Padding number with leading zeros in XSLT 1.0
Another approach is
substring(string(1000000000000000 + $x), 2)
I need to pad this with leading zeros to a length of 15 in the output (
That would be
substring(
concat('000000000000000', msg:BankAccount/msg:Counter),
string-length(msg:BankAccount/msg:Counter) + 1,
15
)
It can be also done using string-format
<xsl:value-of select="format-number(msg:BankAccount/msg:Counter, '000000000000000')" />
in general:
<xsl:value-of select="format-number(number_you_would_like_to_padd, 'string_how_much_zeros_you_would like')" />
