# import the built-in Python module for processing XML files
Try
Import Xml.etree.cElementTree as ET
Except Importerror:
Import Xml.etree.ElementTree as ET

#准备XML字符串数据
Xml_data_str = "<?xml version=" 1.0 "encoding=" Utf-8 "?>
<!--comments--

# Prepare parsing XML string
if __name__ = = "__main__":
# Get the root node of XML
Xml_root = et.fromstring (XML_DATA_STR)
# Displays information about the output root node
Print ("=========== root node information ============")
Print ("Root node Name:", Xml_root.tag)
Print ("Root node Properties:", Xml_root.attrib)

# Get book node information
Book_list = Xml_root.findall ("book")
For x in Book_list:
Print ("Name:", X.find ("First Name"). Text)
Print ("", X.find ("author"). Text)
Print ("Price:", X.find ("price"). Text)
