c# - Formatting XML with tabulation and removing element ending space? -

i trying 2 things:

1. get output xml formated tabulation instead of spaces.

2. remove ending space generates video element.

   " /> 

   to

   "/> 

i have tried use

xmlwriter.formatting = formatting.indented; 

as as

indentchar 

but did not worked me dont know why.

this code have currently, hear advices , suggestion improve it:

xmldocument xmldoc = new xmldocument();  xmltextwriter xmlwriter = new xmltextwriter(filename, system.text.encoding.utf8); xmlwriter.writeprocessinginstruction("xml", "version='1.0' encoding='utf-8' standalone='yes'"); xmlwriter.writecomment(@" file made @author"); xmlwriter.writestartelement("videos"); xmlwriter.close();  xmldoc.load(filename); xmlnode root = xmldoc.documentelement; foreach (int myid in exportlistids) {     xmlelement video = xmldoc.createelement("video");     root.appendchild(video);     video.setattribute("videoid", myid.tostring()); }  xmldoc.save(filename); 

i have managed solve question 1 below code still don't know if possible remove space between " , /> @ end of element vide question 2.

        xmlwritersettings settings = new xmlwritersettings();         settings.encoding = encoding.utf8;         settings.indent = true;         settings.indentchars = "\t";          xmlwriter writexml = xmlwriter.create("test.xml", settings);         writexml.writestartdocument();         writexml.writecomment(@" file made @author");          writexml.writestartelement("videos");          foreach (var item in mylist)         {             writexml.writestartelement("video");             writexml.writeattributestring("id", item.key.tostring());             writexml.writeattributestring("name", item.value);                 writexml.writestartelement("object");                 writexml.writeattributestring("a", item.key.tostring());                 writexml.writeattributestring("b", item.value);                 writexml.writeendelement();             writexml.writeendelement();         }          writexml.writeendelement();         writexml.writeenddocument();         writexml.close();
