Assign the output of an XQuery query to a variable in JavaScript

Hi, I'm facing an issue that involves using XQuery on XML data stored in a variable. Here is an example of the XML structure:

<channel>
<available>yes</available>
<label>CNN</label>
</channel>
<channel>
<available>yes</available>
<label>BBC</label>
</channel>
....

I need to retrieve values from this XML using conditions such as:

For Channels.Channel

where Channel/availability = yes

And Channels.Channel/Label = «CNN»

Return  EXIST(Channels.Channel/Id)

My query is: How can I run XQuery to obtain this ID value and save the result in a JavaScript variable for later use and integration with other systems? If XQuery isn't feasible, please suggest an alternate method to extract variables from this XML.

Thank you!

Answer №1

I find your example a bit perplexing, but if I understand it correctly, it seems like this code snippet will retrieve all the ID values.

for $channel in $channels/channel
where ($channel/available = 'yes' and $channels/channel/label = 'CNN')
return $channel/id

If you need to interact with other systems, consider creating a JSON webservice and passing the data back to your JavaScript.
