Check if XML Element exists

Question

How can someone validate that a specific element exists in an XML file? Say I have an ever changing XML file and I need to verify every element exists before reading/parsing it.

Accepted Answer

```
if(doc.SelectSingleNode("//mynode")==null)....
```

Should do it (where doc is your XmlDocument object, obviously)

Alternatively you could use an XSD and validate against that
