Question

I have a method which returns a String with a formatted xml. The method reads the xml from a file on the server and parses it into the string:

Esentially what the method currently does is:

  private ServletConfig config;
  InputStream xmlIn = null ;
  xmlIn = config.getServletContext().getResourceAsStream(filename + ".xml") ; 
  String xml = IOUtils.toString(xmlIn);
  IOUtils.closeQuietly(xmlIn);
  return xml;  

What I need to do is add a new input argument, and based on that value, continue returning the formatted xml, or return unformatted xml.

What I mean with formatted xml is something like:

<xml>
  <root>
    <elements>
       <elem1/>
       <elem2/>
    <elements>
  <root>
</xml>

And what I mean with unformatted xml is something like:

<xml><root><elements><elem1/><elem2/><elements><root></xml>

or:

<xml>
<root>
<elements>
<elem1/>
<elem2/>
<elements>
<root>
</xml>

Is there a simple way to do this?

Answer 1

Strip all newline characters with String xml = IOUtils.toString(xmlIn).replace("\n", ""). Or \t to keep several lines but without indentation.
