Transform Exception. Adding Attribute after Sub-element - xslt

Question

I have this XML:
<root>
<tab name="Detail">
<section name="mysection">
<items level="1">
<Idx_name>9</Idx_name>
<Type>mytype</Type>
<item name="myname">
<Grams um="(g)">9,0</Grams>
<Pre-infusion>Max</Pre-infusion>
</item>
<Std._Mode>On</Std._Mode>
<Price>100</Price>
</items>
</section>
</tab>
</root>
and this XSLT:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()">
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:apply-templates select="node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="items/*">
<xsl:choose>
<xsl:when test="not(name()='item')">
<xsl:attribute name="{name()}"><xsl:value-of select="."/></xsl:attribute>
</xsl:when>
<xsl:otherwise>
<xsl:copy>
<xsl:copy-of select="#*"/>
<xsl:value-of select="."/>
</xsl:copy>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
Now, what I want is:
<root>
<tab name="Detail">
<section name="mysection">
<items level="1" Idx_name="9" Type="mytype" Std._Mode="On" Price="100">
<item name="myname">9,0Max</item>
</items>
</section>
</tab>
</root>
I obtain the error: "An attribute cannot be added after a child"
Unluckily, I can not change the order of elements in the node items of my original XML
How can I do it ?
Thanks

Make sure you process the elements first you want to transform into attributes e.g. with XSLT 2.0 where you can process sequences which have a order you can simply do
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#*, node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="items">
<xsl:copy>
<xsl:apply-templates select="#*, * except item, item"/>
</xsl:copy>
</xsl:template>
<xsl:template match="items/*[not(self::item)]">
<xsl:attribute name="{name()}" select="."/>
</xsl:template>
<xsl:template match="items/item">
<xsl:copy>
<xsl:apply-templates select="#*"/>
<xsl:value-of select="."/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
With XSLT 1.0 you would need to spell out several apply-templates in the order you want.
