Formatting string (Removing leading zeros)

Question

I am newbie to xslt. My requirement is to transform xml file into text file as per the business specifications. I am facing an issue with one of the string formatting issue.

Answer 1

Just use this simple expression:

number(.)

Here is a complete example:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="text"/>

 <xsl:template match="t">
      <xsl:value-of select="number(.)"/>
 </xsl:template>
</xsl:stylesheet>

When applied on this XML document:

<t>0001295</t>

the wanted, correct result is produced:

1295

---

II. Use format-number()

format-number(., '#')

Answer 2

There are a couple of ways you can do this. If the value is entirely numeric (for example not a CSV line or part of a product code such as ASN0012345) you can convert from a string to a number and back to a string again :

string(number($value)).

Otherwise just replace the 0's at the start :

replace( $value, '^0*', '' )

The '^' is required (standard regexp syntax) or a value of 001201 will be replaced with 121 (all zero's removed).

Hope that helps. Dave
