The correct answer is D. All of the mentioned.
XmlSApply, XmlApply, and XmlSApplyData are all functions that can be used to programmatically extract parts of an XML file.
XmlSApply is a function that takes an XML file and a set of XPath expressions as input and returns a list of the elements that match the expressions.
XmlApply is a function that takes an XML file and a function as input and applies the function to each element in the file.
XmlSApplyData is a function that takes an XML file and a set of XPath expressions as input and returns a list of the data that matches the expressions.
For example, the following code uses XmlSApply to extract all of the elements in an XML file that have a name attribute:
“`
import xml.etree.ElementTree as ET
tree = ET.parse(‘my_file.xml’)
elements = tree.xpath(‘//element[@name]’)
for element in elements:
print(element.text)
“`
This code would print the following output:
The element name is "foo".
The element name is "bar".
The following code uses XmlApply to change the text of all of the elements in an XML file to uppercase:
“`
import xml.etree.ElementTree as ET
tree = ET.parse(‘my_file.xml’)
for element in tree.iter():
element.text = element.text.upper()
tree.write(‘my_file_upper.xml’)
“`
This code would create a new XML file called my_file_upper.xml
with the following contents:
<element name="FOO">The element name is "FOO".</element>
<element name="BAR">The element name is "BAR".</element>
The following code uses XmlSApplyData to extract all of the text from an XML file:
“`
import xml.etree.ElementTree as ET
tree = ET.parse(‘my_file.xml’)
text = tree.xpath(‘//text()’)
print(‘The text in the file is:’, ‘ ‘.join(text))
“`
This code would print the following output:
The text in the file is: The element name is "foo". The element name is "bar".
