摘　　要：XML是针对网络应用的一项新技术。当越来越多的信息存为XML文档时,就需要构造一种方式,通过接口获取信息。这就需要一种方法来确定文档各个部分之间的关系,以及访问一个与其他资源有关的文档的内部各部分。XPath,XLink和XPointer这3种语言都可以用来访问数据。其中,XPointer用来确定文档个别部分的位置,XPath与XSLT和XPointer一起使用来对XML文档各部分进行定位,而XLink则用来与XML文档链接。XML is a new technology directed against network application. When more and more information is stored as XML documents, it is needed to construct a way to obtain information through the interface. This needs a kind of method to confirm the relation among each part of a document,and visits every inside part of a document related to other resources. XPath, XLink and XPointer- these three languages can all be used for visiting the data. Among them, XPointer is used for eonfirmiug the position of the specific part of a doctanent. XPath can together with XSLT and XPointer for orienting every part of an XML document. XLink is used for linking an XML document. This article introduces the thee and carries on comparative analysis to them.
