XML文档切片技术

XML文件作为一种数据存储与数据交换的文件，其应用日益广泛，但目前对于信息量大、结构复杂的文档要获取其中有用信息的操作效率较低。现提出一种新的基于程序切片技术对XML文档进行切片的方法。对给定的XML文档，可根据给定的切片规则对文档进行切片，从而得到一个用户感兴趣信息集合的新XML文档。同样，也可以对给定的XML文档对应的DTD或XML模式文档进行切片，根据给定的切片规则生成新的DTD或XML模式文档切片，同时，也会生成对应的XML文档切片，且切片获得的新文档是符合新的DTD或XML模式规范的有效文档。

Slicing XML Documents Technique

XML files are widely used in saving and exchanging data applications, but most of the current methods which obtain useful information from the XML file with huge data and complex structure perform poor in efficient. A XML slice method which is based on the program slicing technique to solve this problem is presented. In terms of the slicing criterion, slicing a given XML document can get a new XML document which including the information set you interested. Analogously to the XML slicing, slicing a given DTD or XML schema document also can get a new DTD or XML schema document and a new XML document which is valid respect to the new DTD or XML schema.
