Datafield includes parent node

Question

I am confused. I have a datagrid like always. The
dataprovider is my xmllistcollection, I have done this many times.
the datagridcolumn in question is <mx:DataGridColumn
dataField="Botanical_Name"/>
The data in the xml is:
<Botanical_Name>
<em>Dianthus</em> 'Bath's Pink'
</Botanical_Name>
And that's exactly what I get in the field -- including the
surrounding <Botanical_Name> tags. I want what's IN those
tags, as usual not the tags. I
cannot change the XML it is coming from a source, I must
deal with it as is.
What am I missing?

Answer 1

It's not so simple. Yes, that is a child node. The XML
document I am working with is actually an RSS feed. There is a lot
of information in there, a lot of it I do not need. My original
application was designed to be used with a more customized XML
feed, and it worked fine. The client changed it on me to this
insane RSS formatting.
I have temporarily pulled the tile list I was using (with a
custom renderer) in order to more easily debug this data. I am
currently working with the code below. Clicking an item in the grid
should populate the fields above it with the appropriate data
items. Where would I put a function to get the actual text? The
datagrid is less important than the text field above.
<mx:VBox>
<mx:HBox>
<mx:Image id="largeImage" />
<mx:VBox>
<mx:Text id="plantName"
text="{tl.selectedItem.Botanical_Name}"/>
<mx:Text id="plantPhonetic" />
<mx:TextArea id="plantDetails"
text="{tl.selectedItem.Description}" />
<mx:LinkButton id="plantLink" label="READ MORE"
click="goPlant(event)" />
</mx:VBox>
</mx:HBox>
<mx:DataGrid id="tl" dataProvider="{coll}">
<mx:columns>
<mx:DataGridColumn dataField="Botanical_Name"/>
<mx:DataGridColumn dataField="Description"/>
<mx:DataGridColumn
dataField="Phonetic_Transcription"/>
</mx:columns>
</mx:DataGrid>
</mx:VBox>
