Scala Language XML Handling Beautify or Pretty-Print XML
Example
The PrettyPrinter utility will 'pretty print' XML documents. The following code snippet pretty prints unformatted xml:
import scala.xml.{PrettyPrinter, XML}
val xml = XML.loadString("<a>Alana<b><c>Beth</c><d>Catie</d></b></a>")
val formatted = new PrettyPrinter(150, 4).format(xml)
print(formatted)
This will output the content using a page width of 150 and an indentation constant of 4 white-space characters:
<a>
Alana
<b>
<c>Beth</c>
<d>Catie</d>
</b>
</a>
You can use XML.loadFile("nameoffile.xml") to load xml from a file instead of from a string.
