Answer 1

Quick hacky XSLT , tested it online it seems to work.

<?xml version="1.0"?>
    <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
        version="1.0">
        <xsl:template match="*">
            <xsl:copy>
                <xsl:apply-templates select="@*|node()" />
            </xsl:copy>
        </xsl:template>
        <xsl:template match="@*|text()|comment()|processing-instruction">
        </xsl:template>
        <xsl:template match="//part">
            <part>
                <xsl:text>00</xsl:text>
                <xsl:value-of select="."></xsl:value-of>
            </part>
        </xsl:template>
    </xsl:stylesheet>

Your possible solution might be:

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

    <xsl:output method="xml"/>

    <xsl:template match="part">
        <xsl:value-of select="format-number(., '000')"/>
    </xsl:template>

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

</xsl:stylesheet>
