For-each in XSL

My XML -
<location id="texas">
  <name>Jim</name>
        <children>tommy</children>
        <children>pam<children>
        <children>sam<children>
   </name>
</location>

I need to get to print the chilrens name in a page on a new line 

 The number of children can vary so I need to get all the children, when I
use a for-each tag I am not able to access it.
        
<xsl:for-each select = "location/name/children">
                <fo:block text-align="left">
                <xsl:value-of select = "location/name/children"/>
                </fo:block> 
        </xsl:for-each>


Any help ?
