xml nodes() in tsql - 匹配父节点和子节点属性

Question

I am trying to query following xml structure:

<effect><![CDATA[<p>some text</p>]]>
  <product code="4298271" />
  <product code="4298273" />
  <product code="4298274" />
  <product code="4298275" />
  <product code="4298276" />
</effect>
<effect><![CDATA[<p>some other text</p>]]>
  <product code="5298271" />
  <product code="5298273" />
  <product code="5298274" />
  <product code="5298275" />
  <product code="5298276" />
</effect>

I need to transform this data to a table like below:

Effect   ProductCode

some text       4298271
some text       4298273
some text       4298274
...
...

Is it even possible? I can get the list of product rows which are under every effect parent but no idea how to match it with the effect header from which the text should be queried.

Let's say that effect is root node for simplifying.

Even though the XML isn't really a valid document - you can still query it in T-SQL using XQuery - something like this:

DECLARE @input XML = '<effect><![CDATA[<p>some text</p>]]>
  <product code="4298271" />
  <product code="4298273" />
  <product code="4298274" />
  <product code="4298275" />
  <product code="4298276" />
</effect>
<effect><![CDATA[<p>some other text</p>]]>
  <product code="5298271" />
  <product code="5298273" />
  <product code="5298274" />
  <product code="5298275" />
  <product code="5298276" />
</effect>'

SELECT
    xc.value('(../text())[1]', 'varchar(50)'),
    xc.value('(@code)[1]', 'int')
FROM
    @input.nodes('/effect/product') AS XT(XC)

This produces an output:
