You need to review some basic principles of XSLT that should be easily 
available in online resources.

When you are processing the template supplied with an <xsl:for-each> 
instruction, your current node list is the collection of nodes addressed in 
the select= attribute, and the template is processed for adding to the 
result tree as many times as there are members in the current node 
list.  Each time the template is processed the next node in document order 
of the current node list becomes the current node.

Above you are not considering that your current node is already <children> 
and you only need the value of the current node, addressed using 
".".  Though best practice is to use <xsl:apply-templates/> so as to allow 
your stylesheet to be imported by other stylesheets for specialization 
purposes.  Doing this would engage the built-in template rules for the text 
of the <children> element.

So you would have:

        <xsl:for-each select = "location/name/children">
                <fo:block text-align="left">
                        <xsl:apply-templates/>
                </fo:block>
        </xsl:for-each>

I hope this helps.
