自定义XML求高手帮忙解决下呀十万火急！！！！！！！！！！！！

Question

是这样的！要实现自定义一个XML 也就是内存中的，不是实际的XML文件,
xmlDocument 然后自己往这里面 给一个根结点，
然后再根结点下面指定添加子节点，最后将这个 xmlDocument 对象保存到数据库中某表中的某个字段中去，
结里在数据库表中的字段可以看到如下效果  <?xml version="1.0" encoding="utf-8"><newPricture><pic><href>href1</href></pic><pic><href>href1</href></pic><pic><href>href1</href></pic></newPricture>就如同一个真实的XML文件...

Answer 1

XmlNode node = xmlDocument.CreateElement("节点名")
xmlDocument.append(node);
类似这样的写法

Answer 2

<?xml version="1.0" encoding="utf-8">
这个声明 也要加进去呀！！！

Answer 3

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXML("<?xml version=\"1.0\" encoding=\"utf-8\">");
XmlNode node = xmlDocument.CreateElement("newPricture")
xmlDocument.AppendNode(node); 

Answer 4

你说的是创建一个XML。我已前做过一次，能看懂多少，就是多少吧。 private void create_empty_movie_xml()
        {
            
                XmlDocument xmldoc = new XmlDocument();
                XmlNode xmlnode = xmldoc.CreateNode(XmlNodeType.XmlDeclaration, "", "");
                xmldoc.AppendChild(xmlnode);
                XmlElement xmlelem = xmldoc.CreateElement("", "KeyFrames", "");
                xmldoc.AppendChild(xmlelem);
                XmlElement xmlSubElem;
                XmlAttribute xmlAttr;
                int totalSoundLength = 0;
                for (int i = 0; i < dialogueSoundID.GetLength(0); i++)
                {
                    xmlSubElem = xmldoc.CreateElement("", "Sounds", "");
                    xmlAttr = xmldoc.CreateAttribute("ID");
                    xmlAttr.Value = dialogueSoundID[i, 0].ToString();
                    xmlSubElem.Attributes.Append(xmlAttr);
                    if (dialogueSoundID[i, 1] == 1)
                    {
                        xmlAttr = xmldoc.CreateAttribute("soundPath");
                        xmlAttr.Value = "\\tasks\\" + GlobalValue.taskID.ToString() + "\\sounds" + "\\" + dialogueSoundID[i, 0].ToString() + ".wav";
                        xmlSubElem.Attributes.Append(xmlAttr);
                        xmlAttr = xmldoc.CreateAttribute("soundLength");
                        xmlAttr.Value = dialogueSoundID[i, 2].ToString();
                        totalSoundLength = totalSoundLength+ dialogueSoundID[i, 2];
                        xmlSubElem.Attributes.Append(xmlAttr);
                    }
                    else
                    {
                        xmlAttr = xmldoc.CreateAttribute("soundPath");
                        xmlAttr.Value = "";
                        xmlSubElem.Attributes.Append(xmlAttr);
                        xmlAttr = xmldoc.CreateAttribute("soundLength");
                        xmlAttr.Value = "0";
                        xmlSubElem.Attributes.Append(xmlAttr);
                    }
                    xmlAttr = xmldoc.CreateAttribute("playerID");
                    xmlAttr.Value = dialogueSoundID[i, 3].ToString();
                    xmlSubElem.Attributes.Append(xmlAttr);
                    xmlelem.AppendChild(xmlSubElem);
                }
                XmlElement xmlSpeElem = xmldoc.CreateElement("", "wholeSound", "");
                XmlAttribute xmlAttrSpe = xmldoc.CreateAttribute("soundPath");
                xmlAttrSpe.Value = "\\tasks\\" + GlobalValue.taskID.ToString() + "\\sounds" + "\\" + outputSoundFileName;
                xmlSpeElem.Attributes.Append(xmlAttrSpe);
                xmlAttrSpe = xmldoc.CreateAttribute("soundLength");
                xmlAttrSpe.Value = totalSoundLength.ToString();
                xmlSpeElem.Attributes.Append(xmlAttrSpe);
                xmlelem.AppendChild(xmlSpeElem);
                try
                {
                    xmldoc.Save(taskPath + "\\movie_xml.xml");
                }
                catch (Exception er)
                {
                    Console.WriteLine(er.Message);
                }
            
        }

Answer 5

最后我要把 xmlDocument   这个对象保存到数据库的呀！！！
然后数据库表的字段就可以看到一个XML格式的字符串。。

Answer 6

直接把XmlDocuemnt的InnerXML取出来不就可以了。。
不会是保存数据库也不会把

Answer 7

 StringBuilder sb = new StringBuilder();
            XmlWriterSettings setting = new XmlWriterSettings();
            setting.Encoding = Encoding.UTF8;
            setting.Indent = true;
            setting.OmitXmlDeclaration = false;
            XmlWriter writer = XmlWriter.Create(sb,setting);//XML编写器,有几个重载,根据自己需要选用
            writer.WriteStartElement("根节点");
            writer.WriteAttributeString("Name", "abc");            writer.WriteStartElement("子节点一");//开如子节点
            writer.WriteAttributeString("Name", "one");//属性,第一个参数是属性名,第二个参数是属性值
            writer.WriteEndElement();//结束子结点            writer.WriteStartElement("子节点二");
            writer.WriteAttributeString("Name", "two");
            writer.WriteEndElement();            writer.WriteEndElement();//结束根结点
            writer.Close();
            Console.WriteLine(sb.ToString());//显示XML内容显示:
<?xml version="1.0" encoding="utf-16"?>
<根节点 Name="abc">
  <子节点一 Name="one" />
  <子节点二 Name="two" />
</根节点>

Answer 8

大家请看我是循环所有图片信息  myDiv_Img  是我获取到的所有图片地址
 XmlDocument xmlDoc = new XmlDocument(); 
foreach (Match mImg in mcImg)
                {
                myDiv_Img = mImg.Groups["src"].Value + "\n";             
                  XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "GB2312",  null); 
  //手动添加一个声明              
  xmlDoc.AppendChild(dec); 
                //创建根节点
                  XmlElement root = xmlDoc.CreateElement("Pricture"); 
                xmlDoc.AppendChild(root); 
                
                XmlNode pic = xmlDoc.CreateElement("pic"); 
                XmlElement title = xmlDoc.CreateElement("href"); 
                title.InnerText = myDiv_Img;
                pic.AppendChild(title); 
                showXML = myDoc.InnerText;为 什么showXML 取不到值本来我是要取到值了然后插到数据库的。。  我是个新手希望大家指点下， 真的很急

Answer 9

你既然定义了节点pic那怎么不将它append到root下面呀.还有读取的时候怎么可以直接读myDoc呀。试试下面的root.AppendChild(pic); 
            XmlNode readNode = myDoc.SelectSingleNode("/Pricture/pic/href");
            showXML = readNode.InnerText; 

Answer 10

看错了，root.AppendChild(pic); 不用加了

Answer 11

不好意思刚有行代码少写了 root.AppendChild(pic); 
这个我是有加进去的
我就是不知道怎么读取 xmlDocument 的值
试下 showXML = readNode.InnerText 看行不。

Answer 12

那下面也得改：XmlNode readNode = myDoc.SelectSingleNode("/pic/href");
            showXML = readNode.InnerText; 

Answer 13

楼上的朋友说的是可以取到值不过只是图片地址的值呀！！ 例如取到的是 
http://img10.360buyimg.com/S1/1627/19cc4bdc-239f-4f76-9325-dc156a1b7a8c.jpg
而我要的是整个 xmlDocument 里面的所有内容保存在数据库
 例如
<?xml version="1.0" encoding="utf-8"> <newPricture> <pic> <href>href1 </href> </pic> <pic> <href>http://img10.360buyimg.com/S1/1627/19cc4bdc-239f-4f76-9325-dc156a1b7a8c.jpg </href> </pic> <pic> <href>http://img10.360buyimg.com/S1/1627/19cc4bdc-239f-4f76-9325-dc156arewa8c.jpg </href> </pic> </newPricture> 我要实现这样的效果。。

Answer 14

看10楼的.也可以把刚才的改成。
            StringBuilder sb = new StringBuilder();
            XmlWriterSettings setting = new XmlWriterSettings();
            setting.Encoding = Encoding.UTF8;
            setting.Indent = true;
            setting.OmitXmlDeclaration = false;
            XmlWriter writer = XmlWriter.Create(sb, setting);
            //加入以前内容
            myDoc.WriteContentTo(writer);
            showXML = sb.ToString()

Answer 15

 StringBuilder sb = new StringBuilder(); 
            XmlWriterSettings setting = new XmlWriterSettings(); 
            setting.Encoding = Encoding.UTF8; 
            setting.Indent = true; 
            setting.OmitXmlDeclaration = false; 
            XmlWriter writer = XmlWriter.Create(sb, setting); 
            
            XmlDocument xmlDoc = new XmlDocument(); 
           
             XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "GB2312",  null); 
             xmlDoc.AppendChild(dec); 
                //创建根节点 
                XmlElement root = xmlDoc.CreateElement("Pricture"); 
                xmlDoc.AppendChild(root); 
                
                XmlNode pic = xmlDoc.CreateElement("pic"); 
                root.AppendChild(pic);                 XmlElement title = xmlDoc.CreateElement("href"); 
                title.InnerText = "hello"; 
                pic.AppendChild(title);                XmlNode readNode = xmlDoc.SelectSingleNode("/Pricture/pic/href");                xmlDoc.WriteContentTo(writer);
                writer.Close();
                Console.WriteLine(sb.ToString());//显示XML内容
完整代码。测试过了。结果：
<?xml version="1.0" encoding="GB2312"?>
<Pricture>
  <pic>
    <href>hello</href>
  </pic>
</Pricture>

Answer 16

谢谢楼上的差不多可以了但是还有点小问题
我运行完却是这种效果<?xml version="1.0" encoding="GB2312"?>
<Pricture>
  <pic>
    <href>http://img10.360buyimg.com/S5/1874/3b0d418c-26f7-4ac4-a6a3-84f5a47e35b2.jpg</href>
  </pic>
</Pricture><?xml version="1.0" encoding="GB2312"?>
<Pricture>
  <pic>
    <href>http://img10.360buyimg.com/S5/3565/16387575-ca4a-4201-9227-fa094505df9b.jpg</href>
  </pic>
</Pricture>这是我源代码 StringBuilder sb = new StringBuilder();
foreach (Match mImg in mcImg)
                {
                    myDiv_Img = mImg.Groups["src"].Value + "";
                    XmlWriterSettings setting = new XmlWriterSettings();
                    setting.Encoding = Encoding.UTF8;
                    setting.Indent = true;
                    setting.OmitXmlDeclaration = false;
                    XmlWriter writer = XmlWriter.Create(sb, setting);
                    XmlDocument xmlDoc = new XmlDocument();
                    XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "GB2312", null);
                    xmlDoc.AppendChild(dec);
                    //创建根节点 
                       XmlElement root = xmlDoc.CreateElement("Pricture");
                    xmlDoc.AppendChild(root);
                    XmlNode pic = xmlDoc.CreateElement("pic");
                    root.AppendChild(pic);
                    XmlElement title = xmlDoc.CreateElement("href");
                    title.InnerText =myDiv_Img;
                    pic.AppendChild(title);
                    XmlNode readNode = xmlDoc.SelectSingleNode("/Pricture/pic/href");
                    xmlDoc.WriteContentTo(writer);
                    writer.Close(); 
                }
                 showXML = sb.ToString();

Answer 17

改下foreach (Match mImg in mcImg)的位置就行：
                StringBuilder sb = new StringBuilder();
                myDiv_Img = mImg.Groups["src"].Value + "";
                XmlWriterSettings setting = new XmlWriterSettings();
                setting.Encoding = Encoding.UTF8;
                setting.Indent = true;
                setting.OmitXmlDeclaration = false;
                XmlWriter writer = XmlWriter.Create(sb, setting);
                XmlDocument xmlDoc = new XmlDocument();
                XmlDeclaration dec = xmlDoc.CreateXmlDeclaration("1.0", "GB2312", null);
                xmlDoc.AppendChild(dec);
                //创建根节点 
                XmlElement root = xmlDoc.CreateElement("Pricture");
                xmlDoc.AppendChild(root);
                foreach (Match mImg in mcImg)
                {
                XmlNode pic = xmlDoc.CreateElement("pic");
                root.AppendChild(pic);
                XmlElement title = xmlDoc.CreateElement("href");
                title.InnerText = myDiv_Img;
                pic.AppendChild(title);
                }
                xmlDoc.WriteContentTo(writer);
                writer.Close();
            
                showXML = sb.ToString();
