Parse an xml file to extract element values using lxml and XPath in python
I have this xml file and I want to extract the values associated with certain specific elements. More specifically what I want is when the element value is Marks then check if next element value is Marks of Student(They are towards the end of the in the sample xml I have shown below ). If it is then extract/print these two tags and next 3 tags(which would be Minimum,Maximum, and Mean values):
<?xml version="1.0"?>

Currently I have this code where I am using ElementTree as to parse the xml file but it is not producing any output(it doesn't print anything).
import io
import xml.etree.ElementTree
tree = xml.etree.ElementTree.parse('xmlFile1.xml').getroot()
parent_map = {c: p for p in tree.getiterator() for c in p}
def search_data(first_text, next_text):
data_with_marks = [data_node
for data_node in tree.findall(".//Data")
if data_node.text == first_text]
for marks_elem in data_with_marks:
cell_elem = parent_map[marks_elem]
row_elem = parent_map[cell_elem]
cell_nodes = list(row_elem)
curr_index = cell_nodes.index(cell_elem)
next_index = curr_index + 1
next_data_node = next(iter(cell_nodes[next_index]))
if next_data_node.text == next_text:
return [next(iter(cell_node))
for cell_node in cell_nodes[curr_index:curr_index + 6]]
return []
if __name__ == '__main__':
for node in search_data("Marks", "Marks of Student"):
print(node.text)
I am trying to look for lxml and XPath but don't know how to do that. How can I modify my current code to use lxml and XPath to parse the xml file and get the output I want?

Here is a way to extract the wanted information with ElementTree:
from xml.etree import ElementTree as ET
NSMAP = {"ss": "urn:schemas-microsoft-com:office:spreadsheet"}
tree = ET.parse("xmlFile1.xml")
# Find all Row elements
rows = tree.findall(".//ss:Row", NSMAP)
# For each Row, get all Data 'grandchildren'
for row in rows:
data = row.findall("ss:Cell/ss:Data", NSMAP)
if data and len(data) == 5:
# If first two Data elements are what we want, print out all Data element values
if data[0].text == "Marks" and data[1].text == "Marks of Student":
for d in data:
print (d.text)
Output:
Marks
Marks of Student
0
96
65.71
The default namespace is urn:schemas-microsoft-com:office:spreadsheet, and the elements you are interested in are in this namespace. That's why we need to use the NSMAP dictionary. See https://docs.python.org/3/library/xml.etree.elementtree.html#parsing-xml-with-namespaces.
