How to write xpath for xml with two namespaces?

How to write xpath for xml with two namespaces? - c#

I am trying to get the values of the title and link with the attribute equals to alternate. But with the namespaces, I find it a bit challenging to get the values.
I have added my namespaces as follows but my result is comming back with Enumeration yeilds no result:
nameSpaceManager_ = new XmlNamespaceManager(new NameTable());
nameSpaceManager_.AddNamespace("viz", "http://www.vizrt.com/atom");
nameSpaceManager_.AddNamespace("atom", "http://www.w3.org/2005/Atom");
I am using XDocument with a mixture of linq and xpath to query my data.
I use the XPath as follows:
var showName = showNode.XPathEvaluate("/atom:entry/atom:title/text()", nameSpaceManager_);
UPDATE

Updated Query:
var exEl = xmlDoc.XPathSelectElements("//atom:feed/atom:entry[atom:category/#term='show']", nameSpaceManager_);
foreach (var showNode in exEl.Cast<XElement>())
{
var showName = showNode.XPathSelectElement("/atom:entry/atom:title", nameSpaceManager_).Value;
var linkTypes = showNode.XPathSelectElements("/atom:entry/atom:link[#rel='alternate']", nameSpaceManager_)
.Select(e => e.Attribute("type").Value);
}

You do almost everything right.
Just use XPathSelectElement instead of XPathEvaluate.
var showName = showNode.XPathSelectElement("/atom:entry/atom:title", nameSpaceManager_).Value;
var linkTypes = showNode.XPathSelectElements("/atom:entry/atom:link[#rel='alternate']", nameSpaceManager_)
.Select(e => e.Attribute("type").Value);

Sum same named xml nodes

I have edited this little MSDN example https://support.microsoft.com/en-us/kb/311530
And I have the following 2 XML's
Book1.xml
<?xml version="1.0"?>
<catalog>
<book1 id="1" />
<bookSum number="1" />
</catalog>
Book2.xml
<?xml version="1.0"?>
<catalog>
<book2 id="2" />
<bookSum number="1" specialAttribute="123" />
</catalog>
C# Code
XmlReader xmlreader1 = XmlReader.Create(#"C:\Book1.xml");
XmlReader xmlreader2 = XmlReader.Create(#"C:\book2.xml");
DataSet ds = new DataSet();
ds.ReadXml(xmlreader1);
DataSet ds2 = new DataSet();
ds2.ReadXml(xmlreader2);
ds.Merge(ds2);
ds.WriteXml(#"C:\Merge.xml");
Console.WriteLine("Completed merging XML documents");
Merge.xml (Book1.xml + Book2.xml)
<?xml version="1.0" standalone="yes"?>
<catalog>
<book1 id="1" />
<bookSum number="1" />
<bookSum number="1" specialAttribute="x" />
<book2 id="2" />
</catalog>
And the question is
how to join
<bookSum number="1" />
<bookSum number="1" specialAttribute="123" />
into one line ?
<bookSum number="2" specialAttribute="123" />

I did it this way and is working:
var doc = XDocument.Load(#"C:\Book1.xml");
doc.Root.Add(XDocument.Load(#"C:\Book2.xml").Root.Elements()); // merged
var sum = doc.Descendants("bookSum").Attributes("number").Sum(t => int.Parse(t.Value));
var xElement = new XElement("bookSum", new XAttribute("number", sum));
foreach(var attrib in doc.Descendants("bookSum").Attributes())
{
if (xElement.Attribute(attrib.Name) == null)
xElement.Add(attrib);
}
doc.Descendants("bookSum").ToList().ForEach(t => t.ReplaceWith(xElement));
doc.Root.Descendants("bookSum").First().Remove();
Console.WriteLine(doc);

I have written the code with some help so as to parse the Xml and get the data as
var reader = new StreamReader(#"C:/Users/Administrator/Downloads/direct.xml")
var xmlDoc = XDocument.Load(reader);
XNamespace atom = "http://www.w3.org/2005/Atom";
XNamespace metadata = "http://schemas.giooglt.com/ado/2007/08/dataservices/metadata";
XNamespace dataservices = "http://schemas.google.com/ado/2007/08/dataservices";
var result = xmlDoc.Root.Elements(atom + "entry")
.Select(e => new {
Title = e.Element(atom + "title").Value,
Id = e.Element(atom + "id").Value,
Urls = e.Elements(atom + "link")
.Where(l => l.Element(metadata + "inline") != null)
.SelectMany(l => l.Element(metadata + "inline")
.Element(atom + "feed")
.Elements(atom + "entry")
.Select(e1 => e1.Element(atom + "content")
.Element(metadata + "properties")
.Element(dataservices + "Url").Value))
});
foreach (var item in result)
{
Debug.WriteLine("{0}, {1}, {2}", item.Title, item.Id,item.Urls);
Debug.WriteLine(item.Urls.GetType());
foreach(var i in item.Urls){
Debug.WriteLine("i :"+i);
}
}
My desired output is -
M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),http://googlgt.com/en-US/PartnerDetails.aspx? PartnerId=42555&wt.mc_id=66ttet
M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),http://pinpoint.microsoft.com/en-US/RFI.aspx?partnerId=4295719419&wt.mc_id=54545
vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),http://googlgt.com/en-US/PartnerDetails.aspx?PartnerId=42555&wt.mc_id=66ttet
vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),http: //pinpoint.microsoft.com/en-US/RFI.aspx?partnerId=4295719419&wt.m
But the output I am getting from the above piece of code is :
M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]
M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]
vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]
vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]
I am getting the output as specified above and I am not quite sure why am I getting the above output. I desire to get the result for each 'Url' as is specified in the desired output. been fighting for a while to get the desired result.
Any help is appreciated. Novice programmer, new to C# not sure how to get the output. Is this because of the wrong XML format?

Your code is trying to call ToString() on a Linq expression which is why you're seeing that System.Linq.Enumerable+ gobbledygook.
You need to enumerate the Urls:
foreach (var item in result)
{
var i = 0;
foreach (var url in item.Urls)
{
Debug.WriteLine("{0}, {1}, {2}", item.Title, item.Id, url);
Debug.WriteLine(url.GetType());
Debug.WriteLine("i : " + i++);
}
}
or a more succinct way to write this:
result.ToList().ForEach(item =>
{
var i = 0;
foreach (var url in item.Urls)
{
Debug.WriteLine("{0}, {1}, {2}", item.Title, item.Id, url);
Debug.WriteLine(url.GetType());
Debug.WriteLine("i : " + i++);
}
});

How to Get the Id variable from the XML in c#?

I want to parse the id field to receive the Id information which is under

4294
which is here
<d:Id>4294</d:Id>
But I am getting the output as
<d:Id xmlns:d="http://schemas.microsoft.com/ado/2007/08/dataservices">4294</d:Id>
Do not understand why am I getting that particular information and not just the 'Id' value
Thanks for help in advance.

Use entry.Identity.Value instead of entry.Identity:
String uniqueId = BusinessNeedNumber + IndustryFocusNumber + Competency + sta + ci + coun+entry.Identity.Value;

SelectNodes give the empty node even if the xml Contains the node

XPathNavigator nav = xmlDoc.CreateNavigator();
XmlNamespaceManager nsMgr = new XmlNamespaceManager(nav.NameTable);
nsMgr.AddNamespace(string.Empty,#"http://www.w3.org/2005/Atom");

nsMgr.AddNamespace("openSearch",#"http://a9.com/-/spec/opensearch/1.1/");
XmlNodeList nodeList = xmlDoc.SelectNodes("entry",nsMgr); // nodeList is empty why?
After execution of above code nodeList is empty
But when I see the XMLDocument it contains the the required Nodes entry

There's a known issue in .NET with the default XML namespace - contrary to what is defined in the XML standards, in .NET you cannot use a string.Empty as the prefix - you need to use something else.
Try this:
XPathNavigator nav = xmlDoc.CreateNavigator();
XmlNamespaceManager nsMgr = new XmlNamespaceManager(nav.NameTable);
nsMgr.AddNamespace("def", #"http://www.w3.org/2005/Atom"); <== Give this a prefix!
nsMgr.AddNamespace("dxp", #"http://schemas.google.com/analytics/2009");
nsMgr.AddNamespace("openSearch", #"http://a9.com/-/spec/opensearch/1.1/");
XmlNodeList nodeList = xmlDoc.SelectNodes("/def:feed/def:entry", nsMgr);
Now, this list does have two nodes in it - right?

Parsing XML Element

i am trying to parse an xml element (DItem >> Title)
below is my code but somehow i am not getting hold of it.... any help?
XDocument xdoc1 = XDocument.Load(url);
XNamespace ns = "http://sitename/items.xsd";
string topic = xdoc1.Descendants(ns + "DItem")
.Select(x => (string)x.Attribute("Title"))
.FirstOrDefault();
<?xml version='1.0'?>
<root xmlns="http://www.w3.org/2005/Atom">
<title type="text">title</title>
<entry>
<id>da7d3189-fd89-4d3f-901c-30eab7a3baa5</id>
<title type="text">Swimming Pools</title>

<link rel="alternate" href="link" />
<link href="link" />
<content type="application/xml">
<Items xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.namespace.xsd">

<Item Id="28466" CatalogUrl="url">
<DItem xmlns:content="http://namespace.xsd" TargetUrl="http://index.html" Title="my title">
<content:Source Acronym="ABC" OrganizationName="ABC" />
</DItem>
</Item>
</Items>
</content>
</entry>
</root>

Using the namespace "http://www.namespace.xsd" should (and does) work:
XNamespace ns = "http://www.namespace.xsd";
string topic = xdoc1.Descendants(ns + "DItem")
.Select(x => (string)x.Attribute("Title"))
.FirstOrDefault();
Since DItem is not qualified with a namespace itself, it will use the default namespace specified asxmlns="http://www.namespace.xsd" on its parent element.
