Add root node to xml

[SriRajesh]

Hi,
I generated xml string and want to add root node:

#lets create a dataframe
df=pd.DataFrame({'A':[1,2,3],'B':['a','b','c']})

def to_xml(df):
    def row_xml(row):
        xml = ['<item>']
        for i, col_name in enumerate(row.index):
            xml.append('  <{0}>{1}</{0}>'.format(col_name, row.iloc[i]))
        xml.append('</item>')
        return '\n'.join(xml)
    res = '\n'.join(df.apply(row_xml, axis=1))
    return(res)
1
to_xml(df)

<item>
<A>1</A>
<B>a</B
</item>
<item>
<A>2</A>
<B>b</B>
</item>
<item>
<A>3</A>
<B>c</B>
</item>
...
========================
Add root node:

<Header>
     <Name></Names>
     <Release><</software>
<Header>

<Values>
    <item>
       <A>1</A>
       <B>a</B
   </item>
   <item>
       <A>2</A>
       <B>b</B>
   </item>
   <item>
       <A>3</A>
       <B>c</B>
   </item>
<Values>
