Java : Convert formatted xml file to one line string

Run it through an XSLT identity transform with <xsl:output indent="no"> and <xsl:strip-space elements="*"/>

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output indent="no" />
    <xsl:strip-space elements="*"/>
    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

It will remove any of the non-significant whitespace and produce the expected output that you posted.

//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
