XPath Help

[alien_attack]

I have the followign XML document format.

<Asset>
<App Name="Title" Value"Pigs" />
<App Name="Rating" Value"G" />
</Asset>

I'm trying to figure out how to display the Title's value but being
sorted by the Rating's value.

So far I have.

Displays title: Asset_Metadata/App_Data[@Name = 'Title']/@Value

I've tried many other variations to get this to work with no luck.

Any help would be greatly appreciated.

I am not sure what you are trying to do (are you using DataSets or some
other form of control that would display XML content based on XPath ex-
pressions?), but you cannot sort in XPath expressions, you have to use
some external means, and your expression does not work because you have
no "Asset_Metadata" element or "App_Data" element in your document, the
names have to match exactly what is in the document.

Yes, I'm using an XMLDataSource. In binding (Client side) I'm using
XPath("...").

I can retrieve the title by doing the following:

XPath("Asset_Metadata/App_Data[@Name = 'Title']/@Value")

However, I only want those titles that fit into another filter.
Namely being a filter that determines the Rating of the title.

So basically I want all the titles a that have the following node:

<App_Data Name="Rating" Value="G" />

Can you do this with XPath?

What is the relation between the two App_Data elements? If the next
sibling element should be the App_Data element with Name="Rating" and
Value="G" then you can do e.g.
XPath("Asset_Metadata/App_Data[@Name = 'Title and
following-sibling::*[1][self::AppData and @Name = 'Rating' and @Value =
'G']]/@Value")
