Append HTML to XOM element

Question

I need to prepend HTML to existed XOM element. HTML represented as a String.

Here are my actions

1. Parse String into XOM Document
2. Remove root element(X) from Document
3. Prepend X to desired target element (Y)

I get an exception

nu.xom.WellformednessException: Cannot remove the root element
    at nu.xom.Document.removeChild(Unknown Source)
    at nu.xom.Node.detach(Unknown Source)

---

X element HTML

<div>
  Some test text
</div>

Answer 1

Current XOM implementation does not allow to remove root node.

To achieve desired goal it is need to add fake root and then detach required node.

In a context of mentioned step set:

Replace step 2 with next

1. Add fake root element - document.setRootElement(new Element("div"))
2. Detach desired element - element.detach()
