增加一个整型数据

#include

void main()
{
    mxml_node_t *xml;    /* */
    mxml_node_t *data;   /* */
    mxml_node_t *node;   /* */
    mxml_node_t *group;  /* */

    xml = mxmlNewXML("1.0");

    data = mxmlNewElement(xml, "data");

        node = mxmlNewElement(data, "node");
        mxmlNewText(node, 0, "val1");
       
        node = mxmlNewElement(data, "node");
        mxmlNewInteger(node, 5);
        //
        node = mxmlNewElement(data, "node");
        mxmlNewText(node, 0, "val2");
        node = mxmlNewElement(data, "node");
        mxmlNewText(node, 0, "val3");

        group = mxmlNewElement(data, "group");

            node = mxmlNewElement(group, "node");
            mxmlNewText(node, 0, "val4");
            node = mxmlNewElement(group, "node");
            mxmlNewText(node, 0, "val5");
            node = mxmlNewElement(group, "node");
            mxmlNewText(node, 0, "val6");

        node = mxmlNewElement(data, "node");
        mxmlNewText(node, 0, "val7");
        node = mxmlNewElement(data, "node");
        mxmlNewText(node, 0, "val8");
    FILE *fp;
    //mxml_node_t *tree;

    fp = fopen("filename.xml", "w");
    mxmlSaveFile(xml, fp, MXML_NO_CALLBACK);
    fclose(fp);

return ;
}
