Sam, did you start with the Eclipse IDE for Java EE Developers, or something else? (I see Eclipse IDE for Java Developers listed your comment.)
The crux of the problem (or, special feature, depending on how you look at it) is that you have started with a "product package". By (current) design, you can not update "lower" level things, without updating that product package ... that is, it all has to be consistent, top-down. The comment mentions the product package Eclipse IDE for Java Developers 1.2.2, which is a Galileo level. To update that to the Helios level (which is assumed to be desired, since you are using the helios repo), you'll have to first select and install Eclipse IDE for Java Developers 1.3.1 level (That will be Helios SR1 level). In nearly all cases, this should be successful ... let us know if not. After that, the Helios XML and other features from helios repo will be consistent with what you have installed, so should install just fine. Or ... you could just start with the latest Helios download, from http://www.eclipse.org/downloads/ If you get the Eclipse IDE for Java EE Developers, it will already have XML and those other features at the latest, Helios SR1 level. Or, you can get the Eclipse IDE for Java Developers and install the other pieces you desire. Good luck.
> ... you'll have to first > select and install Eclipse IDE for Java Developers 1.3.1 level (That will be > Helios SR1 level). I meant to mention, to "find" these "Eclipse IDE" product packages, you'll have to deselect "group by categories" and can then find them in the list of everything installable. Typing "Eclipse IDE" in the 'search' text field at the top of the dialog can help narrow down what's listed.
