TextWrangler - removing namespaces from XML

Question

I'm working with TextWrangler's find and replace function. I have a folder of XML files that all include this tag:

<song xmlns="http://openlyrics.info/namespace/2009/song" version="0.8" createdIn="OpenLP 2.0.1" modifiedIn="OpenLP 2.0.1" modifiedDate="2013-06-23T21:33:21">

I would like to remove the namespaces and other info from the tag and get just this:

<song>

My issue is twofold:

1. First, I can't get TextWrangler to find anything that includes angle brackets. I don't know how to search for a literal angle bracket.
2. The modifiedDate= part of the tag is different for each file. Therefore, I need something that will find all text contained in the tag, no matter what it says.

Any suggestions?

It's really worth acquiring sufficient familiarity with XSLT for this kind of task. Doing it in a text editor will always have limitations (for example your code is quite likely to depend on the attributes being in a particular order). It's probably as simple as this:

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="*">
  <xsl:element name="{local-name()}">
    <xsl:apply-templates/>
  </xsl:element>
</xsl:template>

</xsl:transform>

This will in fact remove namespaces and attributes from all elements, not just the song element, but this can easily be changed by adding another template rule.
