XML Data multiple nodes - sql-server

Question

I have this xml file that all the rest of the nodes depends on the first one. I created a tree diagram to help illustrate it.
The problem I am having is that each node depends on the first one but they do not have any columns that link each other.
Here is the Link to the
XML Document
Here is my sql so far
SELECT
B.RD.query('racedata/todays_cls').value('.','varchar(max)') AS todays_cls,
B.RD.query('racedata/horsedata/horse_name').value('.', 'varchar(max)') AS horse_name,
B.RD.query('racedata/horsedata/jockey/jock_disp').value('.', 'varchar(max)') AS jockeyname
FROM #xmlData.nodes('data') AS B(RD)

Answer 1

Do the second CROSS APPLY on the result of the first one, so that you get <horsedata> elements that corresponds to current <racedata>. See a working demo example below.
sample data :
declare #xml XML = '
<data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.trackmaster.com/xmlSchema/ppXMLData.xsd">
<racedata>
<race>1</race>
<todays_cls>59</todays_cls>
<distance>800.0</distance>
<country>USA</country>
<horsedata>
<horse_name>BROADWAY KATE</horse_name>
<owner_name>C. Steve Larue</owner_name>
<program>1</program>
<pp>1</pp>
<weight>121</weight>
</horsedata>
<horsedata>
<horse_name>UNFAITHFUL</horse_name>
<owner_name>Melson, James L., Thomson, Ramona and Connell</owner_name>
<program>2</program>
<pp>2</pp>
<weight>121</weight>
</horsedata>
</racedata>
<racedata>
<race>2</race>
<todays_cls>87</todays_cls>
<distance>800.0</distance>
<country>USA</country>
<horsedata>
<horse_name>MAGNETIC START</horse_name>
<owner_name>Vernon D. Coyle</owner_name>
<program>1</program>
<pp>1</pp>
<weight>121</weight>
</horsedata>
<horsedata>
<horse_name>SKI POLE</horse_name>
<owner_name>Downunder Cable, LLC</owner_name>
<program>2</program>
<pp>2</pp>
<weight>121</weight>
</horsedata>
</racedata>
</data>
'
query :
SELECT
rd.value('race[1]', 'int') AS race,
rd.value('todays_cls[1]','int') AS todays_cls,
hd.value('pp[1]','int') AS pp,
hd.value('weight[1]','int') AS weight
FROM #xml.nodes('data/racedata') AS B(RD)
CROSS APPLY RD.nodes('horsedata') AS C(HD)
output :
UPDATE
In response to the updated query, you should've shredded on horsedata element level as suggested in the above query, something like this :
SELECT
B.RD.query('todays_cls').value('.','varchar(max)') AS todays_cls,
C.HD.query('horse_name').value('.', 'varchar(max)') AS horse_name,
C.HD.query('jockey/jock_disp').value('.', 'varchar(max)') AS jockeyname
FROM #xml.nodes('data/racedata') AS B(RD)
CROSS APPLY RD.nodes('horsedata') AS C(HD)
