I have added HTML2XHTML as a nuget package to my project.
However I get "command not found" exception when I try to use
using Corsis.Xhtml;
//input is an html string
var xhtml = Html2Xhtml.RunAsFilter(stdin => stdin.Write(input)).ReadToEnd();
Can anyone please help me to fix this.
I know it's not on the subject but this is related and may solve your problem.
Try this please :
install SgmlReader from nuget
in case you have a string variable like below you will have to convert it into a TextReader object.
Now we are going to use the package installed.
static XmlDocument HTMLTEST()
{
string html = "<table frame=all><tgroup></tgroup></table>";
TextReader reader = new StringReader(html);
Sgml.SgmlReader sgmlReader = new Sgml.SgmlReader();
sgmlReader.DocType = "HTML";
sgmlReader.WhitespaceHandling = System.Xml.WhitespaceHandling.All;
sgmlReader.InputStream = reader;
XmlDocument doc = new XmlDocument();
doc.PreserveWhitespace = true; //false if you dont want whitespace
doc.XmlResolver = null;
doc.Load(sgmlReader);
return doc;
}
Input is string html format, and the return will be doc XmlDocument format. Your frame=all from html will become frame="all".
I can do whatever you like with the proper formatted XmlDocument doc, make it Xhtml if that's whant you wanted.

I'd like to set up a "mailer/newsletter" using MailKit. My site stack is based off of Blazor web assembly and uses .Razor components.
I'm wondering if there is a way to consume a razor component I've written to output HTML into the MimeMessage object I'm using to generate my email body and what that architecture would look like / the best way to accomplish this?
Similar question (though not Blazor):
Can I use an ASP.Net MVC Razor view to generate an nicely formatted HTML Body as the input for an email sent from the server?
Late answer since I just saw this question: I wrote an alternative system called BlazorTemplater which uses .razor files instead of .cshtml since I had exactly this problem.
You can convert your templates to .razor format and then use BlazorTemplater to render to HTML:
var html = new ComponentRenderer<MyRazorClass>()
.Set(c => c.SomeParameter = someValue)
.Render();
It supports parameters, DI injection and nested components so you should find it useful! It's also much easier to set up and works in Razor Class Libraries too.
I am using Blazor with MailKit here: Google Email Viewer in Server Side Blazor
I use MarkupString to display the email content like this:
#using MimeKit
#using MessageReader
#strError
<div style="padding:2px; vertical-align:top">
<div><i>#MimeKitMessage.Date.ToString()</i></div>
<div><b>From:</b> #MimeKitMessage.From.ToString()</div>
<div><b>To:</b> #MimeKitMessage.To.ToString()</div>
<div><b>Subject:</b> #MimeKitMessage.Subject</div>
<br />
<div>#((MarkupString)#htmlEmail)</div>
</div>
#code {
[Parameter] public Message paramMessage { get; set; }
MimeMessage MimeKitMessage;
string strError = "";
string htmlEmail = "";
protected override void OnInitialized()
{
try
{
if (paramMessage != null)
{
string converted = paramMessage.Raw.Replace('-', '+');
converted = converted.Replace('_', '/');
byte[] decodedByte = Convert.FromBase64String(converted);
using (Stream stream = new MemoryStream(decodedByte))
{
// Convert to MimeKit from GMail
// Load a MimeMessage from a stream
MimeKitMessage = MimeMessage.Load(stream);
// Convert any embedded images
var visitor = new HtmlPreviewVisitor();
MimeKitMessage.Accept(visitor);
htmlEmail = visitor.HtmlBody;
//If the email has attachments we can get them here
//var attachments = visitor.Attachments;
}
}
}
catch (Exception ex)
{
strError = ex.Message;
}
}
}
Referencing this example of using "json:Array": Converting between JSON and XML
I have two questions:
Does the namespace have to be "json"? I.e. if ns2 matched back to
"xmlns:ns2='http://james.newtonking.com/projects/json'" would that work?
Can the namespace be omitted? Can I just put "Array='true'"?
I'm about to try to test by trial and error, but thought maybe somebody would know the answer, or someone in the future would like to know.
Not that it matters a whole lot, but my XML is being generated by BizTalk 2010 and I'm using a WCF CustomBehavior to call NewtonSoft as follows:
private static ConvertedJSON ConvertXMLToJSON(string xml)
{
// To convert an XML node contained in string xml into a JSON string
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
ConvertedJSON convertedJSON = new ConvertedJSON();
convertedJSON.JSONtext = JsonConvert.SerializeXmlNode(doc, Newtonsoft.Json.Formatting.None);
convertedJSON.rootElement = doc.DocumentElement.Name;
return convertedJSON;
}
Looks like the namespace has to be exactly what they provide:
string xmlToConvert2 = "<myRoot xmlns:json='http://james.newtonking.com/projects/json'><MyText json:Array='true'>This is the text here</MyText><Prices><SalesPrice>10.00</SalesPrice></Prices></myRoot>";
string strJSON2 = ConvertXMLToJSON(xmlToConvert2);
As with normal xml, the namespace prefix can be any value. The follow worked equally as well as the above.
string xmlToConvert3 = "<myRoot xmlns:abc='http://james.newtonking.com/projects/json'><MyText abc:Array='true'>This is the text here</MyText><Prices><SalesPrice>10.00</SalesPrice></Prices></myRoot>";
string strJSON3 = ConvertXMLToJSON(xmlToConvert3);
How to convert an object to JSON data in windows phone. In web application I have used following code
JavaScriptSerializer serializer = new JavaScriptSerializer();
string stringData = serializer.Serialize(object);
I want to get the same output as that of the above code in windows phone 7.
JavaScriptSerializer is not supported on Windows Phone. An alternative is to use JSON.NET (you can add it via NuGet).
The code will then look like this:
string stringData = JsonConvert.SerializeObject(object);
firrst you need to download Newtonsoft.Json dll for parse web serevice
Just follow bellow step
Step1: Add Service References by right click on add References.
Step2: Now put your web service link on Service References and press go button, And also add Namespace of service Reference
Step3: Now add using Newtonsoft.Json.Linq; name space in your .cs file
Step4: Now add bellow code in your cs file
WhatsupServices.WhatsUpServiceSoapClient ws = new WhatsupServices.WhatsUpServiceSoapClient();
ws.ContactUsJSONCompleted += ws_ContactUsJSONCompleted;
ws.ContactUsJSONAsync(txtContactUsName.Text, txtContactUsPhone.Text, txtContactUsEmail.Text, txtContactUsComment.Text);
step6: now genrate your resopnce method
void ws_ContactUsJSONCompleted(object sender, dynamic e)
{
if (e.Error != null)
{
MessageBox.Show(LogIn.NetworkBusyMsg, LogIn.MsgHdr, MessageBoxButton.OK);
busyIndicator.IsRunning = false;
}
else
{
busyIndicator.IsRunning = false;
string Result = e.Result;
JObject obj = JObject.Parse(Result);
string ResultCode = (string)obj["ResultCode"];
string ResponceMessage = (string)obj["ResponseMessage"];
if (ResultCode == "1")
{
MessageBox.Show("Thank you for your message. We'll get back to you soon.", LogIn.MsgHdr, MessageBoxButton.OK);
NavigationService.GoBack();
}
else
{
}
}
}
Hope it will help you.
If any query than comment here.I wll help you
I want to create a JSON file for use as part of a simple web prototyping exercise. LinqPAD is perfect for accessing the data from my DB in just the shape I need, however I cannot get it out as JSON very easily.
I don't really care what the schema is, because I can adapt my JavaScript to work with whatever is returned.
Is this possible?
A more fluent solution is to add the following methods to the "My Extensions" File in Linqpad:
public static String DumpJson<T>(this T obj)
{
return
obj
.ToJson()
.Dump();
}
public static String ToJson<T>(this T obj)
{
return
new System.Web.Script.Serialization.JavaScriptSerializer()
.Serialize(obj);
}
Then you can use them like this in any query you like:
Enumerable.Range(1, 10)
.Select(i =>
new
{
Index = i,
IndexTimesTen = i * 10,
})
.DumpJson();
I added "ToJson" separately so it can be used in with "Expessions".
This is not directly supported, and I have opened a feature request here. Vote for it if you would also find this useful.
A workaround for now is to do the following:
Set the language to C# Statement(s)
Add an assembly reference (press F4) to System.Web.Extensions.dll
In the same dialog, add a namespace import to System.Web.Script.Serialization
Use code like the following to dump out your query as JSON
new JavaScriptSerializer().Serialize(query).Dump();
There's a solution with Json.NET since it does indented formatting, and renders Json dates properly. Add Json.NET from NuGet, and refer to Newtonsoft.Json.dll to your “My Extensions” query and as well the following code :
public static object DumpJson(this object value, string description = null)
{
return GetJson(value).Dump(description);
}
private static object GetJson(object value)
{
object dump = value;
var strValue = value as string;
if (strValue != null)
{
var obj = JsonConvert.DeserializeObject(strValue);
dump = JsonConvert.SerializeObject(obj, Newtonsoft.Json.Formatting.Indented);
}
else
{
dump = JsonConvert.SerializeObject(value, Newtonsoft.Json.Formatting.Indented);
}
return dump;
}
Use .DumpJson() as .Dump() to render the result. It's possible to override more .DumpJson() with different signatures if necessary.
As of version 4.47, LINQPad has the ability to export JSON built in. Combined with the new lprun.exe utility, it can also satisfy your needs.

I have used a .xsd file to generate Java classes, and with an XML file, I need to unmarshall.
I am using this code :
JAXBContext objJAXBContext = JAXBContext.newInstance("my.test");
// create an Unmarshaller
Unmarshaller objUnmarshaller = objJAXBContext.createUnmarshaller();
FileInputStream fis = new FileInputStream("test.xml");
JAXBElement<Root> objMyRoot = (JAXBElement<Root>) objUnmarshaller.unmarshal(fis);
Root mRoot = objMyRoot.getValue();
and I am getting this error:
javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"Root"). Expected elements are (none)
I have seen many solutions but nothing works in my project.
What i can try to do?
Your xml root is missing the namespace (uri) attribute.
You better try this on the XMLRootElement ...
#XmlRootElement(name = "root", namespace="")
Try
StreamSource streamSource = new StreamSource("test.xml")
JAXBElement<Root> objMyRoot = (JAXBElement<Root>) objUnmarshaller.unmarshal(streamsource, Root.class);
