How do you remove blank lines from an XML document or node using C#?

Question

I want all the blank lines to be removed in the XML below before writing it to document. It may help to know that I used the .DeleteSelf() method of the XPathNavigator class to get rid of the unwanted nodes before (and that only leaves empty lines).

    <Person xmlns="http://someURI.com/something">
      <FirstName>Name1</FirstName>











       <MiddleName>Name2</MiddleName>


       <LastName>Name3</LastName>




     </Person>

Answer 1

I'd suggest to use XDocument class:

1. method:

string xcontent = @" strange xml content here ";
XDocument xdoc = XDocument.Parse(xcontent);
xdoc.Save("FullFileName.xml");

2. method:

XmlReader rdr = XmlReader.Create(new StringReader(xcontent));
XDocument xdoc = XDocument.Load(rdr);
xdoc.Save("FullFileName.xml");

returns:

<Person xmlns="http://someURI.com/something">
  <FirstName>Name1</FirstName>
  <MiddleName>Name2</MiddleName>
  <LastName>Name3</LastName>
</Person>
