How to replace "<" or ">" in xsl stylesheet?

[santaji]

I am getting xml string in request attribute in following format
&lt;files&gt ;
&lt;file&gt;
&lt;filename&gt ;somefile.ext&l t;/filename&gt;
&lt;/file&gt;
&lt;files&gt ;
the above string I want to convert to tags.
expected output after xsl transformation -
<files>
<file>
<filename>somef ile.ext</filename>
</file>
<files>

dangerous method: use disable-output-escaping
<xsl:value-of select="express ion" disable-output-escaping="yes"/>

If the input string is not well-formed the output will not be either.
