Converting string(key:val) to xsl

Anyone got XSL code that'll convert a string in (key=val) format (see example)

Keep getting errors, when I try to run it that I can't diagnose due to lack of knowledge with the language.

Given: fr=me to=you do=command Num=1521739

Desire (in XSL):

<command>
    <Input>
        <Num>1521739</Num>
    </Input>
</command>

Well, given $string containing:

fr=me to=you do=command Num=1521739

you can extract the value of do as:

<xsl:value-of select="substring-before(substring-after($string, 'do='), ' ')"/>

and the value of Num as:

<xsl:value-of select="substring-after($string, 'Num=')"/>

If you don't know the order of the pairs, append a space to the string before extracting a value:

<xsl:value-of select="substring-before(substring-after(concat($string, ' '), 'Num='), ' ')"/>

Similarly, if you suspect that a key can be contained in another key, e.g.

do=command undo=option

use a leading space to select the key unambiguously:

<xsl:value-of select="substring-before(substring-after(concat(' ', $string, ' '), ' do='), ' ')"/>
