[Python] Need help comparing XSD files. Specifically, getting the paths/names of nodes in an...

So basically I need a script to compare an Original XSD file to an edited version of it to list all the changes.

I used ChatGPT and it gave me a good result which pretty much does what I need.

But the problem is in the output the way it writes out the nodes is not human readable.

It gives something like /xs:schema/xs:complexType[50]/xs:attribute[1].

Instead I would want it to give the names of each node in the path, like A/B/C.

Each node has a name attribute so it should be possible but I’m not sure how.

The code is below, if anyone can help it would be really appreciated!

Code:

from xmldiff import main
from xmldiff.formatting import DiffFormatter
from lxml import etree

# Original Schema 1
with open("XSD_Original_Version.xsd", "r", encoding="utf-8") as file1:
schema1 = file1.read()
# Modified Schema 2
with open("XSD_SR_Version.xsd", "r", encoding="utf-8") as file2:
schema2 = file2.read()

# Parse the original schema into an ElementTree (needed by formatter)
orig_tree = etree.fromstring(schema1)
new_tree = etree.fromstring(schema2)

# Compute the diff operations
diff_ops = main.diff_trees(orig_tree, new_tree)

# Format the changes into readable text
formatter = DiffFormatter()
formatted_diff = formatter.format(diff_ops, orig_tree)

# Print the result
print("Changes from Schema1 to Schema2:\n")
for line in formatted_diff.splitlines():
if line.strip():
print(f"- {line}")



Output:

• [update-attribute, /xs:schema/xs:complexType[7]/xs:element[15], name, "Status"]
• [update-attribute, /xs:schema/xs:complexType[7]/xs:element[15], type, "xs:string"]
• [update-text-after, /xs:schema/xs:complexType[7]/xs:element[15], "\n\t\t"]
• [move, /xs:schema/xs:complexType[6]/xs:choice[2]/xs:choice/xs:element[16], /xs:schema/xs:complexType[7], 15]
• [update-attribute, /xs:schema/xs:complexType[7]/xs:element[16], name, "BusinessPhone"]
• [update-text-after, /xs:schema/xs:complexType[7]/xs:element[16], "\n\t\t"]
• [move, /xs:schema/xs:complexType[6]/xs:choice[2]/xs:choice/xs:element[75], /xs:schema/xs:complexType[7], 16]
• [update-attribute, /xs:schema/xs:complexType[7]/xs:element[17], name, "GeocodeStatusDisplay"]
• [update-text-after, /xs:schema/xs:complexType[7]/xs:element[17], "\n\t\t"]
• .......
