asp.net 的xml数据增删改查的相关文章

Salesforce零基础（三）简单的数据增删改查页面的构建(Ajax样式)

VisualForce封装了很多的标签用来进行页面设计 下面以一个单一的表进行数据增删改查.表结构如图1所示.通过图可以看出GOODS表自己定义的参数主要包括以下: GoodsName__c,GoodsType__c,GoodsBrand__c,GoodsDescribe__c,GoodsPrice__c. 图1 VF每个页面都是以<apex:page>标签起始</apex:page>结束,每个VF页面都有一个Controller用来控制其业务逻辑.本篇例子中主要用到的控件包括如下

flex 操作xml 实现增删改查 .

一 在介绍Flex中操作XML之前,首先简单介绍下XML中的基本术语. 元素:XML中拥有开始标签和结束标签的这一块称为“元素”    节点:把XML元素与文本结合起来统称为节点    根节点:位于整个XML文当顶端的节点    文本节点:包含文本的节点    属性:元素的组成部分,以键/值形式放在元素标签内 用一个例子来说明 view plaincopy to clipboardprint?<root_node><!--这是一个根节点也是一个元素-->            &l

三种方式实现数据增删改查

ASP.NET WebAPI --- 简单实现增删改查

先理解一下WebAPI的概念,官方给的很详细: 什么是Web API? 在我们了解什么是Web API之前,让我们看看什么是API(应用程序编程接口). 根据维基百科的API定义:在计算机编程中,应用程序编程接口(API)是一组用于构建软件和应用程序的子例程定义,协议和工具. 简单来说,API是某种接口,它具有一组允许程序员访问应用程序,操作系统或其他服务的特定功能或数据的功能. Web API顾名思义,是一个可以使用HTTP协议访问的Web上的API.这是一个概念,而不是一种技术.我们可以使用

jeesite应用实战（数据增删改查）

jeesite配置指南(官方文档有坑,我把坑填了!)这篇文章里,我主要把jeesite官方给出的帮助文档的坑填了,按照里面的方法可以搭建起来jeesite的站点.系统可以运行以后,就可以进入开发模块了,我们先从数据的增删改查做起. 一.页面效果 很简单,涉及到的就是数据的增删改查. 二.如何利用jeesite做呢? 上面我们也看到了,功能很简单,那么怎么利用jeesite做呢?jeesite能给我们提供什么便利呢? 第一步.建表 利用jeesite之前,要先建数据表. 至于怎么建表,方法太多了,

函数、文件操作实现数据增删改查---low版本

首先说明这个脚本很low,目前水平有限,只能实现使用固定的语法对数据进行增删改查.但是现在脚本不low,怎么让明年的我来嘲笑今年的自己 需求    a.可进行模糊查询,语法至少支持下面3种:  select name,age from staff_table where age > 22  select  * from staff_table where dept = "IT"      select  * from staff_table where enroll_date l

C#在winform中操作数据库，实现数据增删改查

1.前言: 运行环境:VS2013+SQL2008+Windows10 程序界面预览: 使用的主要控件:dataGridview和menuStrip等. 2.功能具体介绍: 1.首先,我们要先实现基本的数据操作,增删改查这几个操作. (1)先定义一个数据库操作的公共类: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks

xml解析——增删改查操作后将其修改结果保存

一.可扩展标记语言xml:Extensible Markup Language    1.XML的作用:1)统一数据传输的格式.2)做小型数据库[文件型数据库].3)做配置文件  .ini   .propertity  .xml  .cfg    2.XML文件的基本格式:      标签:分为双标签和单标签,双标签的开头和结尾标签名必须一致,大小写一样,/ 开头的是结尾标签,单标签必须在 > 前加上 / 来结尾,单标签中不能放文本.      属性:在开始标签中定义一些名值对,值一定是字符串 

java中XML操作：xml与string互转、读取XML文档节点及对XML节点增删改查

一.XML和String互转: 使用dom4j程式变得很简单 //字符串转XML String xmlStr = \"......\"; Document document = DocumentHelper.parseText(xmlStr); // XML转字符串 Document document = ...; String text = document.asXML(); //这里的XML DOCUMENT为org.dom4j.Document 二.读取XML文档节点: pack
