Infopath form to HTML using csharp

Using XSLT transform we can convert infopath form to HTML content.

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();
}

That’s it......
