I need to loop through every <w> of the document
First need to find out it’s child <w Pr> has child <wStyle> that contain w:val and get its value and <w:t>Trees, shrubs, lianas or herbaceous vines</w:t>
Then look at <w>’s other <w:r> children and find out if it’s any of child has
<w:rStyle w:val="name"/> and get it’s value and <w:t>SAPINDACEAE</w:t> value

So the result in key value dictionary

Style=” Description” : Text = “ Description”
Style = “Habit” : Text= ” Trees, shrubs, lianas or herbaceous vines”
Style= “Family” : Text = “SAPINDACEAE”

I’m using openxml document xdoument I need to find it's every style and their content from every <w>
And their text value
If some you know better way then please help me
