XSL: obtain value after a currency text

I have the following inputs
<Text>01 TEMP ANC FEE  USD  21.00   X23457</Text>
<Text>21 TEMP ANC FEE  CAD  10.50   X84564</Text>

I want to obtain the value right after the currency, regardless of what type of currency is being used.
I currently have

<xsl:variable name="test"
  select="
substring-before (substring-after(concat(normalize-space($Line[contains(Text, 'ANC FEE')][position() = $pos]), ' '), 'CAD '),' ')"/>
           
which returns 10.50 and as you can see only works for CAD.

How can i set this up, so that it'd return ANY value without it being currency specific?


And also, I'm curious to understand. what would be the difference between the two commands ( I see output as same)?

1. substring-before (substring-after(normalize-space($Line[contains(Text, 'ANC FEE')][position() = $pos]), 'CAD '),' ')"/>
2. substring-before (substring-after(concat(normalize-space($Line[contains(Text, 'ANC FEE')][position() = $pos]), ' '), 'CAD '),' ')"/>

Have you looked at this string manipulation article?

http://www.xml.com/pub/a/2002/05/01/xslt-string.html

Essentially, if the length prior to the actual currency amount is consistent, you can use the substring function.

The second one of the two options concats a ' ' at the end of the argument for substring.
As such it ensures that when you would have
<Text>21 TEMP ANC FEE  CAD  10.50</Text>
as input, it would still return the 10.50

The first one would not work in that occasion

About your task for making it work for both USD and CAD

<xsl:variable name="test"
  select="
substring-before (substring-after(translate(concat(normalize-space($Line[contains(Text, 'ANC FEE')][position() = $pos]), ' '), 'US', 'CA'), 'CAD '),' ')"/>

Since you are only interested in the numbers,
translate every U in a C and every D in an A and you would get away with it for this particular assignment

I make this suggestion assuming this is the only information you have about the strings,
If size is a given or the numbers of components seperated by a space, we could use other techniques

I do know that there will always be 5 components before the amount. As in my examples above.

Well, then this would be the better approach
(though likely not that readable)

   
<xsl:variable name="test"
        select="
        substring-before(substring-after(substring-after(substring-after(substring-after(substring-after(concat(normalize-space($Line[contains(Text, 'ANC FEE')][position() = $pos]), ' '), ' '), ' '), ' '), ' '), ' '),' ')
        "/>
