Test some conditions using XSL 1.0

1) How to check if the number variable has only 4 digits using XSL1.0.

<xsl:variable name="number" select="0715" />

2) How to check if the version variable has a numeric digit followed by an upper case using XSL1.0

<xsl:variable name="version" select="V1" />

1) How to check if the number variable has only 4 digits using XSL1.0.

<xsl:variable name="number" select="0715" />

This is impossible, because the value of $number is exactly the same as if you wrote

<xsl:variable name="number" select="715" />

The insignificant zero disappears long before you can test for its presence. So perhaps you just want ($number &lt; 10000)?

On the other hand, if you're testing that a string comprises exactly four digits, use translate($x, '0123456789', '9999999999') = '9999'.

2) How to check if the version variable has a numeric digit followed by an upper case using XSL1.0

Depends a little what you mean by "followed" - can there be anything in between? If you mean 'immediately followed', then you can use the same trick:

translate(substring($x, 1, 1), '0123456789', '9999999999') = '9' 
 and 
translate(substring($x, 2, 1), 'ABCD...XYZ', 'Z') = 'Z'

  1. Use the string-length() function to determine the ... well, the length of a string.

  2. You could test for:

    translate($version, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789', 'AAAAAAAAAAAAAAAAAAAAAAAAAA0000000000') = 'A0'

Note: This tests for a single upper case character followed by a single digit - IOW, the string "V1" passes this test.

Note also that your variable points to an element named V1, not to a string containing "V1".
