<xsl:for-each select="block4/tag[name = '72']">
    <xsl:value-of select="
        concat((concat(
        substringafter(value,'//'),'')),
        substringbefore(value,'/'))

Give this a try:

substring-before(substring-after(value,'//'),'/')

EDIT

@bluish how can i get this value ABNAAFU000000D93--16.560-10

I guess it's a new question. So here you have:

substring-before(substring-after(substring-after(value,'//'),'/'),'/')

I hope you've learnt the concepts behind these solutions. Take a look at this good and simple reference.
