Getting data from Package XML

Hello

I have 2 questions …

1. The code below (Thanks Yitzhak), returns a packages task and connection manager, how do I return the contents of Execute SQL tasks?
2. Can someone recommend a tutorial on querying XML documents in TSQL,  I thought when I submitted my original question, it would be a one-off, but now we’re using it, I’m getting more questions

DECLARE @xmlXML;

SELECT @xml= XmlDoc  

FROMOPENROWSET(BULKN'C:\ImportTest.dtsx',SINGLE_BLOB)AS Tab(XmlDoc);

-- Data Flow Tasks

;WITH XMLNAMESPACES('www.microsoft.com/SqlServer/Dts'as DTS), rs AS

(

      SELECT col.value('@refId','VARCHAR(1024)')as refId

            , col.value('@connectionManagerRefId','VARCHAR(1024)')as connectionManagerRefId

            , col.value('@connectionManagerID','VARCHAR(1024)')as connectionManagerID

            ,SUBSTRING(PARSENAME(REPLACE(col.value('@connectionManagerID','VARCHAR(1024)'),':','.'), 2), 2,LEN(PARSENAME(REPLACE(col.value('@connectionManagerID','VARCHAR(100)'),':','.'), 2))-2)AS pristineGUID

            --, TRIM('{}' FROM PARSENAME(REPLACE(col.value('@connectionManagerID', 'VARCHAR(100)'), ':', '.'), 2)) AS GUID-- SQL Server 2017 and later

      FROM @xml.nodes('(//pipeline/components/component/connections/connection)')as tab(col)

)

SELECT*FROM rs;

-- Data Flow Tasks

;WITH XMLNAMESPACES('www.microsoft.com/SqlServer/Dts'as DTS), rs AS

(

      SELECT col.value('@refId','VARCHAR(100)')as refId

            , col.value('@name','VARCHAR(1024)')as TaskName

            , col.value('@componentClassID','VARCHAR(1024)')as ExecutableType

            , col.value('(connections/connection/@connectionManagerRefId)[1]','VARCHAR(1024)')as connectionManagerRefId

            , col.value('../@*:SqlStatementSource[1]','VARCHAR(1024)')as SqlStatementSource

      FROM @xml.nodes('//pipeline/components/component')as tab(col)

)

SELECT*FROM rs;

Thanks in advande
