When this XSLT:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output omit-xml-declaration="no" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="/*">
<t>
<xsl:apply-templates select="*/*[starts-with(name(), 'Carprice')]"/>
</t>
</xsl:template>
<xsl:template match="*[starts-with(name(), 'Carprice')]">
<Carfactory>
<xsl:apply-templates select="../*[self::CarName or self::Carcode]"/>
<Carprice>
<xsl:apply-templates/>
</Carprice>
<count>
<xsl:value-of select="substring-after(name(), '_')"/>
</count>
</Carfactory>
</xsl:template>
</xsl:stylesheet>
...is applied against the provided XML:
<Carfactory>
<Table>
<CarName>Veyron</CarName>
<Carcode>9196</Carcode>
<Carprice_1>64760</Carprice_1>
<Carprice_2>69760</Carprice_2>
<Carprice_3>64960</Carprice_3>
<Carprice_4>64790</Carprice_4>
<Carprice_5>64780</Carprice_5>
<Carprice_6>64860</Carprice_6>
<!-- ... -->
<Carprice_27>68760</Carprice_27>
</Table>
</Carfactory>
...the wanted result is produced:
