After the failed experiment with a static XML namespace, introduce
versions of xmlSearchNs that report malloc failures.
Optimize the no-document case by only adding the XML namespace
declaration if it wasn't found in an ancestor.
Replace xmlStringGetNodeList and xmlStringLenGetNodeList with
xmlNodeParseContentInternal which also updates an optional parent
node.
Don't look up entities a second time via xmlNewReference.
Fix many places where malloc failures aren't reported.
Make some API function return an error code. Changing the return type
from void to int is technically an ABI break but should be safe on most
platforms.
- xmlNodeSetContent
- xmlNodeSetContentLen
- xmlNodeAddContent
- xmlNodeAddContentLen
- xmlNodeSetBase
Introduce new API functions that return a separate error code if a
memory allocation fails.
- xmlNodeGetAttrValue
- xmlNodeGetBaseSafe
- xmlGetNsListSafe
Introduce private functions xmlTreeEnsureXMLDecl and xmlSplitQName4.
Don't report low-level errors to the global error handler.
Fix tree
Introduce xmlGetNsListSafe
Fix tree
Private functions were previously declared
- in header files in the root directory
- in public headers guarded with IN_LIBXML
- in libxml.h
- redundantly in source files that used them.
Consolidate all private header files in include/private.
