So I have an input file that uses my company's namespace in the default namespace (xmlns="companyURL") but I want my output file to use something other than the default namespace (xmlns:cmp="companyURL"). So I construct my file using the cmp namespace, but then I want to copy some of the inner elements:
<xsl:element name="cmp:container">
<xsl:for-each select="foo">
<xsl:copy-of select="." />
</xsl:for-each>
</xsl:element>
Unfortunately, what this does is define the default namespace for each of those inner elements, making the file incredibly verbose and ugly. Simplified example:
Source:
<foo xmlns="companyURL">
<num1>asdf</num1>
<num2>ghjkl</num2>
</foo>
Turns into:
<cmp:container xmlns:cmp="companyURL">
<num1 xmlns="companyURL">asdf</num1>
<num2 xmlns="companyURL">ghjkl</num2>
</cmp:container>
Of course, companyURL is big and long and ugly, and it's the same in both places, so I would prefer the above result to just be the following:
<cmp:container xmlns:cmp="companyURL">
<cmp:num1>asdf</cmp:num1>
<cmp:num2>ghjkl</cmp:num2>
</cmp:container>
Is there an easy way to do this, or should I convert everything under the cmp namespace to the default namespace? I would prefer to use the explicit namespace naming if possible, it aids in understanding the XSLT in my experience.

You can change the default namespace within a particular element by adding an xmlns attribute to the element. Example 4-4 is an XML document that initially sets the default namespace to http://www.w3.org/1999/xhtml for all the XHTML elements. This namespace declaration applies within most of the document.
The standard way to transform XML data into other formats is by Extensible Stylesheet Language Transformations (XSLT). You can use the built-in XSLTRANSFORM function to convert XML documents into HTML, plain text, or different XML schemas. XSLT uses stylesheets to convert XML into other data formats.
XSLT Elements The namespace name http://www.w3.org/1999/XSL/Transform is used primarily to identify elements which serve as declarations or instructions in the XSLT language.
Here, the last two templates match the ns:IRenvelope and all the elements with namespace http://www.mnv.com/elc/sap , respectively. Using the xsl:element and its namespace attribute, we can create the new elements with desired namespace.
This transformation:
<xsl:template match="*">
<xsl:element name="cmp:{name()}" namespace="CompanyURL">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<xsl:template match="/*">
<cmp:container xmlns:cmp="CompanyURL">
<xsl:copy-of select="@*"/>
<xsl:apply-templates/>
</cmp:container>
</xsl:template>
</xsl:stylesheet>
when performed on the provided XML document:
<foo xmlns="companyURL">
<num1>asdf</num1>
<num2>ghjkl</num2>
</foo>
produces the wanted, correct result:
<cmp:container xmlns:cmp="CompanyURL">
<cmp:num1>asdf</cmp:num1>
<cmp:num2>ghjkl</cmp:num2>
</cmp:container>
