Reading and Writing XML files

1. Write XML (create an XML file ):
Xmltextwriter mywriter = new xmltextwriter (file path, null );
// Document version 1.0 for writing XML
Mywriter. writestartdocument ();
// Write Start Element
Mywriter. writestartelement ("root ");
// Write Element
Mywriter. writestartelement ("");
Mywriter. writestring ("Tale ");
Mywriter. writeendelement ();

Mywriter. writestartelement ("B ");
Mywriter. writestring ("th ");
Mywriter. writeendelement ();

Mywriter. writestartelement ("C ");
Mywriter. writestring ("T3 ");
Mywriter. writeendelement ();

// Write the end document
Mywriter. writeenddocument ();
// Close the stream and save it in the file
Mywriter. Close ();

2. Read XML:

Xmlreader xmlr = xmlreader. Create (file path );
Xmlr. movetocontent ();
Xmlr. Read ();
If (xmlr. Name. tostring () = "databasename ")
{
Databasename = xmlr. readinnerxml (). tostring ();
// Read other elements in sequence
.........
}

In addition:
Xmlreader xmlr = xmlreader. Create ("ftp_set.xml"); // open the document to be read
Xmlr. movetocontent ();
While (xmlr. Read () // read cyclically
{
Switch (xmlr. Name. tostring ())
{
Case "Uri": // xml tag
This. strftpuri = xmlr. readinnerxml (). tostring ();
Break;
Case "potnumber ":
Strpotnum = xmlr. readinnerxml (). tostring ();
Break;
Case "username ":
This. strusername = xmlr. readinnerxml (). tostring ();
Break;
Case "password ":
This. strpassword = xmlr. readinnerxml (). tostring ();
Break;
}
}

3. Note: when reading XML, if the file contains blank spaces and press enter, a blank space and press enter will be read at a time. You can program to ignore these spaces and press Enter.
