Description

Environment

  • OS Version: any
  • Source or binary build? any

Description

  • Expected behavior: if you have an SDFormat file with data in custom XML namespaces (like custom_elems_attrs.sdf), if you load the file into an sdf::Root and then write it out again with Root::ToElement(), the resulting Element-tree should also have the custom data fields.
  • Actual behavior: it does not include the custom data fields.

Steps to reproduce

  1. TODO: write code to reproduce this

Output

Contributor guide

Research direction
Investigate the ToElement() methods in the SDFormat library and trace how elements are serialized. Focus on how custom XML namespaces (xmlns attributes) are handled during output. Check if the internal Element tree stores namespace information and if it's properly written back. Write a small test to reproduce the issue by loading a file with custom namespaces and comparing the output.
