XSLT: flatten tree

I'd like to convert Kodi-compatible xml to Xtreamer-compatible xml. The input looks like this:

<?xml version="1.0" encoding="utf-8"?>
<movie xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <id>something</id>
  <title>something</title>
  <originaltitle>something</originaltitle>
...and so on... several unknown nodes
  <actor>
    <name>Name1</name>
    <role>Role1</role>
    <order>0</order>
  </actor>
  <actor>
    <name>Name2</name>
    <role>Role2</role>
    <order>1</order>
  </actor>
  <actor>
    <name>Name3</name>
    <role>Role3</role>
    <order>2</order>
  </actor>
...several other unknown nodes...
</movie>

What I'd like to have is:

<?xml version="1.0" encoding="utf-8"?>
<movie xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <id>something</id>
  <title>something</title>
  <originaltitle>something</originaltitle>
...and so on... several unknown nodes
  <actor>
    <name>Name1</name>
    <name>Name2</name>
    <name>Name3</name>
  </actor>
...several other unknown nodes...
</movie>

...so just drop every child item of actor besides name and put all the names into one common actor tag. The rest of the document should stay unchanged.

What I tried is:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns="http://www.w3.org/TR/REC-html40">

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

<xsl:template match="/movie">
 <actor>
 <xsl:for-each select="actor">
 <xsl:apply-templates select="name"/>
 </xsl:for-each>
 </actor>
 <xsl:apply-templates/>
 </xsl:template>


</xsl:stylesheet>

What I get is:

<?xml version="1.0"?>
<actor xmlns="http://www.w3.org/TR/REC-html40"><name xmlns="">Name1</name><name xmlns="">Name2</name><name xmlns="">Name3</name></actor>
<id>something</id>
<title>something</title>
<originaltitle>something</originaltitle>
...and so on... several unknown nodes
<actor>
<name>Name1</name>
<role>Role1</role>
<order>0</order>
</actor>
<actor>
<name>Name2</name>
<role>Role2</role>
<order>1</order>
</actor>
<actor>
<name>Name3</name>
<role>Role3</role>
<order>2</order>
</actor>
...several other unknown nodes...

Some things don't work work like wanted:

1. All the actor-nodes and their children are still in the output.
2. The actor-name-name-name-actor-Block:
   • replaces the movie-tag
   • is in the beginning, not at the position, where the actor-nodes used to be before
   • has no line breaks

Any help would be appreciated.
