Lets assume it is an XML which is also defining XML Namespaces we would check and analyse as described here:
XML Extraction - Handling Namespaces (Tableau, Soap, OASIS types) - Help / Community - UiPath Community Forum

Lets demonstrate it also on a sample like this:

Name analysis
grafik

so we set the default Namespace
grafik

and can do e.g.

For looping over all sanctionEntity elements:

xDoc.root.Descendants(xnsDefault + "sanctionEntity")
