Question

I am using XML.Linq to search through an XML file.

    <Location id="1284" parentID="1333" level="4" writerID="0" creatorID="3" nodeType="1266" template="1272" sortOrder="0" createDate="2012-04-09T09:41:33" updateDate="2012-08-16T11:43:11" nodeName="Princeton Junction" urlName="princeton-junction" writerName="Web" creatorName="My Name" path="-1,1092,1258,1333,1284" isDoc="">

I am using the following code to get everything I need but I also need to get the attribute url of Location\imageCrop\crops\crop.

    var query = from c in xmldoc.Root.Descendants("Location")
                    select c.Attribute("id").ToString().Replace("\"", "").Replace("id=", "") + "\t"
                            + c.Element("locationName").Value + "\t"
                            + c.Element("streetAddress").Value + "\t"
                            + c.Element("streetAddress2").Value + "\t"
                            + c.Element("city").Value + "\t"
                            + c.Element("state").Value + "\t"
                            + c.Element("zipCode").Value + "\t"
                            + c.Element("country").Value + "\t"
                            + c.Element("locationPhoneNumber").Value + "\t"
                            + c.Element("locationFaxNumber").Value+ "\t"
                            + c.Attribute("urlName").ToString().Replace("\"", "").Replace("urlName=", "");

How do I add that subquery to this query?

Answer 1

You just need:

c.Element("imageCrop").Element("crops").Element("crop").Attribute("url").Value

Of course, if there are multiple crop attributes, that will only return the first one – is that okay for you?

(As an aside, I would personally transform to an anonymous type with all the values stored in separate properties, and then convert that to a tab-separated value as a next step; I think you’d find it would make debugging easier.)
