Note: There are several ways to determine if you are an IE browser or a non-ie browser, but here are just a few ways to use it:1, parse the XML string, the way to get the XML object:function Createxml (str) {if (document.all) {//ie browservar xmldoc = new ActiveXObject ("Microsoft.XMLDOM");Xmldoc.async = false;Xmldoc.loadxml (str);return xmldoc;}else{//Non-IE browserreturn new Domparser (). parsefromstring
Open the file and add new data at any time.
File *fp;if((fp=fopen("data.txt","a"))==NULL){printf("Create File failure"); exit(1);}fprintf(fp,"[%d, %d]\n", x, y);fclose(fp);
Cyclic operations store a lot of data as follows:
[29, 35][29, 33][30, 34][29, 33][29, 34][29, 34][29, 34][28, 33][30, 34][30, 34][29, 33][28, 33][29, 33][29, 33][29, 34][29, 33]

XML is an Extensible Markup language, in electronic computers, marking refers to the computer can understand the information symbols, through such a mark, the computer can be processed with a variety of information such as articles. It can be used to tag data, define data types, and is a source language that allows users to define their own markup language. It is ideal for world Wide Web transport, providing a unified approach to describing and exchan
easy operation. It supports deletion, modification, and re-arrangement among other functions.
Disadvantage: transferring the entire document to memory (often containing a large number of useless nodes) wastes time and space.
Usage: Once the file is parsed, you need to access the data multiple times and have sufficient resources (such as memory and CPU ).
To solve these problems caused by Dom parsing XML

. The flow model solves the problem very well, because its access to the XML file is based on the concept of a stream, that is, there is only the current node in memory at any time, but it also has its drawbacks, it is read-only, forward only, and cannot perform backward navigation in the document. ”

For example, if the Author table above already uses an automatically generated column type for the ID, the statement can be modified to: Insert into User (Id,username,password,email,bio) VALUES (#{id},#{username},#{password},#{email}) MyBatis there is another way to generate a primary key for a database that does not support auto-generated types, such as Oracle, or for JDBC drivers that might not support auto-generating primary keys. s
