域代码转换html丢失解决办法

Word转html存在域代码丧失。Aspose，jacob，poi都无法解决在使用jocob转换成html时域代码会被<!--[ifsupportFields]><!—[endif]-->包裹可以统一提取出来转换成late*，late*转换成图片，解决word域代码丧失问题privatevoidprocessFormula(List<Node>nodes)throwsUnsupportedEncodingE*ception{for(inti=nodes.size()-1;i>=0;i--){ Nodenode=nodes.get(i);if(nodeinstanceofElement){ Elemente=(Element)node;
