Subject: Finding best way to pretty print XML files

Havn't found best soultion to pretty print XML:

REXML: It has pp functionality, but it wrap elements like <a>content</a>
to
<a>
content
</a>

Nokogiri: there is a approch to pp, see ex:

# Pretty print XML
require "nokogiri"

def write(buffer)

  xsl =<<XSL
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" encoding="UTF-8" indent="yes"/>

<xsl:strip-space elements="*"/>
<xsl:template match="/">
  <xsl:copy-of select="."/>
</xsl:template>

</xsl:stylesheet>
XSL

    doc = Nokogiri::XML(buffer)
    xslt = Nokogiri::XSLT(xsl)
    out =  xslt.transform(doc)
    out.to_xml
end

But nokogiri has another problem, which unwrap CDATA.

Any better solution? Thanks. And apologize for my poor english.
