Abstract
XML is a kind of advanced network markup language,and SVG is an open vector graph describable language based on XML.SVG is used to describe some kinds of graphs in text in WebGIS.This paper,through making some DOM objects,realizes visiting and inquiring SVG data document,and edits SVG characters.So we can manage SVG document data and interact with map to get some information.
