Replace parts of string on line using XSLT 2

I have a WSDL, in which I would like to override the soap address location using XSLT 2.0.

For example: <soap:address location="http://ift.tt/1lLWWjm"/>

For the location attribute, I would like 1) xyz.company.com to become abc.company.com 2) myapp to become xyzapp.

I have written the following xslt:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://ift.tt/tCZ8VR" version="2.0" xmlns:soap="http://ift.tt/KIQHA2" xmlns:soapenc="http://ift.tt/wEYywg" xmlns:wsdl="http://ift.tt/LcBaVt">

    <xsl:output method="xml"/>


    <xsl:template match="node()|@*">
        <xsl:copy>
        <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
    </xsl:template>

    <xsl:variable name="vLocation" select="wsdl:definitions/wsdl:service/wsdl:port/soap:address/@location"/>
    <xsl:template match="@location">

      <xsl:attribute name="location">
          <xsl:value-of select="replace($vLocation, xyz.company.com', 'abc.company.com')"/> 
      </xsl:attribute>
    </xsl:template>

</xsl:stylesheet>

This works for replacing point 1 -> xyz.company.com to become abc.company.com.

But how can I also replace point 2. -> myapp to become xyzapp

Please advise.

Thanks,
