Allows to get current emptyness configuration for the given axlNode. An axlNode, which is a representation of a xml node, is considered to be empty only if it has no content inside it. The following xml code snipet shows what is considered the content:
<data> Xml content, data node content </data> If a node have content, this function will return false. The content must not be confused with the node childs. A xml node (axlNode) could be empty but have childs at the same time (axl_node_have_childs). The following xml code snipet shows a xml <data> node with childs that have content, but the parent node, <data> do not have content, therefore is empty.
<data> <row>Some data</row> <row>More content</row> </data> A node that is empty will return NULL data once called to axl_node_get_content.
