You will first need to get your report XML from the dbo.Catalog table but something like this should work:
-- !!TODO get your report XML from the dbo.Catalog table
DECLARE @ssrsXML TABLE ( yourXML XML )
INSERT INTO @ssrsXML
SELECT '<TablixCell>
<CellContents>
<Textbox Name="bippie_passed_qa_photostamps_orders_amount">
<CanGrow>true</CanGrow>
<KeepTogether>true</KeepTogether>
<Paragraphs>
<Paragraph>
<TextRuns>
<TextRun>
<Value>=Fields!bippie_passed_qa_photostamps_orders_amount.Value</Value>
<Style>
<FontSize>8pt</FontSize>
<Format>''$''#,0.00;(''$''#,0.00);''''</Format>
</Style>
</TextRun>
</TextRuns>
<Style>
<TextAlign>Right</TextAlign>
</Style>
</Paragraph>
</Paragraphs>
</Textbox>
</CellContents>
</TablixCell>'
SELECT t.*, c.c.value('@Name', 'VARCHAR(100)' ) nameProperty
FROM @ssrsXML t
CROSS APPLY yourXML.nodes('//TablixCell/CellContents/Textbox' ) c(c)
