Companies House xml gateway & dreamweaver

I am a newbie to this Companies House XML gateway and in need of some help here. I have got the example request code but need to send it via Adobe Dreamweaver. How do I do this. Do I have to insert some additional code at the bottom of this code, and also how do I send it? PLEASE HELP!

Code request so far;

<?xml version=“1.0” encoding=“utf-8”?>

<GovTalkMessage xsi:schemaLocation=“” xmlns=“” xmlns:dsig=“” xmlns:gt=“” xmlns:xsi=“”>

<Header> -
<MessageDetails> <Class>CompanyDetails</Class>

<SenderDetails> -

<Keys />


<CompanyDetailsRequest xmlns:xsi=“” xsi:noNamespaceSchemaLocation=“”>
<CompanyName>Bridger Limited</CompanyNumber>

Thanks if you can help.
