XML Interview Questions

Can you walk us through the steps necessary to parse XML documents?

Superficially, this is a fairly basic question. However, the ball is not to determine whether candidates understand the concept of a parser but rather have them walk through the process of parsing XML documents step-by-step. Determining whether a non-validating or validating parser is needed, choosing the appropriate parser, and handling errors are all important aspects to this process that should be included in the candidate's response.
