Which of the following function programmatically extract parts of XML file?

[amp_mcq option1=”XmlSApply” option2=”XmlApply” option3=”XmlSApplyData” option4=”All of the mentioned” correct=”option4″]

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".
