XQuery(或XPath)是否具有更新、插入和删除以及选择的等价物?

I know how to find what I need from XML using XPath. The syntax takes a little getting used to, but it is quite powerful. I'm interested in learning XQuery also, but the SQL like syntax seems awkward. Even so, if it can provide not just a select equivalent, but also update, insert, and delete as SQL does, I will forgive all awkwardness.I know how to find what I need from XML using X
