xsd & xml with element order change

Question

I've an xml file which i have bound to an xsd schema. I want to create an xsl for the schema in such a way that whatever order i write the xml in it comes printed out in that order for example:

'<employee>
<firstname>sultan</firstname>
<lastname>saadat</lastname>
</employee>'

If the above block is written like this:

 <employee>
    <lastname>saadat</lastname>
    <firstname>sultan</firstname>
    </employee>

It should come out in the same way when transformed and not in the wayy it is parsed? what could be the possible solutions?

having trouble with this xml file

    <?xml version="1.0" encoding="UTF-8"?>

Sample Stylesheet for one section, same goes for other sections:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/resume">
    <xsl:value-of select="/resume/contact-information/full-name"/>
    <xsl:value-of select="/resume/contact-information/address_line_1"/>
    <xsl:value-of select="/resume/contact-information/address_line_2"/>
    <xsl:value-of select="/resume/contact-information/city"/>
    <xsl:value-of select="/resume/contact-information/state"/>
    <xsl:value-of select="/resume/contact-information/country"/>
    <xsl:value-of select="/resume/contact-information/phone"/>

    <xsl:for-each select="/resume/professional-experience-section/company"> 
        <!--for company name-->
        <xsl:value-of select="name"/>
        <xsl:value-of select="city"/>, <xsl:value-of select="state"/>
        <xsl:value-of select="country"/>
        <!--loop into job title-->
        <xsl:for-each select="job-title"> 
            <!--for job title-->
            <xsl:value-of select="title"/> 
            <!--for job start date and job end date-->
            <xsl:value-of select="start-date"/> – <xsl:value-of
                select="end-date"/>
            <!--Loop into job description-->
            <xsl:for-each select="job-description"> 
                <!--loop into each bullet point-->
                <xsl:for-each select="bullet-point">
                    <xsl:value-of select="statement"/>
                </xsl:for-each>
            </xsl:for-each>
        </xsl:for-each>
    </xsl:for-each>

Answer 1

There's many ways, but they tend to boil down to looping through tags that are "either lastname or firstname" in order. One example would be

<xsl:for-each select="firstname|lastname">
  <xsl:value-of select=".">
</xsl:for-each>
