Subject: [PATCH] utils: Retrieve node attributes in ovirt_resource_parse_xml()
|
|
|
2bd53e |
|
|
|
2bd53e |
This commit adds a new field to the OvirtXmlElement struct, which is
|
|
|
2bd53e |
used to retrieve an attribute from the xml node. It is optional, meaning
|
|
|
2bd53e |
that, if not informed, the function will still retrieve the node
|
|
|
2bd53e |
contents instead.
|
|
|
2bd53e |
|
|
|
2bd53e |
We also introduce ovirt_rest_xml_node_get_attr_from_path() function,
|
|
|
2bd53e |
to retrieve the given attribute value from the path below the node, much
|
|
|
2bd53e |
similar to ovirt_rest_xml_node_get_content_from_path().
