Once content of xml file is retrieved, in order to view this xml content as Html a custom Html helper needs to be created. Custom Helper can be created in two ways RenderXml is an extension method which receives three parameters first parameter is the object of HtmlHelper class, second parameter is content of xml file and third parameter is path of xslt file and this helper returns a htmlString.
Static method only receives content of xml file and path of xslt file returning a htmlString. Firefox and Microsoft Internet Explorer are recommended browsers for websites using java applets.

Negative Vote. Save Favourite. ReadAllText Server. IO; using System. Web; using System. Mvc; using System. Xml; using System. Parse; xmlSettings. The stylesheet for this example is shown below. You will have noticed that I have a template section for every XML element. First, import the necessary namespaces. You can use the string strHtml that is returned in this method in anyway useful for your application. Ex: You can assign it to a label or process it further as needed.
The C code is not only up to date but it also works perfectly. Thanks you very much indeed. Title: Thanks for you article Name: bhupal Date: PM Comment: It is helped me not only this all the articles all very good and impressed the way of presentation of the articles Title: Useful Code Name: Lakshman Date: AM Comment: This is really useful for begineer. Very useful for XSL beginners. Title: Assemble Reference Name: Selvaraj Date: AM Comment: I am getting the below error "The type or namespace name 'MemoryStream' could not be found are you missing a using directive or an assembly reference?
Please advice. This method works perfectly. Although this is a fairly straightforward example of using external objects within XSLT style sheets, much more complicated functionality, such as querying databases or calling Web services, can be accomplished with XSLT external objects. NET applications and demonstrate the asp:Xml Web control. By now you should feel comfortable working with the different classes within the System. Xml assembly that can be used to perform XSL transformations.
Not only would such a class provide more productive programming, but it would also allow your ASP. NET applications to leverage all the benefits offered by following object-oriented programming techniques. The code in Listing 7. This code leverages well-known classes such as HashTable to accomplish the transformation. NET code, as Listing 7. As this book was going to press, I wrote a new article demonstrating how the techniques shown in Listing 7.
NET pages. The asp:Xml server control also allows DOM structures to be passed into it programmatically using the Document and Transform properties:. XSLT provides a cross-platform, language-independent solution that can used to transform XML documents into a variety of structures.
Introduction Simple Object Access Protocol is one of the neatest XML based technologies to be introduced as of late, yet many people are still trying to get a handle on all of the new terms and acronyms that SOAP has uncovered. This article is written to help you dig through the SOAP Using built-in features of IIS 5.
In this However, if you need your form submission data to be more portable, it can be Posted on 04 Dec The W3C provides the following statement about templates: A stylesheet contains a set of template rules. MapPath "listing7. Output ; writer. Indented; writer. Note XSLT version 1. Calls to xsl:apply-imports cause an imported template with lower precedence to be invoked instead of the source style sheet template with higher precedence.
This is similar to named styles in CSS. The template is identified by name. This element provides greater flexibility during transformations as new XSLT versions come out in the future. This can be useful when a style sheet generates another style sheet. Similar to using default in a switch statement. Local parameters are scoped to the template in which they are declared. Works in conjunction with the xsl:strip-space element. Works in conjunction with the xsl:preserve-space element.
Similar to using case in a switch or Select statement. The xsl:template element can have the attributes shown in Table 7. Although optional, if this attribute is not included, the name attribute shown next must be included.
This attribute is used by xsl:call- template. Although optional, if this attribute is not included, the match attribute shown next must be included. The mode is simply a name that can be used by the xsl:apply-templates element to hit a template that does a specific form of transformation. For example, if you need a node named chapter within an XML document to be processed differently, depending on its position within the document, you can create different templates that all match the chapter node.
To differentiate the templates from each other because they have the same match attribute value a mode can be applied to each one. A call can then be made to the specific template that needs to be processed by using the xsl:apply-templates element and then specifying the template that has the desired mode.
Using Variables and Parameters: The xsl:variable and xsl:param Elements As programmers, we all take for granted the capability to use variables and pass parameters to functions. Tip The previous example shows a shortcut that can be used to embed data directly into attributes that will be written out to the result tree. This function exists to help identify the current node when it is different from the context node. In previous examples you have seen that the context node can be represented by the.
Before using elements that you know may not be supported, a check can be made to see if the processor does indeed support the element in question. This function converts numbers to a string using a format pattern supplied in the second parameter.
Here are some examples of using this function: The following function call returns 5, : format-number ," , " The following function call returns Three different system properties must be supported by a compliant XSLT processor, including xsl:version , xsl:vendor , and xsl:vendor-url.
This class was discussed in Chapter 6. Because the XmlDocument class provides node-creation capabilities, it will not provide the fastest throughput in XSL transformations. However, in cases where a DOM structure must be edited first before being transformed, this class can be used. Using the XslTransform class involves instantiating it, loading the proper style sheet with the Load method, and then passing specific parameters to its Transform method.
This process will be detailed in the next few sections. Open, FileAccess. Write "XPathDocument successfully created! Close ; xmlReader. For example, it can be used to resolve resources identified in xsl:include elements.
If this property is not set, the XslTransform class will use the relative path of the supplied XSLT style sheet to resolve any included style sheets.
Chapter 5 showed an example of using the XmlUrlResolver class to access authenticated documents. Transform The Transform method is overloaded and can therefore accept a variety of parameters. NET applications is shown next check the. Load xslPath ; xslDoc.
Transform doc,null,Response. MapPath "Listing7. Load Server. MapPath "Listing 7. Transform doc,args,Response. NET application that does this task. Add "firstName" ; while reader. MapPath "xsltGolfer. AddParam "golferName","", this.
NET Panels in xsltGolfer. Write excp. Close ; sw. Some other benefits of using extension objects include: Methods on classes within other namespaces other than System namespaces can be called. Extension functions allow better encapsulation and reuse of classes.
Style sheets can be kept smaller and more maintainable. MapPath "xsltExtension. NET Panels this. Xml; 5: using System. XPath; 6: using System. Xsl; 7: using System. Collections; 8: using System.

NET xsltTransform. Add "golferName","Heedy" ; xsltObjects.
SOAP Soup. Used in conjunction with imported style sheets to override templates within the source style sheet. When xsl:apply-templates is used, the XSLT processor finds the appropriate template to apply, based on the type and context of each selected node. Creates an attribute node that is attached to an element that appears in the output structure.
Used when a commonly defined set of attributes will be applied to different elements in the style sheet. Used when processing is directed to a specific template. Used along with the xsl:otherwise and xsl:when elements to provide conditional testing. Copies the current node from the source document to the result tree.
Used to copy a result-tree fragment or node-set into the result tree. Declares a decimal-format that is used when converting numbers into strings with the format-number function.
Creates an element with the specified name in the output structure. Provides an alternative or fallback template when specific functionality is not supported by the XSLT processor being used for the transformation. Iterates over nodes in a selected node-set and applies a template repeatedly. Used to wrap a template body that will be used only when the if statement test returns a true value.
Allows an external XSLT style sheet to be imported into the current style sheet. Allows for the inclusion of another XSLT style sheet into the current style sheet. Declares a named key and is used in conjunction with the key function in XPath expressions. Used to output a text message and optionally terminate style sheet execution. Used to map a prefix associated with a given namespace to another prefix.
Used to format a number before adding it to the result tree or to provide a sequential number to the current node.
Used with the xsl:choose and xsl:when elements to perform conditional testing. Used to declare a parameter with a local or global scope. Preserves whitespace in a document. Used with xsl:for-each or xsl:apply-templates to specify sort criteria for selected node lists. Causes whitespace to be stripped from a document. This element must be the outermost element in an XSLT document and must contain a namespace associated with the XSLT specification and a version attribute. Defines a reusable template for producing output for nodes that match a particular pattern.
Used in the same manner as the xsl:stylesheet element. Writes out the value of the selected node to the result tree. Used to declare and assign variable values that can be either local or global in scope. Used as a child element of xsl:choose to perform multiple conditional testing. Used in passing a parameter to a template that is called via xsl:call-template. Applies a name to a template. The value must be a number that says the priority of the template.
Applies a mode to a template. Returns a node set that contains the current node as its only member. At this point in the template, the current node is the same as the context node. An example of this is shown next:. The predicate statement [. This will load data. Although the preceding document function example targets an external document, this function can also be used to target a node-set within the main XML document.
Aside from providing a string URI value, a node-set can be passed to access the remote document, as shown next:. Here are some examples of using this function:. The following function call returns 5, : format-number ," , ".
The following function call returns Similar to element-available, although this function checks whether specific functions are supported by the XSLT processor. This function is used in conjunction with the xsl:key element to return a node-set that has a specific name and value defined by the xsl:key statement. This function returns the value of the system property identified by the name passed as the argument. Accepts an XmlReader as well as an XmlSpace enumeration. The XmlResolver property can be used to specify a resolver class used to resolve external resources.
