Regex in xsl:analyze-string

Hi All,
I need your help in matching a string, which looks like
<TYPE>,,<TYPE2> in the input xml. The separator here is comma. There may or may not be values in between some of the commas, i.e., the input string may be like no text,,<TYPE2> or <TYPE>,,no text. I need to match the no text area also.

INPUT:
$blockValue = "no text,no text,<TYPE2>,no text"

Code:

<KEYWDBLOCK BLOCK="3">
<VALUE>
<xsl:value-of select="$blockValue"/></VALUE>
<xsl:analyze-string select="$blockValue" regex="([A-Z0-9\-\s]+)">
<xsl:matching-substring>
 
<KEYWD BLOCK="3">
<xsl:value-of select="."/>
</KEYWD>
 
</xsl:matching-substring>
</xsl:analyze-string>
</KEYWDBLOCK>

PRESENT OUTPUT:

Code:

<KEYWDBLOCK BLOCK="3">
<VALUE>,,&lt;TYPE2&gt;,</VALUE>
<KEYWD BLOCK="3">TYPE2</KEYWD>
</KEYWDBLOCK>

REQD. OUTPUT:

Code:

<KEYWDBLOCK BLOCK="3">
<VALUE>,,&lt;TYPE2&gt;,</VALUE>
<KEYWD BLOCK="3"></KEYWD>
<KEYWD BLOCK="3"></KEYWD>
<KEYWD BLOCK="3">TYPE2</KEYWD>
<KEYWD BLOCK="3"></KEYWD>
</KEYWDBLOCK>

Any help is appreciated.

Thanks in advance

I think you're better off here using tokenize():

Code:

<xsl:for-each select="tokenize($blockValue, ',')">
  <KEYWD BLOCK="3">
     <xsl:value-of select="."/>
  </KEYWD>
</xsl:for-each>
