I work as Information Developer. 

I need to create **.dita** files with the file names stored in an excel sheet. 

The .dita files are XML files. The structure of the files should be same. The structure is as follows:

```
<?xml version="1.0" encoding="UTF-8"?>
<!--Arbortext, Inc., 1988-2011, v.4002-->
<!DOCTYPE concept PUBLIC "-//OASIS//DTD DITA Concept//EN"
"concept.dtd">
<?Pub Inc?>
<concept id="concept-1-43B80068" xml:lang="en">
<title></title><?Pub Caret -1?>
<shortdesc></shortdesc>
<conbody>
<p></p>
</conbody>
</concept>

```

and then I need to create a map of these files as follows:

```
<map xml:lang="en">
<topicref href = "topic1.dita">
<topicref href = "topic2.dita">
</topicref>
</map>

```

Please provide a solution to this.
