XSLT - Convert science notation number to normal format

[daydreaming]

Hi all,

I need some help to convert the number in science notation format back the normal format.

The input xml
<?xml version='1.0' encoding='utf-8'?>
<product>
<price>2.022E 9</price>
</product>

The required output xml
<?xml version='1.0' encoding='utf-8'?>
<product>
<price>20220000 00</price>
</product>

I have wrote the below code, but it did work as what I want yet.

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:styleshe et xmlns:xsl="http ://www.w3.org/1999/XSL/Transform" version="2.0">

<xsl:template match="product" >
<product>
<xsl:apply-templates/>
</product>
</xsl:template>
<xsl:template match="//price">
<price>
<xsl:value-of select='format-number(., "############## .0000")' />
<!-- Need a number with 14 digits before decimal point and 4 digits after the decimal point-->
<xsl:apply-templates/>
</price>
</xsl:template>

</xsl:stylesheet>

Thank you for any help in advance.
