really dumb question, and I am really hoping that you 
guys could give me a helping hand. Thank you very much.

Best wishes,

-tikcireviva.

To be able to look up nodes via xpath expressions you need a dom tree to
navigate to match the pattern from the expression. These patterns can
become arbitrarily complex and they typically involve nodes far appart
in the document (or even across multiple documents !), so matching with
a stream-based protocol would be very hard (you would have to reread the
stream over and over again).
