However I ca't understand what this code could do wrong. I also tried 0
instead of XML_PATTERN_XPATH, no success.

I would be relly grateful if someone has an enlightening idea.

  Late, but hopefully still useful !

  Patterns works only on a subset of XPath, they are minimalist but
allow to stream and filter without building a full tree in memory.
Instead of trying to express namespaces in the XPath expression
use them at pattern compilation time, something like:

const char *ns[4] = {"";, "i18n",
                     NULL, NULL};
pattern= "//*[ i18n:*]"

p = xmlPatterncompile(pattern, NULL, XML_PATTERN_XPATH, &ns);

this should work and be less convoluted
