How to delete specific nodes from XML in Java? (DOM Manipulation)
To delete a specific node, you need to operate based on the tag name and conditions (such as attribute values or text content): the liveNodeList must be traversed in reverse order and removeChild() is called; XPath is recommended for complex conditions; be sure to check that the parent node is not empty before deleting to avoid NPE; performance and memory limitations should be considered for large-scale deletions.

How to compare two XML files and find differences
Use tools or programming methods to compare XML file differences: first use online tools (such as xmlcompare.org) or IDE plug-ins for visual comparison, and then implement automated analysis through the command line (such as xmllint diff) or Python scripts (using the lxml library to parse and standardize XML). Pay attention to the processing of whitespace characters, attribute order, namespace prefixes and other influencing factors. It is recommended to use CanonicalXML to eliminate format differences.

How to prevent XML External Entity (XXE) attacks? (Security Audit)
Disabling DTD parsing is the most effective measure to defend against XXE attacks; you should explicitly set disallow-doctype-decl to true, give priority to using JSON instead of XML, and cooperate with Schema verification, entity expansion restrictions, and pre-filtering DOCTYPE/ENTITY to strengthen protection.
