I'm sure I'm not the only one who needed this. Ok so I've spent a considerable amount of time trying to work this out, and here it is

Example XML of my repeatable custom content

<items>

<item>

<data alias="bannerImage">1053</data>

<data alias="bannerTitle">My Title 1</data>

</item>

<item>

<data alias="bannerImage">1054</data>

<data alias="bannerTitle">My Title 2</data>

</item>

</items>

Razor script to see my repeatable custom content called homepageBanner
```
var xml = @Library.ToDynamicXml(@Model.GetPropertyValue("homepageBanner"));
@xml
```
Razor scripting to output bannerTitle
```
@using System
@using System.Xml.Linq;
@using System.Linq
@using System.Collections.Generic
@using umbraco.MacroEngines
@inherits umbraco.MacroEngines.DynamicNodeContext
@{
       var xml = Library.ToDynamicXml(@Model.GetPropertyValue("homepageBanner"));

    foreach(XElement item in xml.BaseElement.Elements("item")) {    
        foreach(XElement data in item.Elements("data"))
        {
             if (data.Attribute("alias").Value == "bannerTitle")
             {
              @data.Value
             }
        }   
            

    }       
}
```
Output:
```
My Title 1
```
```
My Title 2
```
It's not very elegant but it works :) To be honest it's far easier to do it xslt but I wanted to have everything in Razor.

Ok, I worked out a solution that works with v6.

    XmlDocument xmlDoc = new XmlDocument();

    xmlDoc.LoadXml(milestoneIds.Value.ToString());

    XmlNodeList nodes = xmlDoc.GetElementsByTagName("item");

and then:

foreach (XmlNode xNode in (from XmlNode dataNode in nodes select dataNode.SelectNodes("data") into n where n != null from XmlNode a in n select xNode).Where(inText => !String.IsNullOrEmpty(inText.InnerText)))
    {
        // code here
    }

Hi! Anyone have an idea how to do this in umbaco v6 using Razor view?

<html><div class"row"> <div class="span4 carshow"></div>
 <div class="span4 carshow"></div>
 <div class="span4 carshow"></div></div><div class="row"> <div class="span4 carshow"></div>
 <div class="span4 carshow"></div>
 <div class="span4 carshow"></div>
</div></html>

@Tims example should work with only small changes in both 4.0 and 6.0 MVC views.

Just add @using System.Linq.Xml to the top of the view.

Instead of

var xml =Library.ToDynamicXml(@Model.GetPropertyValue("homepageBanner"));

you can do

var doc = XDocument.Parse(Model.Content.GetPropertyValue("homepageBanner"));
// or
var doc = XDocument.Parse(CurrentPage.homepageBanner.ToString());

foreach(var item in doc.Elements("item") { ... }
