Select all nodes that are selected by this XPath expression. If multiple nodes match, multiple nodes will be returned. Nodes will be returned in document-order,

参数：

path -

node -

namespaces - Namespaces that need to be available in the xpath, where the key is the prefix and the value the namespace URI

返回：
