For healing:
The Bloodied value does not seem to be in the XML -- you just need to do the math.
The Surges per Day value was already mentioned above.
The Healing Surge Value stat is only the *bonus* to the characters surge value (you have to add 1/4 HP to it to get the actual surge value). If you do not have a bonus to your surge value (many characters won't), the Healing Surge Value stat will not be in the file.
Code:
<Stat value="3">
<alias name="Healing Surge Value" />
<statadd type="item" value="3" charelem="d819a58" />
</Stat>
Most of what is needed to render the character sheet is in there. For example:
* Calculated stats like ability scores, defenses, init, healing, speed, armor penalty, skills, level, resistances, XP (and a breakdown is available for most things)
* Race, class, role, vision
* URL to the portrait
* Conditional bonuses to defenses/saves
* Inventory and quantity (with slot info)
* Brief text descriptions for feats and class abilities
* Powers chosen with action type, keywords, level, target info, and Hit: line
* Rituals available
Stuff that's missing:
* No calculated values for attack rolls or damage rolls
* No magic item descriptions
* No Miss, Effect, or Secondary attack information for powers
