Infopath form to HTML using csharp -- 金大昊（jindahao）

I know converting Infopath form to HTML is pain task. Recently i have worked on one assignment where i need to send infopath form as email. So sending browser based infopath as email content is not possible so i decided to convert Infopath form to HTML and attach to email message. I have tried many method to convert infopath to html but all are ended with pain. At the end i found good solution so we can convert infopath form to html. I would like to share this approach because i’m sure you won’t get good solution by searching internet. Best method is using .net programming and using XSLT transform approach we can convert infopath form to HTML content. You can find the below steps to html conversion.

Creating the XSL file form infopath form 

1. Open infopath form using Infopath form designer.
2. Go to File -> Click on ‘Save as Source files’ menu will ask for location.  Save the content
3. Goto saved location and you can find views.xsl file, It will be in XSLT format.
4. Copy the views.xsl file to sharepoint 12hive Layout folder.

Below c# method used to convert xsl file to HTML. 

public XslCompiledTransform getXSLTemplate(SPSite Site, string templateName)

{

XslCompiledTransform transform = new XslCompiledTransform();

try

{

//Reading the Template

WebClient client = new WebClient();

client.Credentials = CredentialCache.DefaultCredentials;

Stream stream = client.OpenRead(Site.RootWeb.Url + "/_layouts/" + templateName + ".xsl")

// load stylesheet into the transformer

using (XmlTextReader stylesheet = new XmlTextReader(stream))

{

   transform.Load(stylesheet);

}

stream.Close();

}

catch (Exception ex){throw ex} 

return transform;

}

Calling below method will return the html string

XslCompiledTransform transform = getXSLTemplate(page, templateName);

StringWriter sWriter = new StringWriter();

HtmlTextWriter writer = new HtmlTextWriter(sWriter);



// read the contents (XML) out of the InfoPath form

using (XmlReader reader = new XmlTextReader(spFile.OpenBinaryStream()))

{

XmlTextWriter results = new XmlTextWriter(writer.InnerWriter); 



// Perform the transformation

transform.Transform(reader, results);

reader.Close();

}
