decimal symbol problem (using libxml2)

Hello world,

I am having a problem with the decimal symbol. The result of writing a
floating-point-number

to an xml document (using libxml2 from xmlsoft.org) is
<number>10,1234</number>

The result I want is a dot as decimal symbol, like this
<number>10.1234</number>

If I adjust the county settings of my computer and say the decimal
symbol must be an dot it

works out fine, but this is not a very good solution because I dont
want to be dependent of

the system settings of a computer.

I have tried to use the setlocale function with setlocale(LC_ALL,
"English"). This didnt

seem to work.

Anybody has an clue?

Cheerz, David

-----------------------------
xmlTextWriterPtr writer = NULL;
xmlDocPtr doc = NULL;
char xmlFilename[100] = "uitvoer.xml";

writer = xmlNewTextWriterDoc(&doc, 0);
if (NULL != writer)
{
xmlTextWriterStartDocument(writer, NULL, "ISO-8859-1", NULL);
xmlTextWriterStartElement(writer, BAD_CAST "Main");
xmlTextWriterWriteFormatElement(writer, BAD_CAST "getal", "%f",
10.12345);
xmlTextWriterEndElement(writer);
xmlFreeTextWriter(writer);
xmlSaveFormatFile(xmlFilename, doc, 1);
xmlFreeDoc(doc);
}

hand, is, and may well do what you want since it is the standard locale.
What other locales are available is dependant on your system so you
would have to ask in a group dedicated to your implementation, possibly
a Linux group. One of my linux boxes appears to have locales en_US and
en_GB, for example, but they are not part of the C standard.

This looks like you are using the libxml2 library, which again is
non-standard and so off topic here (I use it myself, but I and all my
current customers will be set to either a British, USA or standard C
locale so I've not seen this problem). However, libxml2 has its own
mailing lists and it might be worth searching them.
http://xmlsoft.org/search.php?query=...submit=Search+...
returns a lot of hits which would be worth investigating.

Flash Gordon <spam@flash-gordon.me.ukwrites:But be careful about calling setlocale(LC_ALL, "C"). This (or the
equivalent) is done at program startup. If your program is operating
in a different locale, it must be because there was another call to
setlocale() with different arguments, possibly setlocale(LC_ALL, ""),
which "specifies the locale-specific native environment". If you set
the locale to "C", you could change the behavior of other parts of the
program that depend on a native or other locale.

It's possible to save and restore the locale; setlocale() with a null
pointer as its second argument returns a pointer to a string
representing the current locale. You can query and save the current
locale, do your stuff, then set it back.
