How to join different level of nodes with xml.linq into one dataset row? Need someone to check code.

Hello,
I'm studying Linq to xml, and have below project. Codes is more or less working fine until I choose different level of nodes. Below examples I hope will explain everything.
So, how to join different level of nodes as one table record.

XmlFile:
<books>
    <book ID="0" published="2014">
        <title>Linq2Xml</title>
        <author>
            <first-name>John</first-name>
            <last-name>Brown</last-name>
        </author>
        <publisher>Amazon</publisher>
        <price>50.00</price>
    </book>
</books>

Open in new window




Dim query = From st In statesXml...<author> _
                    Select New With { _
                        .ID = st.@ID,
                        .published = st.@published,
                        .Name = st.<FirstName>.Value _
                                    }
        DataGridView1.DataSource = query.ToList

Open in new window

Return only FirstName Value, like:
ID  published             FirstName
0   | 2014           | <emtpycolumn>






Dim query = From st In statesXml...<book> _
                    Select New With { _
                        .ID = st.@ID,
                        .published = st.@published,
                        .Name = st.<FirstName>.Value _
                                    }
        DataGridView1.DataSource = query.ToList

Open in new window

Return only FirstName Value, like:
ID                               published             FirstName
<emptycolumn> | <emtpycolumn> | John

Hi dejandejanovic;

The following code snippet should get you what you need. I am not very proficient using the axis operators to get around the document but I can not find axis operater to access the ancestor of a node so the following starts at the ancestor node, book.

Dim query = From st In statesXml...<book> _
             Select New With { _
                .ID = st.@ID, _
                .published = st.@published, _
                .Name = st.<author>.<first-name>.Value _
            }

Please be aware that capitalization in an Linq to XML document is required to access nodes and attributes even though it's not required in Visual Basic to access variables in code.

Fernando,
works perfect.  Thank you...

I was also try to compose similar as your solution <node>.<childnode>, but somehow I just could not understand, and confgure the syntax.

You may have had an issue with the spelling of the node name and the capitalization of the node name. For example in your post you used FirstName where in the XML document it was spelled as first-name, and was spelled in lower case characters.

Yes, I have put in knowledge naming, and casing.
Comparison is wrong as I was very quickly translating from my language to EN, etc... :-)
