If you are using XSL 2.0, this should work:


Input file:
<elem>"foo, bar", baz, bom</elem>


Transform file:
<xsl:transform version="2.0"
  exclude-result-prefixes="xsd xsi xsl"

  xmlns:xsd="http://www.w3.org/2001/XMLSchema"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"

>

  <xsl:output method="xml" version="1.0"
    media-type="text/xml" encoding="utf-8"
    omit-xml-declaration="yes" indent="yes"
  />

  <xsl:variable name="regex">
    <xsl:text>\s*("[^"]*"|[^,]+)\s*</xsl:text>
  </xsl:variable>

  <xsl:template match="/">
    <root>
      <xsl:analyze-string regex="{$regex}" select="/elem">
        <xsl:matching-substring>
          <token><xsl:value-of select="regex-group(1)"/></token>
        </xsl:matching-substring>
      </xsl:analyze-string>
    </root>
  </xsl:template>

</xsl:transform>


Output file:
<root>
   <token>"foo, bar"</token>
   <token>baz</token>
   <token>bom</token>
</root>
