Answer 1

You can use format-number function as below:
<xsl:value-of select="format-number(.//accountNumber, '#')"/>
Result:
111118800

Answer 2

In XSLT 2 or later you can use replace(., '^0+', '') in the context of xsl:template match="accountNumber" to remove leading zeros with string operations (http://xsltfiddle.liberty-development.net/3Nqn5Y3/1) or you can use xs:integer(.) to remove the leading zeros by converting that value inside of element to an integer (http://xsltfiddle.liberty-development.net/3Nqn5Y3).
