XSL: obtain value after a currency text

Posted on 2013-12-11
Last Modified: 2013-12-11
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"
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?

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"
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"
        substring-before(substring-after(substring-after(substring-after(substring-after(substring-after(concat(normalize-space($Line[contains(Text, 'ANC FEE')][position() = $pos]), ' '), ' '), ' '), ' '), ' '), ' '),' ')
