Now, there might be alternatives like using JavaScript to do what needs to be done in JavaScript, before launching the transform passing extra info as xsl:param or enriching the input tree with extra attributes or elements. However, this support ended with IE9 at it was never a standard.

For replacing it, see stackoverflow. In particular, if you are only using IE, you could use msxsl:script. See msdn. Alternatively, you could simply re-write your XSLT to remove the need to call javascript functions. Add a comment. Active Oldest Votes. Improve this answer. MortenOdum MortenOdum 36 3 3 bronze badges. What is your "this"? For example, the Xalan-Java 2 XSLT processor from the Apache project has a redirect extension that allows developers to indicate that subsequent content should be sent to a new file, allowing an application to split an XML file into, say, different pages for each subject.

The recommendation doesn't stop there, however. These extensions take the form of extension functions, which are used in a way similar to XPath functions; and extension elements, which provide even more functionality.

Suppose you have an XML file that contains commerce information, and you want to transform it into a summary of orders. Unfortunately, the XML file doesn't actually contain any customer information. Instead, it contains a customer identifier that refers back to a database. This article will chronicle the building of a style sheet that uses extension functions and elements to allow calculations and a call to an external function that would, in a production application, return the customer information.

You can also download the source file and style sheet here , along with a command line script to execute the transformation. Let's start with a look at where we're starting out, and where we're going. The original XML file contains just the basics, as shown in Listing 1. The end result is a Web page that shows each order, including the extended price for each item and the customer information, as shown in Listing 2 and Figure 1. Figure 1 The final result. The extended prices and order total will come from extension functions, and the customer information will be provided by an extension elements.

We'll also use extension elements to "zero out" the totals between orders. We'll start by putting together the basic style sheet, with placeholders for the extensions. The overall format is laid out in Listing 3. Now let's add in the extensions to see how they're used. Later, we'll define the functionality that goes behind them. We'll start with the extension function. XPath has a number of built-in functions, such as round and concat. These functions can take XPath expressions as arguments, and because they themselves are XPath expressions, we output them using the value-of element.

For example, we could round off prices to the nearest dollar using the round function:. In this same way, we can add a new function, which we'll define later, as shown in Listing 4. Here, we defined two functions: totalCost , which takes no arguments; and getExtPrice , which takes as arguments the quantity and price children. The getExtPrice function also updates the running total value, representing the total cost of the order.

XPath normally converts elements to text values, but eventually we'll want to perform arithmetic on them, so we'll use XPath's built-in number function to change their type before passing them to the script. Both functions have a namespace prefix, totalSys , to tell the processor that we're not dealing with built-in functions.

The namespace itself doesn't matter, as long as it's unique. Ultimately, the processor will output the values returned by these functions just as if it were one of the built-in functions. The purpose of an extension element is a bit different from that of a function. Although an extension element can return a value for output, elements are usually used more to cause something to be done.

For example, we have two things that we want done: We want to retrieve the customer information from the database, and we want to reset the order total for each order. The elements are added in Listing 5. In the first case, we're simply going to return customer information. In the second, we're using a custom attribute to pass information to the script. This element won't actually output any information, but it will reset the running total for each order.

Now, all we need is a way to tell the processor what it's supposed to do when it encounters these extensions.

The maximum size of files that can be uploaded is determined by the Organization. MaxUploadFileSize property. This property is set in the Email tab of the System Settings in the Dynamics application. This setting limits the size of files that can be attached to email messages, notes, and web resources. The default setting is 5 MB. You can use ten file formats to create web resources.

The following table lists each file format, the allowed file extensions, and the type value that you use for each. The following sample shows how to use it. The Xrm. To enable this, we recommend that you use a consistent naming convention for the web resources that reflect a virtual file structure.

From another web resource, you should always use relative URLs to reference each other. When a user belongs to more than one organization on a server, this path will always refer to the users default organization. The application will process this URL and return the file that contains the latest version of the web resource. This URL will look like this:. The version value is updated when you publish customizations and ensures that the browser uses the latest cached version of the web resource.

Because of this, use a relative path to a web resource, the Xrm. When you write code to reference a web resource that works for Dataverse, you should use the getClientUrl function. A web resource control configured to use a certain number of rows will have different heights in a Unified Client application compared to a web client application. This is because there is a difference in the height of a row between Unified Interface and web client.

If a form is needed in both the web client and Unified Interface, you can use different forms in the Unified Interface app and the web client app with the control configured to use the appropriate number of rows in each form.

Skip to main content. Contents Exit focus mode. The central idea is to treat a data structure as a "template" and transform it, using another data structure as context, to produce an output data structure.

The language design is inspired by jq, XPath, and XQuery. Inspired by the 'location path' semantics of XPath 3. Provides a recursive, pattern-matching approach to transforming JSON data. Transformations are defined as a set of rules which match the structure of a JSON object. When a match occurs, the rule emits the transformed data, optionally recursing to transform child objects. It is a single-file node. Jsawk is like awk, but for JSON.

You work with an array of JSON objects read from stdin, filter them using JavaScript to produce a results array that is printed to stdout. Stapling Last Commit Sep 16, The main source of inspiration behind JSONiq is XQuery, which has been proven so far a successful and productive query language for semi-structured data. Try JOLT. XML's fewer token recognition comparisons means it's optimized for declarative transformation, whereas more comparisons, being like switch statement, for speed reasons assume speculative branch prediction that imperative code in scripting languages is useful for.

As direct consequence, for different mixes of semi-structured data, you may want to benchmark XSLT and javascript engines' performance as part of responsive pages. W3's decision ought to be based on better analysis. It's not template-based like XSLT, but more concise. Have a look at jsonpath-object-transform.

XSLT 3. To say lack of tools suggest lack of need is just begging the question. And why pay attention to an OS that big game and hardware companies don't develop for? But that's not the optimal solution, is it? Doing that with traditional javascript programming can become a pain in the arse. In fact, I have implemented a "stone-age" approach to XSLT, using substring parsing to interpret some basic commands for javascript, like calling a template, process children, etc.

Otherwise you'll end up having to design a parser for your own custom templating language. Having walked through that path, I can tell you that it's not pretty. Update Nov 12, : After a couple of weeks working on my parser, I've been able to optimize it. Templates are parsed beforehand and commands are stored as JSON objects.

The code is around 1K lines for the editor it's for a private project so I can't share it and around lines for the JSON transformation code includes iteration commands, simple comparisons, template calling, variable saving and evaluation. I plan to release it under a MIT license. Drop me a mail if you want to get involved. As yet another new answer to an old question, I'd suggest a look at DefiantJS. The "Templating" section of the documentation includes this example:.

There is now! I recently created a library, json-transforms , exactly for this purpose:. This transform is composed of three rules. The first matches any automobile which is made by Honda, emitting an object with a Honda property, then recursively matching.

The second rule matches any object with a maker property, outputting the model and year properties. The final is the identity transform that recursively matches. I've been really tired of the enormous amount of JavaScript templating engines out there, and all their inline HTML-templates, different markup styles, etc.

It's fast too, not as fast as JavaScript template engines in Chrome, but in most other browsers it's at least as fast as the JS engine alternative for larger data structures. It's a transform language where you write the fixed part of the output in JSON syntax, then insert expressions to compute the values you want to insert in the template.

Note that the demo also relies on JavaScript 1. I wrote a dom adapter for my jackson based json processing framework long time ago. It uses the nu. The resulting dom tree works with the java xpath and xslt facilities. I made some implementation choices that are pretty straightforward. For example the root node is always called "root", arrays go into an ol node with li sub elements like in html , and everything else is just a sub node with a primitive value or another object node.

Verson 3 of XPath 3. This seems to be available in the commercial version of Saxon, and might at some point be included in the HE version. I would want the transformation scripts to be external from the tool, text based, and preferably a commonly used language. I wonder if SQL could be a suitable alternative. Just some thoughts so far. Not too sure there is need for this, and to me lack of tools suggests lack of need.

StaxMan XSLT is a standard that has actual implementations in many languages and platforms, my questions targets a similar endeavor. NicolasLeThierryd'Ennequin Agreed. The XML ecosystem of tools is also heavy on Java devs, which turns away even more people.

I would love a JSON equivalent! I strongly disagree with the closing of this answer. Show 10 more comments. Active Oldest Votes. Interesting idea.
