Java – a simple way to remove headers from XML files

I need to remove non - XML tags from a file generated by another program

The document reads as follows:

Executing Command - Blah.exe ...
-----Command Output-----
HTTP/1.1 200 OK
Connection: close
Content-Type: text/xml

<?xml version="1.0"?>
<testResults>
  <finalCounts>
    <right>7</right>
    <wrong>4</wrong>
    <ignores>0</ignores>
    <exceptions>0</exceptions>
  </finalCounts>
</testResults>

Exit-Code: 15

How to easily delete non XML text in Java?

Solution

// getContent() returns the complete text to strip.

// getContent() returns the complete text to strip.
//
String s = getContent();

// Find the start of the XML content using the <?xml prefix.
//
int xmlIndex = s.indexOf( "<?xml" );

// Strip the non-XML header.
//
s = s.substring( xmlIndex );

// Find the last closing angle-bracket; should indicate end of the XML.
//
xmlIndex = s.lastIndexOf( ">" );

// Strip everything after the closing angle-bracket.
//
s = s.substring( 0,xmlIndex );
