Append Header from File 1 to File 2

Shell Programming and Scripting
1

Hi All,

I am relatively new to scripting and am stuck on this problem, having tried many combinations of sed and awk.

I am generating XML files ('File 2' - 20101214_1800_111_CODE.XML) which contain XML from line 1 starting with

<REPORT>

I need to insert a header for each file from a seperate file ('File 1' - xml_header.txt) which contains the below:

<?xml version="1.0" ?>

<?xml-stylesheet type="text/xsl" href="mdd-stylesheet.xsl" ?>

I need this to be updated into File 2 as this is a dynamically named file containing date, time and version information.

File 2 after this needs to look like this:

<?xml version="1.0" ?>

<?xml-stylesheet type="text/xsl" href="mdd-stylesheet.xsl" ?>

<REPORT>

I would be grateful for any assistance on how I can do this.

grep -n will give you the line number a string appears on.
head -# will give the first n lines.

for file in `ls *CODE.XML`
do
    cat xml_header.txt $file > temp
    mv temp $file
done
