@H_502_1@我现在想通过循环一条一条地将记录数据读取出来，比如先读取<record1>下的<mageDescriptors>里面的数据，进行处理，再接着读取<record2>下的<mageDescriptors>里面的数据，进行处理，。。。以此类推。现在我在一个循环里面写了下面的代码，但是调试的时候，始终无法获取，不知道怎么回事，希望您能给我指点一下，谢谢！

@H_502_1@@H_502_1@对结构体中的“opencv-matrix”加以区别，用下面的思路就可以了

@H_502_1@@H_502_1@ CvFileNode *node;
@H_502_1@ const char* xmlfile = "your.xml";

@H_502_1@ CvFileStorage *fs = cvOpenFileStorage( xmlfile,CV_STORAGE_READ );

@H_502_1@ node = cvGetFileNodeByName (fs,NULL,"opencv-matrix_1");
@H_502_1@ imageMat_1= (CvMat *) cvRead (fs,node);
@H_502_1@ node = cvGetFileNodeByName (fs,"opencv-matrix_2");
@H_502_1@ imageMat_2 = (CvMat *) cvRead (fs,node);
@H_502_1@ ...
@H_502_1@ node = cvGetFileNodeByName (fs,"opencv-matrix_n");
@H_502_1@ imageMat_n = (CvMat *) cvRead (fs,node);

@H_502_1@ cvReleaseFileStorage (&fs);
