[C#/COMMON/.NET6] XmlTextWriter 클래스 : XML 포맷 정규화하기

■ XmlTextWriter 클래스를 사용해 XML 포맷을 정규화하는 방법을 보여준다.

▶ XmlTextWriter 클래스 : XML 포맷 정규화하기 예제 (C#)


string xml = "<?xml version=\"1.0\"?><response><error code=\"1\"> Success</error></response>";

Console.WriteLine(NormalizeXMLFormat(xml));

/*
<?xml version="1.0"?>
<response>
    <error code="1"> Success</error>
</response>
*/

string xml = "<?xml version=\"1.0\"?><response><error code=\"1\"> Success</error></response>";

Console.WriteLine(NormalizeXMLFormat(xml));

<?xml version="1.0"?>

<error code="1"> Success</error>

</response>
