XMl Write file method (summarized according to Multi-person-tracking article)

XmlTextWriter write a file, the default is to overwrite the previous file, if the file name does not exist, it will create this file, first create the XML file format

1.

XmlTextWriter myXmlTextWriter = new XmlTextWriter (".. \.. \xxx.xml ", NULL);

2. Use the Formatting property to specify what format you want to set the XML to. Elements like this can be indented by using the indentation and IndentChar properties.

myXmlTextWriter.Formatting = formatting.indented;

The elements can then be created using the WriteStartElement and WriteElementString methods, the difference being that if there are elements of a child node, then it is created with writestartelement and then to create the element

Once created, call the appropriate writeendelement to tell the compiler, create a single element with writeelementstring, and create the attribute with WriteAttributeString. as follows:

   1:xmltextwriter myXmlTextWriter = new XmlTextWriter (@ "... \..
   \book1.xml ", NULL); 2://Use the Formatting property to specify what format you want to set the XML to.
   In this way, child elements can be indented by using the indentation and IndentChar properties.
   3:myxmltextwriter.formatting = formatting.indented;
   4:5: Myxmltextwriter.writestartdocument (FALSE);
   6:myxmltextwriter.writestartelement ("bookstore");
   7:8: myXmlTextWriter.WriteComment ("Information for recording books");
  9:myxmltextwriter.writestartelement ("book");
  10:11:myxmltextwriter.writeattributestring ("Type", "elective");
  12:myxmltextwriter.writeattributestring ("ISBN", "111111111");
  13:14:myxmltextwriter.writeelementstring ("Author", "Zhang San");
  15:myxmltextwriter.writeelementstring ("title", "career Plan");
  16:myxmltextwriter.writeelementstring ("Price", "16.00");
  17:18:myxmltextwriter.writeendelement ();
  19:myxmltextwriter.writeendelement (); 20: 
  21:myxmltextwriter.flush (); 22:myxmltextwriter.close ();

Raise:

WriteStartDocument () method

WriteStartDocument becomes the writer validation, and you are writing a well-formed XML document. For example, he checks that the XML declaration is the first node, and that only one root-level element exists, and so on.

If this method is not called, the writer assumes that an XML fragment is being written and does not apply any root-level rules.
