Import data (read file and read string)

Local file country_data.xml

<?XML version= "1.0"?><Data>    <Countryname= "Liechtenstein">        <Rank>1</Rank>        < Year>2008</ Year>        <GDPPC>141100</GDPPC>        <Neighborname= "Austria"direction= "E"/>        <Neighborname= "Switzerland"direction= "W"/>    </Country>    <Countryname= "Singapore">        <Rank>4</Rank>        < Year>2011</ Year>        <GDPPC>59900</GDPPC>        <Neighborname= "Malaysia"direction= "N"/>    </Country>    <Countryname= "Panama">        <Rank>68</Rank>        < Year>2011</ Year>        <GDPPC>13600</GDPPC>        <Neighborname= "Costa Rica"direction= "W"/>        <Neighborname= "Colombia"direction= "E"/>    </Country></Data>

Reading XML from a file

Import= et.parse ('country_data.xml'= Tree.getroot ()

Reading XML from a string

Root = et.fromstring (country_data_as_string)

Element.tag, Element.text and Element.attributes

# Root.tag Read tag name # Root.attrib Read Attributes # root[0][1].rank Reading text values print root.tag         # output root node element <data> tag name: Dataprint root.attrib      # output root node element <data> attributes (null value): {} print root[0][2].text  # Output The text value of the first <country> sub-element <gdppc>: 141100

Element.iter ()

# root.iter (' neighbor ') find all descendant elements  for  in Root.iter ('neighbor'):    Print neighbor.attrib

Find () and FindAll ()

# Find () returns the first child element print root.find ('country')#  Fund () returns all child elements  Print root.findall ('country')
