How to Use GridView to display XML Web Response By Attribute Name Instead of DataSet Column Name

Question

I'm trying to display an XML Web Response using the ASP.Net form GridView. I'm new to the .NET framework so I'm struggling with some of the particulars.

I'm developing a search engine so the XML response is the result of a search for a particular phrase or word. This is a sample of the XML response

<response>
<lst name="responseHeader">
<int name="status">0</int>
<int name="QTime">8</int>
<lst name="params">
<str name="qf">recordkey</str>
<str name="df">text</str>
<str name="echoParams">all</str>
<str name="indent">true</str>
<str name="wt">xml</str>
<str name="q">*:*</str>
</lst>
</lst>
<result name="response" numFound="281" start="0">
<doc>
<str name="Date Created">2014-10-30</str>
<str name="Facility">*****</str>
<str name="Author">*********</str>
<str name="Source System ID">*******</str>
<str name="Data Source">************</str>
<str name="Title">ENGINEERING INITIATION</str>
<long name="_version_">1504985395557826560</long>
</doc>
<doc>
<str name="Date Created">2011-09-30</str>
<str name="Facility">*********</str>
<str name="Author">************</str>
<str name="Source System ID">***</str>
<str name="Data Source">***************</str>
<str name="Title">USE OF REGISTERED....</str>
<long name="_version_">1504985395859816448</long>
</doc>
<doc>.....
  ...........

I blocked out some of the content but you get the idea.

Once I get the response I use a StreamReader to read the xml and put it into a XMLDocument.

  XmlDocument myXMLDocument = new XmlDocument();

            GridView1.DataSource = myXMLDocument; 

            StreamReader myXMLReader = new StreamReader(response.GetResponseStream());

            ds.ReadXml(myXMLReader);

            GridView1.DataSource = ds.Tables["str"];

            GridView1.DataBind();

After that I load it into a DataSet and bind the table "str" to the Gridview which produces this result

name	              str_Text	              lst_Id	doc_Id
qf                     recordkey                1	     
df                      text                    1	 
echoParams               all                    1	 
indent                  true                    1	 
wt                      xml                     1    	 
q                       *fire*                  1	 
Date Created          2014-10-30                          0
Facility                *****                             0
Author                  ****                              0
Source System ID        ***                               0
Data Source             ****                              0
Title                    ****                             0
Date Created         2011-09-30                           1
Facility                ****                              1
Author                  ****                              1
Source System ID        ****                              1
Data Source             *****                             1
Title               USE OF REGISTERED...                  1
Date Created        2011-11-03                            2
Facility                ****                              2
Author                 *****                              2
Source System ID        ***                               2
Data Source           *******                             2
Title                REQUEST...                           2

Now, the problem, I'm having problems organizing the content in the gridview. It only recognizes the column names as field names. I want to be able to to organize the information into a more typical search format such as

Date Created - "Followed by the title here"

Author Name

But I can't manipulate those things because they aren't seen as fields. So my overarching question. How do I use the gridview so I can manipulate based on attributes instead of the column names in the dataset? Do I have to bind it to the grid differently? Is there a sort that needs to be coded (Like by doc ID)? I don't really care the method I just need to be able to do it.

You can use the following linq to extract data from the dataset

            var results = ds.Tables["str"].AsEnumerable()
                .Where(x => x.Field<string>("name") == "qf")
                .Select(y => y.Field<string>("str_Text"));

I don't think the code above will be the best solution. I think parsing line by line like a text document will give better results. Try using a treeview like the code below : Recursive adding XML into TreeView
