Technical References - [xmlnodesattributes]

This context is used to iterate the attributes of a specific XML node.

numero = 286
interpreted = N
texte = [xmlnodesattributes ref=...&path=...] [/xmlnodesattributes] The 'path' parameter is used to locate the node. As with the [xmlnodes] context, the 'path' parameter has three modes; 'named:', 'indexed:', and 'xpath:'. Optional Tag Parameters: · ref - Reference to an xml object variable. If this parameter is not provided, then it is assumed that there is an 'outer' [xmlnode/s] context from which to reference a particular XML node. · path - Path to the desired XML node. If an XPath expression is used, it should evaluate to a single node. Optional Context Tags: · [name] - The name of the current iterated XML node attribute. · [value] - The value of the current iterated XML node attribute. · [index] - The 'count' of the current iterated attribute. · [numfound] - The total 'count' of iterated attributes.
