Summary of Changes

Hello @luoliwoshang, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request updates a demo application to reflect changes in the libxml2 library's API, specifically for version 2.15. The primary change involves transitioning the xmlFreeDoc call from a standalone function to a method invoked directly on the XmlDoc object. This ensures the demo remains compatible and correctly handles document memory deallocation with the updated library version.

Highlights

• libxml2 API Update: The pull request updates the usage of the libxml2 library, specifically adapting to changes in how xmlFreeDoc is called.
• Method Call Adoption: The xmlFreeDoc function call has been refactored from a global function libxml2.XmlFreeDoc(doc) to a method call doc.XmlFreeDoc() on the XmlDoc object, aligning with the libxml2v2.15 API.

Code Review

This pull request updates the parsexml demo to use the new method-based API for xmlFreeDoc from what appears to be a new version of libxml2. The change correctly identifies the move from a package-level function to a method. However, there's an inconsistency in the implementation that likely leads to a compile error. The new method should be called on the docPtr variable, which is cast to the correct type, for correctness and consistency with other method calls in the file. I've added a comment with a suggestion to fix this.

[xgopilot]

Overall Assessment: The PR successfully demonstrates the transition to method-style API calls for libxml2 v2.15, which improves code idiomaticity. The change from libxml2.XmlFreeDoc(doc) to doc.XmlFreeDoc() is functionally correct with no performance or security concerns.

Minor Issue: There's an inconsistency where docPtr is used for one method call but doc is used for another (see inline comment).
