title: Match all lines starting with a space up till a line that doesnt start with a space
body: <p>So I have a few lines like such:</p>
  
  <pre><code>tag1:
   line1word1 lineoneanychar
   line2word1
  tag2:
   line1word1 ....
   line2word1 .....
  </code></pre>
  
  <p>I am trying to build a java regex that extracts all the data under the tags. i.e:</p>
  
  <pre><code>String parsed1 = line1word1 lineone\nline2word1
  String parsed2 = line1word1 ....\nline2word1 .....
  </code></pre>
  
  <p>I believe the right way to do this is using something like this, but I haven't quite got it right:</p>
  
  <pre><code>    Pattern p = Pattern.compile("tag1:\n( {1}.*)\n(?!\\w+)", Pattern.DOTALL);
      Matcher m = p.matcher(clean_data);
      if(m.find()){
          System.out.println(m.group(1));
      }
  </code></pre>
  
  <p>Any help would be appreciated!</p>
