Code Review
This pull request introduces dump functions for dql/xml and dql/html to aid in debugging queries. While these methods are useful for development, they hardcode output to os.Stderr, which can lead to sensitive information exposure in production logs. The implementation includes good test cases and refactoring, such as standardizing on iter.Seq for NodeSet_Cast and using a more idiomatic way to copy slices in dql/xml/parse.go, which appear safe. There are also suggestions to make the new dump functions even more informative.

The Dump method hardcodes logging of HTML node data (including tag names, attributes, and text content) directly to os.Stderr. This can lead to the exposure of sensitive information (e.g., PII, session tokens, or secrets) in system logs if the method is used in a production environment. It is recommended to allow the caller to provide an io.Writer or to use a configurable logger instead of hardcoding os.Stderr. Additionally, to make the Dump function even more comprehensive for debugging, consider handling other common node types like html.CommentNode and html.DoctypeNode in the switch statement.

The XGo_dump method hardcodes logging of XML node data (including element names and attributes) directly to os.Stderr. This can lead to the exposure of sensitive information in system logs if used in a production environment. It is recommended to allow the caller to provide an io.Writer or to use a configurable logger instead of hardcoding os.Stderr. Additionally, for better debugging, it would be beneficial to also include the node's text content, which can be achieved using the existing Root(node).XGo_text__0() helper.

This Dump method calls the underlying NodeSet.Dump which hardcodes logging to os.Stderr. This can lead to sensitive information exposure in production logs. Consider providing a way to specify the output stream.
