<property name="city">Bangalore</property>

I want to search by the key name and if the property name is country. I have to replace the value by Africa and the result should look like below.

<property name="country">Africa</property>
<property name="city">Bangalore</property>

Answer 1

xml_example.xml file

<root_1>
    <property name="country">India</property>
    <property name="city">Bangalore</property>
</root_1>

code:

import xml.etree.ElementTree as ET

tree = ET.parse("xml_example.xml")
for property in tree.iter('property'):
    if property.attrib['name'] == "country" and property.text == "India":
    property.text = "Africa"
tree.write("xml_example.xml")

Output:

<root_1>
    <property name="country">Africa</property>
    <property name="city">Bangalore</property>
</root_1>

Answer 2

Code:

from lxml import etree as xml
xml_str="""
<note>
<property name="country">India</property>
<property name="city">Bangalore</property>
</note>
"""
xm=xml.fromstring(xml_str)

for a in xm.iter():
    if a.tag == "property" and a.attrib.get("name") == "country":
        a.text = "Africa"
print xml.tostring(xm)

Output:

<note>
<property name="country">Africa</property>
<property name="city">Bangalore</property>
</note>

Notes:

• I have used lxml to parse and to modify the XML object _ I iterate through each element using the for loop
• I check if the element is a property element and also if it has a name attribute whose value is country
• If so then have changed it's value to Africa
• This code is in Python 2.+
