Answer 1

だけのルート要素が存在することができます - headingとsong - 次の2つがあります。

あなたのようなものに再構築した場合：

<?xml version="1.0" encoding="UTF-8"?> 
<song> 
<heading> 
The Twelve Days of Christmas 
</heading> 
.... 
</song> 

（他の問題があるかもしれませんが）ルートレベルで整形式XMLに関するエラーが消えるはずです。

Answer 2

文字列「strOutputは」正しいXML構造を有していることを保証した後、あなたがこれを行うことができます：

Matcher junkMatcher = (Pattern.compile("^([\\W]+)<")).matcher(strOutput); 
strOutput = junkMatcher.replaceFirst("<");
