word域代码转换html丢失解决办法.doc

Word转html存在域代码丢失。Aspose ，jacob，poi都无法解决在使用jocob转换成html时 域代码会被包裹可以统一提取出来转换成latex ，latex转换成图片，解决word域代码丢失问题private void processFormula(List nodes) throws UnsupportedEncodingExceptionfor(int i = nodes.size()-1;i=0;i-)Node node =nodes.get(i);if(node instanceof Element)Element e = (Element)node;processFormula(e.childNodes();else if(node instanceof Comment)String commentText =
