# Read XML node content method example let's take a look at the implementation of C # Read XML nodes:

1. Using system;
2. Using system. xml;
3. Using system. xml. XPath;
4. Using system. DaTa;
6. Class readxml
7. {
8. Public static void main ()
9. {
10. String sfile = "readxml. xml ";
12. // C # Read the XML Node Method 1
13. Xmldocument Doc = new xmldocument ();
14. Doc. Load (sfile );
15. Xmlnode node = Doc. documentelement ["news"] ["content"];
16. Console. writeline (node. innertext );
18. // C # Read the XML node method2
19. Node = Doc. selectsinglenode ("// content ");
20. Console. writeline (node. innertext );
22. // Similarly
23. Node = Doc. documentelement. selectsinglenode ("News/content ");
24. Console. writeline (node. innertext );
26. // C # Read the XML Node Method 3
27. Dataset DS = new dataset ();
28. DS. readxml (sfile );
29. Console. writeline (Ds. Tables [0]. Rows [0] ["content"]. tostring ());
31. // C # Read the XML Node Method 4
32. Xmltextreader reader = new xmltextreader (sfile );
33. While (reader. Read ())
34. {
35. If (reader. Name = "content ")
36. {
37. Console. writeline ("***" + reader. readstring ());
38. Break;
39. }
40. }
42. Reader. Close ();
44. // C # Read the XML Node Method 5
46. Xpathdocument xpdoc = new xpathdocument (sfile );
47. Xpathnavigator xpnv = xpdoc. createnavigator ();
48. Xpnv. movetofirstchild ();
49. Xpnv. movetofirstchild ();
50. Xpnv. movetofirstchild ();
51. Xpnv. movetonext ();
52. Console. writeline ("pathnavigator:" + xpnv. value );
