If a child node has a child node, return value
Hi, I currently have a content node which has a child, which also has a child. What I'm trying to get my head around is how to get the value of the media picker from the last child. e.g.
```
Parent_node
 --> Child_node
       --> Child_node
                |... uploaded image
```
I need to get the image url from the child.

Just now I have
```
@foreach ( var item in tabItems)
{
do something
}
```
But I think I need to do something like
```
@foreach (var item in tabItems)
{
    If(item.Child.HasPropertyValue = "tabsImage")
    {
    output the image url
    }
}
```
is that doable?

To try and help explain, I need to get an image url from the Green node in this tab list. So, foreach item gets the blue node information, then I need to get the image and any other information from the green node.

Hey Owain,

if it's what I think it is...

foreach(var node in nodes) //the blue guys
{ 
    foreach (var subnode in node.children) //the green guys 
    { 
        if(subnode.PropertyHasValue("image") 
        { 
            do something with it 
        }
    }
}

Hi Dave, Thanks but the If (subnode) always returns null.

I think it's pretty close, if I debug and hover over subnode, I can see "Properties: Count = 6" If I expand this in debug, I can see [0], [1], [2]...

If I expand [3] then I can see the property value "image". I just can't seem to get there to pull out the info.

I tried if
```
If(subnode.Properties[i]...
```
But that doesn't work. I didn't expect this to be so troublesome!

Edit:

So, child.Properties gets me the count of 6, which is the number of items I have on the last tab, but I just need to now search those 6 items to find the PropertTypeAlias.
```
 if (child.Properties.PropertyHasValue("tabsImage"))
    {
        var test = "test";
    }
```
This code gives the error: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: ''System.Collections.Generic.Dictionary
