To select the Module element in your source document you need
<xsl:stylesheet xmlns:m="http://xmlns.oracle.com/Forms">
...
<xsl:template match="m:Module">
...
and similarly for any other element in this namespace. An unprefixed name in a match pattern or XPath expression always refers to an element that is in no namespace; to refer to an element in a namespace, whether or not it is the default namespace, you need an explicit prefix.
