findInjectedElementAt

public PsiElement findInjectedElementAt(PsiFile hostFile,
                                        int hostDocumentOffset)

Description copied from class: InjectedLanguageManager

Finds PSI element in injected fragment (if any) at the given offset in the host file.

E.g. if you injected XML "<xxx/>" into Java string literal "String s = "<xxx/>";" and the caret is at "xxx" then this method will return XmlToken(XML_TAG_START) with the text "xxx".
Invocation of this method on uncommitted hostFile can lead to unexpected results, including throwing an exception!
