Directly read XML node attribute values

Directly read XML node attribute values

Directly read XML node attribute values
Use xpath
/Priceavailabilityresponsev10/priceavailabilityresponse/responseitemcollection/responseitems/responseitem/vendoritemlist/vendoritem/price/@ up [.]
The previous steps are the same as reading the node. Note that [.] is added to the XPath that reads the node attribute value to read the specific value of this attribute.
The advantage is that you can directly specify the specific attribute value to the XPath and read it directly through xmldocument, instead of finding the node where the attribute is located, and then reading the attribute value through the node.
