Function parseXml

apps/sim/tools/workday/soap.ts:333–486

* Minimal XML parser tuned for Workday SOAP responses: namespaced tags, * attributes, mixed text, self-closing tags, and CDATA sections. * Not a general-purpose parser — it does not expand entities beyond the * standard five and ignores processing instructions and DOCTYPE.
