gradle9+ groovy.util.XmlParser not found

[ZiySir]

Before this PR

Gradle 9 已正式移除 groovy.util.XmlParser、groovy.util.Node 等旧的 XML 解析类。
当前代码仍依赖这些被移除的类，导致在 Gradle 9 环境下出现 ClassNotFoundException，无法完成编译与构建。

因此必须迁移到 Groovy 4+ 提供的现代命名空间 groovy.xml.*。

After this PR

该 PR 完成以下内容：

• 将所有 groovy.util.XmlParser、groovy.util.Node、groovy.util.NodeList 等引用迁移为 groovy.xml.*。
• 不改变任何解析逻辑或功能，仅替换包路径。
• 确保项目能够在 Gradle 9 + Groovy 4 环境下正常构建与运行。
• 保证向前兼容 Groovy 4 的 API，无行为变更。

==COMMIT_MSG==
Migrate deprecated XML classes for Gradle 9 compatibility

Gradle 9 removes legacy Groovy XML classes under groovy.util.*.
This commit replaces:

• groovy.util.XmlParser → groovy.xml.XmlParser
• groovy.util.Node → groovy.xml.Node
• groovy.util.NodeList → groovy.xml.NodeList

No functional changes. Ensures the project builds successfully on Gradle 9 / Groovy 4.
==COMMIT_MSG==

Possible downsides?

• 如果有外部依赖仍显式引用 groovy.util.XmlParser，可能需要一起升级。
• 项目运行环境必须基于 Groovy 4+；否则新版包路径不可用。
• 理论上无行为变更，但若使用反射访问旧包路径，需同步调整。
