摘要
为了实现 STEP的 XML 表达 ,以 STEP Part2 1物理文件为研究对象 ,首先分析了 EXPRESS与 XML 语言并建立匹配关系 ;然后建立基于数据实例层次结构树的 XML DTD以实现通用的、统一的 XML表达 ;最后结合原型系统 SX_ Viewer的实现过程和结果证明其可行性和实用性 .
In order to realize the representation of STEP with XML, taking STEP part21 file as primary reference, we established the correlation between EXPRESS and XML. In order to realize the generalized representation, we created XML DTD which was based on the hierarchical tree structure for data instance. At last, with the help of SX _Viewer, the process and result of conversion example is presented to verify the feasibility and practicability of this approach.
