[xml] about the union operator in Xquery

How is the union operator in Xquery different from traditional set operator Union?

It is much easier to compile libxml yourself. If you build and use the static library, and link this library 
to your application, then you do not need to install it on your target machine. This ensures that your 
application uses the current version of libxml and completely ignore the version installed on the target 
machine by default.

Sorry, I've never worked with HP-UX before, so any major compilation is kind of a mistery to me.

I made the code based on the API posted on your libxml2 site, to create a xmlDocPtr I used xmlReadDoc and 
xmlReadFile to create the pointer from a file or from a char* (Because this functions allowed me to set na 
option to ignore whitespaces). As this functions don't exist in HP-UX and I've never worked with HP-UX (a 
collegue of mine does the instalation) I was hopping that you or someone with more know how that me of the 
libxml2 could get me some way to create a xmlDocPtr without any ignorable whitespaces with the functions that 
are implemented in HP-UX.


Sorry about my lack of experience in libxml2 and if you could get me na alternative to the function I would 
be very thankful

  I really don't know that there is an official HP-UX libxml2 version, I don't remember being contacted about 
this.


there must me a way to do this without using the

  Since I do not understand what "do this" mean, I really can't see how I could give any hint.

Well, if you are compiling your source code with a C compiler, download 
the newer source code version of the xml library and compile it on 
HP-UX.  Seems like a no-brainer to me... you can even install the 
library in a private area that only your executable knows about if you 
are worried about breaking compatability with other apps that are using 
the library.  This is what I did on .. gasp.. SCO Unix.

Hi There,

I'm in a jam right now, first I used the xmlWriter API and it didn't

How can I create a xmlDocPtr with no whitespaces, using the functions 
availble in HP-UX?

Please help, I've got until today to deliver this !?!?!?

But that's what I'm saying... you don't need to install it "on the 
system".  Just install it in the working directory where you are 
compling your application.  Then link your application against (even 
statically if you have to...) the library.

Maybe I'm missing something...

  This was said already. THERE IS NO HP-UX RELEASE FROM THE PROJECT. Simply grab the sources of the latest 
release and recompile.

  Well, if you don't listen to what we say, it will take forever until you get the information.

workable for everyone (well most people).


A MTA responsible for this mailing list is likely responsible for other 
gnome.org mailing lists. I doubt that this list is treated in any 
special way. The setup of that MTA, or it's use of virus scanners, is 
better discussed elsewhere. That not because it is off-topic, it does 
concern us all, but because all gnome.org lists are equally involved. 
That other place, that "elsewhere", is where administrators of those 
mail servers can hear you. There will be more information there.

Just don't ask me where that place is. ;-)


Some of these questions perhaps should not even be considered in the
open email forum.  However, a smaller group may be able to address the 
problems and help Daniel Veillard out.


The best way to help Daniel is to take care of yourself. If he knows 
that his subscribers have secured themselves, then he doesn't need to 
worry about being blamed for someone's grief.

Everyone must realise that mailing lists are not a secure medium. The 
subscription system fights spam successfully, but has little chance 
against self-spreading worms. Because it was never designed for a battle 
against its own subscribers.

The excellent Bruce Schneier's "Applied Cryptography" was for 
professionals with high security demands at the time it was written. 
Today it seems our ten year old kids must study its security aspects 
before they can play with the home computer without suffering damage 
from the faceless.

Simply put, protect yourself. Build your walls, but never believe you 
are safe. Rather assume that your walls will fall sooner or later and 
take care to detect the breach and minimise the damage. With that, not 
to mention your own benefit, you will give Daniel and every other list 
maintainer more help than they ever hoped for.

That being said, I would gladly address the problems and discuss about 
the ways to make the list traffic more secure. I have some ideas, even 
if they are a bit radical. But I do think this duscussion should not be 
held on this mailing list.

But... if you didn't compile libxml2 and installed it on the machine you 
are working on, which library are you using? HP doesn't deliver libxml2 
preinstalled on their PA-RISC systems. Someone must have installed it at 
some point, perhaps as a part of something else, GNOME perhaps?

With that, it can well be that you are trying to use the old libxml 
version 1.x.x which somehow ended up on the system. That won't work. Can 
you do a xmllint --version, what does it say?

There is nothing specific to HP-UX in libxml2. It has the same functions 
on all platforms. Follow the advices given to you so far. Install the 
recent version in your home directory, no privileges needed for that, 
and link your program using the static libxml2.a.

Hmm... by the way... if you don't make your schedule, does it leave a 
free place for an external at Infineon? :-) :-)  Hm... shouldn't have

Hi Daniel,

 First of all, thank you for all the support, I know I've been quite a = drag.

 I already tried before to use xmlKeepBlanksDefault(0) but with no = efective results but I don't use 
xmlParseMemory, I use xmlParseFile and = xmlParseDoc, is the effect any diferent, I though that they all 
would have the same behavior.


[Code]

        xmlDocPtr doc;
        doc =3D xmlParseFile(xmlFileName);
        xmlKeepBlanksDefault(0);

[/Code]

Thanks again for the support,

You don't seem to listen. :-) You were advised to compile and install it 
yourself, using your home directory where you certainly have write 
access. You don't run HP-UX from a CD-ROM. Your machine can have 
managers galore, you can always install things in your home directory. 
In fact, there is nothing your manager can do to prevent it... hm, 
unless he told you that there will be a free place for an external 
should you try to install something :-)

And what for dependencies? Libxml depends on nothing but the C runtime. 
Iconv and zlib you can configure away.


Daniel Veillard already gave me some clues, I will follow them to see

Yes, it's a good idea to follow Daniel's advice on libxml.
