How to indent the first line of each paragraph in a bound TextBlock?

Hi guys,

How to indent the first line of each paragraph in a bound TextBlock?

Here is the .xml

<?xml version="1.0" encoding="UTF-8"?><dataroot xmlns:od="urn:schemas-microsoft-com:officedata" generated="2011-06-04T14:21:45"><Animal><ID>01</ID><Name>Goat</Name><Description>The domestic goat (Capra aegagrus hircus) is a subspecies of goat domesticated from the wild goat of southwest Asia and Eastern Europe.

The goat is a member of the family Bovidae and is closely related to the sheep as both are in the goat-antelope subfamily Caprinae. There are over 300 distinct breeds of goat.[1] Goats are one of the oldest domesticated species, and have been used for their milk, meat, hair, and skins over much of the world.[2] In 2011, there were more than 924 million live goats around the globe, according to the UN Food and Agriculture Organization.[3]

The aurochs is ancestral to both zebu and taurine cattle.[citation needed] Now, these have been reclassified as one species, Bos taurus, with three subspecies: Bos taurus primigenius, Bos taurus indicus, and Bos taurus taurus.[4][5]

Complicating the matter is the ability of cattle to interbreed with other closely related species.

Mature male chickens less than one year old are called cockerels. The term "rooster" originates in the United States,[1] and the term is widely used throughout North America, as well as Australia and New Zealand.[2] The older terms "cock" or "cockerel", the latter denoting a young cock, are used in the United Kingdom and Ireland.[3]</Description><Image>Images/Cock.png</Image></Animal><Animal><ID>04</ID><Name>Dog</Name><Description>The domestic dog (Canis lupus familiaris or Canis familiaris) is a domesticated canid which has been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes.[2]

Although initially thought to have originated as a manmade variant of an extant canid species (variously supposed as being the dhole,[3] golden jackal,[4] or gray wolf[5]),
