Apply an XML template with slots named a and b:

An equivalent form using TemplateApply:

XMLTemplate supports the same syntax as StringTemplate; expressions in <*…*> are evaluated when the template is applied:

Include a template slot as well as an expression in the template string:

An equivalent syntax using XML tags:

String template syntax is useful when you need to inject data inside XML attributes:

File is fully supported:

Templates can be hosted in the Wolfram Cloud:

The second argument of XMLTemplate can be used to bound data to the template:

URL can be used to fetch templates:

<wolfram:slot id='...' inserter='...'>...</wolfram:slot>

Simple usage:

Working with default and inserter:

<wolfram:expr inserter='...'>...</wolfram:expr>

Simple usage:

Working with data and inserter:

<wolfram:if test='...'>...</wolfram:if>

Test can be any expression:

<wolfram:which><wolfram:if test='...'>...</wolfram:if></wolfram:which>

Use "which" to nest multiple "else if" clauses:

<wolfram:sequence values='...' ...>...</wolfram:sequence>

Basic usage:

Using named variables:

Using the insertion function:

Using the default value (a StringTemplate):

Using a delimiter:

<wolfram:with key$1='val$1' ...>...</wolfram:with>

<wolfram:get path='...'><wolfram:slot id='...'/>...</wolfram:get>

Include a template from "path". "Path" is a StringTemplate:

Change insertion and combiner functions for the output:

Extending a template. Example of a template for an HTML page:

Using "get" to override slots:

<wolfram:template ...>...</wolfram:template>

Use "template" to create a fragment that overrides the insertion and combiner functions:

Combine templates and edit an external template:

<wolfram:comment>...</wolfram:comment>

<wolfram:verbatim>...</wolfram:verbatim>

Use "verbatim" to avoid parsing. An optional insertion function is allowed:

XMLTemplate evaluates to a TemplateObject:

Data in the second argument of XMLTemplate takes precedence over arguments in TemplateApply:

You can deploy an XMLTemplate to the cloud. When you visit the URL, TemplateApply will render the template on each visit:
