Java : Convert formatted xml file to one line string

Question

I have a formatted XML file, and I want to convert it to one line string, how can I do that.

Sample xml:

<?xml version="1.0" encoding="UTF-8"?> <books>    <book>        <title>Basic XML</title>        <price>100</price>        <qty>5</qty>    </book>    <book>      <title>Basic Java</title>      <price>200</price>      <qty>15</qty>    </book> </books> 

Expected output

<?xml version="1.0" encoding="UTF-8"?><books><book> <title>Basic XML</title><price>100</price><qty>5</qty></book><book><title>Basic Java</title><price>200</price><qty>15</qty></book></books> 

Thanks in advance.

//filename is filepath string BufferedReader br = new BufferedReader(new FileReader(new File(filename))); String line; StringBuilder sb = new StringBuilder();  while((line=br.readLine())!= null){     sb.append(line.trim()); } 

using StringBuilder is more efficient then concat http://kaioa.com/node/59
