Then I would say that fixing a broken item would just require the normal xp for crafting it, +5000
Exactly right.
You can mend a broken magic weapon, suit of armor, or shield if it is one that you could make. Doing so costs half the XP, half the raw materials, and half the time it would take to craft that item in the first place.
You can also mend a broken wondrous item if it is one that you could make. Doing so costs half the XP, half the raw materials, and half the time it would take to craft that item in the first place.
You can also mend a broken ring if it is one that you could make. Doing so costs half the XP, half the raw materials, and half the time it would take to forge that ring in the first place.
Rings, weapons, armor, shields and wondrous items can all be repaired if "broken" for 1/2 XP cost and time.
There are three important terms here, "damaged" "destroyed, "and "broken."
"Damaged" (but still functional) magic items may be repaired with a simple "Mending" spell.
"Destroyed" may or may not mean "Broken." This may even be situational. Certainly a disintegrated into dust item is fully "destroyed" and not repairable at all.
On the other hand, a sundered weapon is "destroyed" per the Sunder description, but would appear to only be "smashed" by the breaking an object rules, though it would seem to be merely "broken" by the item creation rules.
I think these terms are not used precisely at all and it is simply a DM's call as to whether a magic item is broken beyond repair (as in the item creation rules) or not.
Using a wish to repair a broken magic item (weapon, armor, shield, ring or wondrous item) would require 1/2 the normal creation XP (then doubling that, which makes it the same as the normal creation XP) plus the 5,000 XP of the wish.
"When a wish creates or improves a magic item, you must pay twice the normal XP cost for crafting or improving the item, plus an additional 5,000 XP. "
