I have found it advantageous to break the import process in two steps: syntax conversion and reorganization of data structure.

我发现将导入过程分成以下两个步骤是有利的：语法转换和数据结构的重新组织。

This time, you will fetch all of the import statements in the abstract syntax tree.

这一次，您可以读取抽象语法树中的所有导入声明了。

youdao

语法类似于刚刚显示的IMPORT示例，因为您在调用xmlvalidate子句时指定了一个已注册(或已完成的)XML模式。
