Join tables, between column and attribute in xml data

I'm trying to make a query where I select all orders on a table, where the reference order number is the same as one of the values in an xml data type column. Since I'm using this in a much larger scale query i need in this case a LEFT JOIN.

So let's say I have :

Table 1 :       id   |    reference_number
                 1         1001
                 2         37904
Table 2 :     Guid                                    |     XMLData        |    Messagge
           A1625F87-9F6F-45FC-B2EE-06CE0FF8EDA0                                    OK
         
This is my xml :
<MyOrders>
          <Order>  
            <FACI>600</FACI>
            <CUOR>Test Email</CUOR>
            <OREF>37904</OREF> // this is the number i need
            <Customer>
              <M3CUNO>US00860</M3CUNO>
            </Customer>
            <OrderLine>
              <ITNO>360007</ITNO>
              <ORQT>1</ORQT>
              <WHLO>60S</WHLO>
              <SAPR>50.0000</SAPR>
            </OrderLine>
          </Order>
</MyOrders>

Now I need to get the message field from table 2 and the id from table 1. The OREF in xml must be the same as reference_number in table1 This is what I tried but I can't get that value.

select dbo.Table2.Message, dbo.Table1.id
from dbo.Table1 soh 
left join dbo.Table2 aq
on aq.XMLData.nodes.value('/MyOrders/Order/OREF') = soh.reference_number

Ofcourse this gives me this error :

Remote function reference 'aq.XMLData.nodes.value' is not allowed, and the column name 'XMLData' could not be found or is ambiguous

Any help would be highly appreciated. Thank you in advance

You should always provide a minimal reproducible example.

Assuming that the reference_number column is INTEGER data type.

SQL

...
on aq.XMLData.value('(/MyOrders/Order/OREF/text())[1]', 'INT') = soh.reference_number
