Understanding the advanced capabilities of ConfD is not always clear. For instance, how to navigate through the hierarchical structures of an XML document requires the use of XPath notations to navigate properly. Since XML serves as the encoding format for NETCONF and a data model defined in YANG is represented in XML, it was natural for NETCONF and YANG to utilize XPath.
XPath as a tool is powerful when used by NETCONF and YANG. This application note provides better understanding of XPath and includes examples, use cases and details on how to utilize this advanced feature. ConfD includes a full XPath implementation. Download this appnote to increase your knowledge of this advanced capability as it will help save you time and money in your network programmability efforts.
