Today I got a question:

How many lines of code are there in our SharePoint solution?

After a little search, I found that PowerShell is really a nice tool to count lines of code:

• How do you count lines of code (stackoverflow)?

I wanted to count lines for different types of code:

1. Code Behind written in C#, the files have .cs file extension
2. JavaScript code (except jQuery, angular or knockout frameworks)
3. PowerShell files (.ps1 and psm1)
4. Xml files (all the SharePoint .xml files)

Here is the powershell code that counts lines of code:

Why should we need to serialize javascript objects as XML. I don’t know. It is of course more a server side need. And there actually a need for javascript serialization as xml in node.js. To serialize as json is very simple: JSON.stringify(myobjects). I was just curious if there was a tool for xml serialization in javascript. There is a nice javascript tool called XMLWriter, developed by Ariel Flesler. Consider you have articles and want to serialize them as xml, let’s create a function for serializing:

$.ajax is great, it hides much of the complexity. But sometimes we need to work with “raw” javascript :) So let’s look behind the scenes. The XMLHttpRequest (or just XHR) is used to open a connection to a server without a page reload. Internet Explorer calls it ActiveXObject and it differs in IE versions. Wikipedia article gives a good example how to create one constructor for all browsers:

if (typeof XMLHttpRequest == "undefined") XMLHttpRequest = function () {
  try {
    return new ActiveXObject("Msxml2.XMLHTTP.6.0");
  }
  catch (e) { }
  try {
    return new ActiveXObject("Msxml2.XMLHTTP.3.0");
  }
  catch (e) { }
  try {
    return new ActiveXObject("Microsoft.XMLHTTP");
  }
  catch (e) { }
  //Microsoft.XMLHTTP points to Msxml2.XMLHTTP and is redundant
  throw new Error("This browser does not support XMLHttpRequest.");
};

The remainder is more or less the same among the browsers. We open a connection defining the HTTP verb, URI and async mode (true or false):

Det finns ett exempel här.

//defaultAspx är sidan (SPListItem i Sidor)
//måste checkas ut först
//mgr är WebPartManager
//wp är contentEditorWebPart
web.AllowUnsafeUpdates = true;
XmlDocument xmlDoc = new XmlDocument();
XmlElement xmlElement = xmlDoc.CreateElement("Content");
xmlElement.InnerText = ((Microsoft.SharePoint.WebPartPages.ContentEditorWebPart)wp).Content.InnerText.ToString();
xmlElement.InnerText = xmlElement.InnerText.ToString().Replace("#HEADING#", "Welcome for welcome");
wp.Content = xmlElement;
mgr.SaveChanges(wp);
defaultAspx.File.CheckIn("");
defaultAspx.File.Publish("");
web.AllowUnsafeUpdates = false;
```Man måste skapa nytt XmlDocument och XmlElement, om man försöker skriva direkt till wp.Content.InnerText kommer det inte uppdateras. I det här fallet, byter vi ut #HEADING# mot något mer passande.

Ville spara min blogg som en dagbok för utskrift. Exporterade hela bloggen som xml. Inga problem. Sedan var det dock nästan omöjligt att enkelt skriva in det i Word / OpenOffice. Jag har skrivit en liten css-fil som formaterar det lite så att man kan skriva ut. Lägg till:

<?xml-stylesheet type = "text/css" href="wordpress.css"?>

direkt efter:

<?xml version="1.0" encoding="UTF-8" ?>

Lägg filen “wordpress.com” i samma mapp. Här är wordpress.css
