I need to identify the text value of the child node element.

**Purpose:**

I want to create Transform file for an XML file so i need to replace the parent node **Connection** by comparing the value of the child node **ClientKey**

**My XML File:**

```
<Connection>
     <ClientKey>Client1</ClientKey>
     <ConnectionString>Test</ConnectionString>
     <WorkingDocs>Test</WorkingDocs>
     <TemplateDocs>Test</TemplateDocs>
     <PatientDocs>Test</PatientDocs>
     <ClientName>Test</ClientName>
     <ClientTimeZone>Test</ClientTimeZone>
     <ClientTimeDiff>Test</ClientTimeDiff>
     <ExceptionLogPath>Test</ExceptionLogPath>
</Connection>

```

How i can idendify the text of the **ClientKey** node
