一个MATLAB 写xml 文件的例子

我是靠谱客的博主坚强大米，这篇文章主要介绍一个MATLAB 写xml 文件的例子，现在分享给大家，希望可以做个参考。

最近在做project的时候需要处理大量的XML，发现不仅省事，而且效率极高。

下面是我在CSDN上发现一个兄弟自己写的用matlab写xml的代码。

于是决定取百家之长,特此转载，希望造福一方啊

复制代码

tempname = 'myxml';

docNode = com.mathworks.xml.XMLUtils.createDocument('obj')
docRootNode = docNode.getDocumentElement;
%docRootNode.setAttribute('attr_name','attr_value');

IDNode = docNode.createElement('ID'); 
    IDNode.appendChild(docNode.createTextNode(sprintf('%i',5)));
    docRootNode.appendChild(IDNode);
    
    objNmNode = docNode.createElement('objNm'); 
    objNmNode.appendChild(docNode.createTextNode(sprintf('plane####################1008')));
    docRootNode.appendChild(objNmNode);

thisElement = docNode.createElement('FDs'); 
    docRootNode.appendChild(thisElement);
    
        dataNode = docNode.createElement('FD1');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        dataNode = docNode.createElement('FD2');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        dataNode = docNode.createElement('FD3');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        dataNode = docNode.createElement('FD4');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        
        
    thisElement = docNode.createElement('FD_Clusters'); 
    docRootNode.appendChild(thisElement);
    
        dataNode = docNode.createElement('FD_Clusters1');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        dataNode = docNode.createElement('FD_Clusters2');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        dataNode = docNode.createElement('FD_Clusters3');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
        dataNode = docNode.createElement('FD_Clusters4');
        dataNode.appendChild(docNode.createTextNode(sprintf('4 43 3 32 1 6 0 3 1 2   ')));
        thisElement.appendChild(dataNode);
        
    
    FD_histoNode = docNode.createElement('FD_histogram'); 
    FD_histoNode.appendChild(docNode.createTextNode(sprintf('17 10 8 5 3 2 1 ')));
    docRootNode.appendChild(FD_histoNode);

docNode.appendChild(docNode.createComment('this is a comment'));

xmlFileName = [tempname,'.xml'];
xmlwrite(xmlFileName,docNode);
type(xmlFileName);

xmlFileName = [tempname,'.xml'];
xmlwrite(xmlFileName,docNode);
type(xmlFileName);

生产XML文件如下：
