What about this?

step1 (as described by others):
  translate('550e8400-e29b-41d4-a716-446655440000','-','0')

step2:
  <xsl:variable name="inp"
    select="'550e84000e29b041d40a7160446655440000'"/>
  <xsl:value-of select="concat(substring($inp, 1, 8),'-',
                               substring($inp,10, 4),'-',
                               substring($inp,15, 4),'-',
                               substring($inp,20, 4),'-',
                               substring($inp,25,12))"/>


$ xsltproc uuid.xsl uuid.xsl
550e8400-e29b-41d4-a716-446655440000

Subject:    Re: [xsl] replacing of characters based on position



well, Its part of the requirement where i have replace 0 in place of '-',
so that when we get this uuid back, we will replace '0' with '-'.
         The reason of this mq is replacing - with 0 because - is not a
right hexadecimal value. before droping this uuid in mq, i want to replace
it with 0 then once i get the response from mq i want to replace 0 with -
so that i will make sure that uniqueness of uuid.
