Question

Greetings!

I’m working on wrapping my head around LINQ. If I had some XML such as this loaded into an XDocument object:

<Root>     <GroupA>         <Item attrib1='aaa' attrib2='000' attrib3='true' />     </GroupA>     <GroupB>         <Item attrib1='bbb' attrib2='111' attrib3='true' />         <Item attrib1='ccc' attrib2='222' attrib3='false' />         <Item attrib1='ddd' attrib2='333' attrib3='true' />     </GroupB>     <GroupC>         <Item attrib1='eee' attrib2='444' attrib3='true' />         <Item attrib1='fff' attrib2='555' attrib3='true' />     </GroupC> </Root> 

I’d like to get the attribute values of all of the Item child elements of a Group element. Here’s what my query looks like:

var results = from thegroup in l_theDoc.Elements('Root').Elements(groupName)               select new               {                   attrib1_val = thegroup.Element('Item').Attribute('attrib1').Value,                        attrib2_val = thegroup.Element('Item').Attribute('attrib2').Value,               }; 

The query works, but if for example the groupName variable contains ‘GroupB’, only one result (the first Item element) is returned instead of three. Am I missing something?

XElement e = XElement.Parse(testStr);  string groupName = 'GroupB'; var items = from g in e.Elements(groupName)             from i in g.Elements('Item')             select new {                            attr1 = (string)i.Attribute('attrib1'),                            attr2 = (string)i.Attribute('attrib2')                        };  foreach (var item in items) {     Console.WriteLine(item.attr1 + ':' + item.attr2); }
