I want to generate a xml code like below example:-
<?xml version="1.0" encoding="utf-8"?>
<Root xmlns ="abc.xyz.xsd" xmlns:xsi="http://namespace">
</Root>
My C# code is like below:
XNamespace xsi = "http://namespace";
XDocument doc = new XDocument(
new XDeclaration("1.0", "utf-8", null),
new XElement("Root",
new XAttribute("xmlns", "abc.xyz.xsd"),
new XAttribute(XNamespace.Xmlns + "xsi", xsi)
);
This code gives error while saving. What am I doing wrong?
You can use with single namespace
XNamespace xsi = "http://namespace";
XDocument doc1 = new XDocument(
new XDeclaration("1.0", "utf-8", null),
new XElement(xsi + "Root",
new XAttribute("xmlns", "abc.xyz.xsd"),
new XAttribute(XNamespace.Xmlns + "xsi", "http://namespace"),
new XElement(xsi + "Child",
new XElement(xsi + "DifferentChild", "other content")
)
));
See this for reference https://msdn.microsoft.com/en-us/library/bb387075.aspx
The output will look like this
<?xml version="1.0" encoding="utf-8"?>
<xsi:Root xmlns="abc.xyz.xsd" xmlns:xsi="http://namespace">
<xsi:Child>
<xsi:DifferentChild>other content</xsi:DifferentChild>
</xsi:Child>
</xsi:Root>
You should add your Root element with namespace (namespace + "Root") since you're using namespaces.
Like this:
XNamespace xsi = "http://namespace";
XNamespace ns = "abc.xyz.xsd";
XDocument doc = new XDocument(
new XDeclaration("1.0", "utf-8", null),
new XElement(ns + "Root",
new XAttribute("xmlns", ns),
new XAttribute(XNamespace.Xmlns + "xsi", xsi)));
See MSDN article concerning creation of documents having namespaces.

Question update: im very sorry if my question is not clear
here is the code im using right now
XDocument doc = XDocument.Parse(framedoc.ToString());
foreach (var node in doc.Descendants("document").ToList())
{
XNamespace ns = "xsi";
node.SetAttributeValue(ns + "schema", "");
node.Name = "alto";
}
and here is the output
<alto p1:schema="" xmlns:p1="xsi">
my goal is like this
xsi:schemaLocation=""
where does the p1 and xmlns:p1="xsi" came from?
When you write
XNamespace ns = "xsi";
That's creating an XNamespace with a URI of just "xsi". That's not what you want. You want a namespace alias of xsi... with the appropriate URI via an xmlns attribute. So you want:
XDocument doc = XDocument.Parse(framedoc.ToString());
foreach (var node in doc.Descendants("document").ToList())
{
XNamespace ns = "http://www.w3.org/2001/XMLSchema-instance";
node.SetAttributeValue(XNamespace.Xmnls + "xsi", ns.NamespaceName);
node.SetAttributeValue(ns + "schema", "");
node.Name = "alto";
}
Or better, just set the alias at the root element:
XDocument doc = XDocument.Parse(framedoc.ToString());
XNamespace ns = "http://www.w3.org/2001/XMLSchema-instance";
doc.Root.SetAttributeValue(XNamespace.Xmlns + "xsi", ns.NamespaceName);
foreach (var node in doc.Descendants("document").ToList())
{
node.SetAttributeValue(ns + "schema", "");
node.Name = "alto";
}
Sample creating a document:
using System;
using System.Xml.Linq;
public class Test
{
static void Main()
{
XNamespace ns = "http://www.w3.org/2001/XMLSchema-instance";
XDocument doc = new XDocument(
new XElement("root",
new XAttribute(XNamespace.Xmlns + "xsi", ns.NamespaceName),
new XElement("element1", new XAttribute(ns + "schema", "s1")),
new XElement("element2", new XAttribute(ns + "schema", "s2"))
)
);
Console.WriteLine(doc);
}
}
Output:
<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<element1 xsi:schema="s1" />
<element2 xsi:schema="s2" />
</root>
I am having trouble creating an XML document using LINQ.
The XML file I need to create has a root element of "ClinicalDocument".
The XML needs to be as follows
<?xml version="1.0" encoding="utf-8"?>
<ClinicalDocument xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="urn:hl7-org:v3"
xmlns:voc="urn:hl7-org:v3/voc"
xmlns:sdtc="urn:hl7-org:sdtc">
<!-- Rest of the document here. -->
</ClinicalDocument>
The code I have in trying to do this is
XNamespace xsi = "http://www.w3.org/2001/XMLSchema-instance";
XDeclaration dec = new XDeclaration("1.0", "UTF-8", null);
XDocument xDoc = new XDocument(dec,null);
XElement cDoc = new XElement("ClinicalDocumnet");
xDoc.Add(cDoc);
cDoc.Add(new XAttribute(XNamespace.Xmlns + "xsi", xsi.NamespaceName));
cDoc.Add(new XAttribute("xmlns","urn:hl7-org:v3"));
cDoc.Add(new XAttribute(XNamespace.Xmlns + "stdc","urn:hl7-org:sdtc"));
cDoc.Add(new XAttribute(XNamespace.Xmlns + "voc","urn:hl7-org:v3/voc"));
xDoc.Save("C:\\test\\test.xml");
I get an exception when trying to save the file.
{"The prefix '' cannot be redefined from '' to 'urn:hl7-org:v3' within the same start element tag."}
XNamespace ns = "urn:hl7-org:v3";
xDoc = new XDocument(dec, null);
cDoc = new XElement(ns + "ClinicalDocument");
xDoc.Add(cDoc);
cDoc.Add(new XAttribute(XNamespace.Xmlns + "xsi", "http://www.w3.org/2001/XMLSchema-instance"));
cDoc.Add(new XAttribute(XNamespace.Xmlns + "stdc","urn:hl7-org:sdtc"));
cDoc.Add(new XAttribute(XNamespace.Xmlns + "voc","urn:hl7-org:v3/voc"));
I need to generate xml like that:
<urlset xmlns:video="http://www.google.com/schemas/sitemap-video/1.1" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>http://blabla</loc>
<video:video>
<video:player allow_embed="yes">http://blablabla</video:player_loc>
</video:video>
</url>
I can't figure out the way to work with namespaces. I can't even create urlset element properly, I'm trying:
XNamespace _defaultNamespace = "http://www.sitemaps.org/schemas/sitemap/0.9";
XNamespace _videoNameSpace = "http://www.google.com/schemas/sitemap-video/1.1";
new XElement("urlset",new XAttribute(_defaultNamespace+"video",_defaultNamespace))
and it generates:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<urlset p1:video="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:p1="http://www.sitemaps.org/schemas/sitemap/0.9">
what's that p1 thing?
Namespace attributes are in xmlns namespace, so you should use
XNamespace.Xmlns+ attributeName for declaring namespaces:
XNamespace ns = "http://www.sitemaps.org/schemas/sitemap/0.9";
XNamespace video = "http://www.google.com/schemas/sitemap-video/1.1";
var urlset = new XElement(ns + "urlset",
new XAttribute(XNamespace.Xmlns + "video", video));
Produces
<urlset xmlns:video="http://www.google.com/schemas/sitemap-video/1.1"
xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" />
Complete xml generation will look like:
var urlset = new XElement(ns + "urlset",
new XAttribute(XNamespace.Xmlns + "video", video),
new XElement(ns + "url",
new XElement(ns + "loc", "http:/blabla"),
new XElement(video + "video",
new XElement(video + "player",
new XAttribute("allow_embed", "yes"),
"http:/blabla"))));
This question already has answers here:
XElement namespaces (How to?)
(2 answers)
Closed 10 years ago.
I currently have:
XNamespace xmlns = "XSDName";<br>
XNamespace xsi = #"http://www.w3.org/2001/XMLSchema-instance";<br>
XNamespace schemaloc = #"XSDName XSDName.xsd";
XDocument xdoc = new XDocument(
new XElement("BaseReport",
new XAttribute(xsi + "schemaLocation", schemaloc),
new XAttribute(XNamespace.Xmlns+"ns1", xmlns),
new XAttribute(XNamespace.Xmlns + "xsi", xsi));
This gives me:
BaseReport xsi:schemaLocation="XSDName XSDName .xsd" xmlns:ns1="XSDName" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
How can I have BaseReport read ns1:BaseReport?
The below code will give you the output that you want. The key is adding the defined namespace before the name and letting .NET figure out the correct prefix.
XNamespace xmlns = "XSDName";
XNamespace xsi = #"http://www.w3.org/2001/XMLSchema-instance";
XNamespace schemaloc = #"XSDName XSDName.xsd";
XDocument xdoc = new XDocument(
new XElement(xmlns + "BaseReport",
new XAttribute(xsi + "schemaLocation", schemaloc),
new XAttribute(XNamespace.Xmlns + "ns1", xmlns),
new XAttribute(XNamespace.Xmlns + "xsi", xsi)));
I need so generate XML like the following:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<url>
<loc>http://www.xyz.eu/</loc>
<lastmod>2010-01-20T10:56:47Z</lastmod>
<changefreq>daily</changefreq>
<priority>1</priority>
</url>
<url>
<loc>http://www.xyz.eu/2/</loc>
<lastmod>2009-10-13T10:20:03Z</lastmod>
<changefreq>daily</changefreq>
<priority>0.5</priority>
</url>
<url>
<loc>http://www.xyz.eu/3/</loc>
<lastmod>2009-10-13T10:19:09Z</lastmod>
<changefreq>daily</changefreq>
<priority>0.5</priority>
</url>
</urlset>
I cant seem to figure out how to add the namespace with no name without putting ' xmlns="" ' in all the url tags.
my code:
XNamespace blank = XNamespace.Get(#"http://www.sitemaps.org/schemas/sitemap/0.9");
XNamespace xsi = XNamespace.Get(#"http://www.w3.org/2001/XMLSchema-instance");
XDocument doc = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XElement(blank + "urlset",
//new XAttribute(XNamespace.Xmlns +"", blank),
new XAttribute(XNamespace.Xmlns + "xsi", xsi),
// This private method loops through the dictionary and creates all the page nodes
GetSiteMapChildren(pageIdVersionDic, site.Url)
));
Any ideas? Thanks
You need to declare the "blank" namespace as the default namespace. For example this works just fine:
XNamespace blank = XNamespace.Get(#"http://www.sitemaps.org/schemas/sitemap/0.9");
XNamespace xsi = XNamespace.Get(#"http://www.w3.org/2001/XMLSchema-instance");
XDocument doc = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XElement(blank + "urlset",
new XAttribute("xmlns", blank.NamespaceName),
new XAttribute(XNamespace.Xmlns + "xsi", xsi.NamespaceName),
new XElement(blank + "url",
new XElement(blank + "loc", "http://www.xyz.eu/"),
new XElement(blank + "lastmod", "2010-01-20T10:56:47Z"),
new XElement(blank + "changefreq", "daily"),
new XElement(blank + "priority", "1"))
));
Console.WriteLine(doc.ToString());
