evaluate

is a tag that evaluates input to the Wolfram Kernel and inserts the formatted result in the output page.

Details

The evaluate tag is one of the most important tags for creating web material with MSP. A user places the tag inside of a MSP page, the body of the tag is evaluated and then the result is formatted and placed into the response to the web response. More information on the operation of the tags can be found in the section MSP Tags.
There is a large collection of Wolfram Language commands that can be used inside the tags, such as evaluate. These provide useful functionality for creating web material with the Wolfram Language. They are useful in various ways, such as processing request parameters that are the input from a web user, formatting results and using web features such as uploading files and HTTP sessions. More information can be found in the section MSP Web Functions.
The results of the computation of the body of an evaluate tag can be formatted in a variety of ways, including into text, HTML fragments or images. More information on formatting can be found in the section on formatting.

The following example evaluates an integral and inserts the formatted result in the webpage:

<msp:evaluate>
    Integrate[ expr, {var, 0, Infinity}]
</msp:evaluate>
