Subject: Omit definitions of xmlNode and xmlDocPtr if YAZ_HAVE_XML2 is unset.
X-Git-Tag: v3.0.38~26
X-Git-Url: http://git.indexdata.com/?p=yaz-moved-to-github.git;a=commitdiff_plain;h=3fa6bf34c5496f69a63469a3184251d38758c85d

Omit definitions of xmlNode and xmlDocPtr if YAZ_HAVE_XML2 is unset.

When YAZ is compiled without Libxml2 support (YAZ_HAVE_XML2 is unset),
the types xmlNode and xmlDocPtr are no longer defined in xmltypes.h.
Problem was that these dummy definitions could clash with other apps that
used Libxml2 anyway.
