add elements

Hello,

thank you Joerg, now I got all the tags. 
I get the right result when using saxon and the task line. But I don`t get the result using xml-spy. Are there any options to change?

I start my xml file with this template:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="xml" version="1.0" encoding="ISO-8859-1" indent="yes"/>
<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>

but still don`t know how to continue, what to use where.

This is my xml file. It consists of numerous entries. Some entries do have the Element <UbNummer> and some don`t. I want to ask something like that: Every entry which does not contain the element <UbNummer> gets a new Element <texteintrag>. 

<entry>
		<MAT matid="687714453w">
			<Sachgebiete></Sachgebiete>
			<Fundstelle>
				<Band>1</Band>
				<Lektion>1</Lektion>
				<LektionsKategorie>X</LektionsKategorie>
				<AbsolutePos>1</AbsolutePos>
				<IndividPos>10816</IndividPos>
				<UbNummer>1</UbNummer>
			</Fundstelle>
	</MAT>
	<LO><LO>
</entry>
...

This is the result I would like to get:

<entry>
	<texteintrag>
		<MAT matid="687714453w">
			<Sachgebiete></Sachgebiete>
			<Fundstelle>
				<Band>1</Band>
				<Lektion>1</Lektion>
				<LektionsKategorie>X</LektionsKategorie>
				<AbsolutePos>1</AbsolutePos>
				<IndividPos>10816</IndividPos>
			</Fundstelle>
	</MAT>
	<LO></LO>
     </texteintrag>	
</entry>

Thanks in advance.

Elke
