I am trying to convert XML to HTML but got struck with the error as :

Data at the root level is invalid. Line 1, position 1

Here is my XML file
<?xml version="1.0"?><br/>
<notification><br/>
<project>Test Project</project><br/>
</notification>
Here is my XSL file

<?xml version="1.0" encoding="ISO-8859-1"?><br/>
<!-- Edited by XMLSpy --><br/>
<html xsl:version="1.0" xmlns:xsl=" http://www.w3.org/1999/XSL/Transform http://www.w3.org/1999/XSL/Transform " xmlns=" http://www.w3.org/1999/xhtml http://www.w3.org/1999/xhtml <br/>
<body style="font-family:Arial;font-size:12pt;background-color:#EEEEEE <br/>
<xsl:for-each select="notification <br/>
<div style="background-color:teal;color:white;padding:4px <br/>
<span style="font-weight:bold <xsl:value-of select="project"/><br/>
<br/>
</xsl:for-each>
</body><br/>
</html>

Here is my method which tries to convert XML to HTML
