推荐答案

首先需要确定的几件事:

1-您要编写的xml文件的结构，可能是这样的:

There are few things you need to decide first:

1- Structure of xml file that you want to write, it may be something like this:

<people>
<name>John</name>
<age>26</age>
</people>
<people>
<name>xyz</name>
<age>28</age>
.
.
</people>

或者您可以提出其他一些选择

2-当需要将数据写入xml文件时，在捕获一组数据之后立即或仅在捕获所有数据集结束时.

之后，您可以使用以下链接将数据写入xml文件:

希望对您有帮助...

Or you can come up with something else

2- When the data needs to be written in xml file, immediately after one set of data is captured or only at the end when all data sets are captured.

After this you can use following link to write data into xml file:

我现在有了这个:

i have this now:

private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            XmlWriter writer = XmlWriter.Create("Query_advanced.xml", settings);
            writer.WriteStartDocument();
            writer.WriteStartElement("Query");
            foreach (string item in listBox1.SelectedItems)
            {
                               
                    writer.WriteStartElement("Attribute");
                    writer.WriteAttributeString("Name", item);
                    //writer.WriteAttributeString("Name", "Patient Name");
                    writer.WriteAttributeString("Value", textBox1.Text);
                    writer.WriteEndElement();
                
                //   catch
                //{
                //    throw;
                //}
                
            }
            writer.WriteEndElement();
            writer.WriteEndDocument();
            writer.Flush();
            writer.Close();
            
        }

而且我需要在退出循环之前保存项目，然后为此每次都更新xml.我该怎么办?

And i need to save the items before coming out of the loop, and then update the xml everytime for this. How can i go about?
