If your xml documents are small (fit into memory), then the best is to use XMLDOMParser to build you a dom tree. Then you can do all kind of queries depending on the structure. The following example assumes a flat structure and non-repeating child nodes: doc := '<yourxmldocument/>' dom := XMLDOMParser parseDocumentFrom: doc readStream. objects := Array streamContents: [ :stream | dom tagsNamed: #product do: [ :tag | | object | object := Dictionary new. tag elementsDo: [ :element | object at: element name put: element contentString ]. stream nextPut: object ] ]. (Btw the idea that XMLElement >> #tag is returning a symbol and the #tags*[dD]o: methods are expecting a symbol for tag is a very bad idea. It degrades performance.) And where did the XML-Parser go from Pharo?

How big is your XML file? Molecular biology?

I know that there is OPAX to better handle XML files to support an either conversion using a bit of reflection but I did not use it myself.
