I'm giving you a full working example based on your input. A few notes:
Use normalize-space() and split the string by space.
Just play with substring-before and substring-after.
make sure to use xsl:strip-space.
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
>
<xsl:output omit-xml-declaration="yes" method="text"/>
<xsl:strip-space elements="*"/>
<xsl:variable name="space" select="' '"/>
<xsl:template match="block4/tag[name='50K']">
<xsl:variable name="value" select="normalize-space(value)"/>
<xsl:variable name="code" select="substring-before($value,$space)"/>
<xsl:variable name="string1" select="concat(
substring-before($code,'/'),
'/,',
substring-after($code,'/'))"/>
<xsl:variable name="string2" select="substring-before(
substring-after($value,$space),
$space)"/>
<xsl:variable name="string3" select="substring-after(
substring-after($value,$space),
$space)"/>
<xsl:value-of select="concat($string1,',',$string2,'~',$string3)"/>
</xsl:template>
<xsl:template match="name|value"/>
</xsl:stylesheet>

Your biggest problem is that value is you context node (defined in your template's match attribute), but you're referring to value in your XPath. This will look for a value node within the value node, which is obviously wrong.
In your <xsl:variable> and <xsl:value-of> statements, change refences to value to ., to refer to the current node instead.
I think that's probably not the only issue, but given that your template isn't going to match anything in that document anyway, it's difficult to derive where else it could be going wrong. One possible additional problem is that your substring-before(value,'
') predicate within your <xsl:value-of> isn't going to return anything with the formatting given, as there's a newline before the 0101/etc... Now I think about it, that's also going to be issue in the substring-after in the previous line. That's very dependent on how it's actually formatted though, but from what you've given here, it is a problem.
