Replace part of an XML (by other XML file)

[Peter55]

Hello. I would like to replace part of an XML file by another. Up to now I have been using a mix of XSL, VBScript and ASP. Any code or relevant articles greatly appreciated. Thks and Rgds.

e.g.

1. XML looks like this:

<?xml version=&quot;1.0&quot;?>
<conferences>
<conf id=&quot;cnf1&quot; display=&quot;yes&quot;>
<field id=&quot;area&quot;>
<field_value>PT11 A</field_value>
</field>
<field id=&quot;dates&quot;>
<field_value>1-2 Jan 2003</field_value>
</field>
</conf>
<conf id=&quot;cnf2&quot; display=&quot;yes&quot;>
<field id=&quot;area&quot;>
<field_value>PT12 B</field_value>
</field>
<field id=&quot;dates&quot;>
<field_value>3-4 Jan 2003</field_value>
</field>
</conf>
</conferences>

2. I then have another XML file.
<conferences>
<conf id=&quot;cnf2&quot; display=&quot;yes&quot;>
<field id=&quot;area&quot;>
<field_value>PT12 Bb</field_value>
</field>
<field id=&quot;dates&quot;>
<field_value>13-14 Jan 2003</field_value>
</field>
</conf>
</conferences>

3. My final XML file needs to be:
<?xml version=&quot;1.0&quot;?>
<conferences>
<conf id=&quot;cnf1&quot; display=&quot;yes&quot;>
<field id=&quot;area&quot;>
<field_value>PT11 A</field_value>
</field>
<field id=&quot;dates&quot;>
<field_value>1-2 Jan 2003</field_value>
</field>
</conf>
<conf id=&quot;cnf2&quot; display=&quot;yes&quot;>
<field id=&quot;area&quot;>
<field_value>PT12 Bb</field_value>
</field>
<field id=&quot;dates&quot;>
<field_value>13-14 Jan 2003</field_value>
</field>
</conf>
</conferences>
