Replace functionality using XSLT

By


Introduction:
In my previous article I have explained about Read cookies value using C#.net Asp.Net. In this article I am going to explain the replace functionality using xslt.

Explanation:
I need to replace space with – symbol in my input. So I wrote a below template to do this operation.
<xsl:template name="string-replace-all">
  <xsl:param name="text" />
  <xsl:param name="replace" />
  <xsl:param name="by" />
  <xsl:choose>
    <xsl:when test="contains($text, $replace)">
      <xsl:value-of select="substring-before($text,$replace)" />
      <xsl:value-of select="$by" />
      <xsl:call-template name="string-replace-all">
        <xsl:with-param name="text"
        select="substring-after($text,$replace)" />
        <xsl:with-param name="replace" select="$replace" />
        <xsl:with-param name="by" select="$by" />
      </xsl:call-template>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="$text" />
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>

Now I have called the function like below mentioned.
<xsl:variable name="myVar">
  <xsl:call-template name="string-replace">
    <xsl:with-param name="text" select="'This is a sample text with space'" />
    <xsl:with-param name="replace" select="' '" />
    <xsl:with-param name="by" select="'-'" />
  </xsl:call-template>
</xsl:variable>

Now if we print the value of  myVar then it will be This-is-a-sample-text-with-space

But if you like to replace only one character then you can use translate the method instead of the above method. Below is the sample code.



<xsl:value-of select="translate(Productservicename,' ','')"/>


Please note that method translate will replace only one character.

C# Extension Methods Example

By
In this article i am going to explain about Extension Methods  with example. Extension methods enable you to "add" methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type. If you do implement extension methods for a given type, remember the following points: An extension method will never be called if it has the same signature as a method defined in the type. Extension methods are brought into scope at the namespace level. For example, if you have multiple static classes that contain extension methods in a single namespace named Extensions, they will all be brought into scope by the using Extensions; directive. ...

CHECK IF FUNCTION EXISTS EXAMPLE

By
http://css-tricks.com/snippets/javascript/check-if-function-exists-before-calling/ When using scripts that are shared between different areas of a site, there may be cases where a function is called that doesn't exist. It makes sense on one page (the dependency is there) but not another. The difference is too slight to warrant forking the file into different versions. Instead, you can just check if the function exists before calling it to avoid the error: if ( typeof yourFunctionName == 'function' ) { yourFunctionName ( ) ; } jQuery code snippet to check whether a function exists within the JavaScript code. This can be easily achieved by using the jQuery.isFunction() function. Useful for checking if a jQuery function exists before calling it! < script type = "text/javascript" >      function  somenoobfunction ( )   {      }         // using jQuery      if   ( $. isFunction ( wi...
