xml - Add tag <hour> that will contain time hh:mm from date -

i have xml

<?xml version="1.0" encoding="iso-8859-1"?> <output> <orders> <order> <id>1</id> <number>10002</number> <type>loading</type> <date>2013-01-01t02:30:00</date> </order> <order> <id>2</id> <number>10003</number> <type>loading</type> <date>2013-01-01t010:30:00</date> </order> <order> <id>3</id> <number>10004</number> <type>loaded</type> <date>2013-01-01t12:30:00</date> </order> </orders> <quantities> <quantity> <id_order>1</id_order> <unit>kg</unit> <value>1000</value> </quantity> <quantity> <id_order>1</id_order> <unit>pal</unit> <value>3</value> </quantity> <quantity> <id_order>1</id_order> <unit>m3</unit> <value>1.5</value> </quantity> <quantity> <id_order>2</id_order> <unit>kg</unit> <value>2000</value> </quantity> <quantity> <id_order>2</id_order> <unit>pal</unit> <value>4</value> </quantity> <quantity> <id_order>3</id_order> <unit>kg</unit> <value>5000</value>  </quantity> </quantities> </output> 

i need extract time date of every order , put in new tag after date. i've managed create tag

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>     <xsl:strip-space elements="*"/>    <xsl:template match="@* | node()">       <xsl:copy>          <xsl:apply-templates select="@* | node()"/>       </xsl:copy>    </xsl:template>    <xsl:template match="date">       <xsl:copy-of select="."/>       <hour> <xsl:value-of select="substring(output/orders/order/date,12,5)"/>         </hour>    </xsl:template> </xsl:stylesheet> 

but doesn't work, cant' show time in new tag.

can me please?

br

current context element <date> already, can use . instead of output/orders/order/date here :

<xsl:value-of select="substring(.,12,5)"/>
