Preprocessing InstructionsLocate this document in the navigation structure

Preprocessing intructions are processed by the XML preprocessor when it traverses the view's XML DOM.

Note

A model name can be seen as a variable with a value that consists of two parts: a model instance and a binding context path.

You can base conditions on the available variables. XML attributes that represent an available binding are replaced automatically.


In this section:
    with
    The <template:with> instruction can be used to change a variable's value or to add a variable with a new name.
    repeat
    The <template:repeat instruction iterates the sap.ui.model.ListBinding given by the list attribute.
    if
    The <template:if> instruction evaluates a condition expressed via existing SAPUI5 data binding features, such as extended syntax; in the preprocessing it is removed or replaced by its child elements based on the value of this condition.
    alias
    The <template:alias> instruction can be used to define a shortcut alias name for a JavaScript value, for example a static helper class, a formatter function, or a helper function.
    require
    The template:require attribute can be used at the root element of an XML template view or fragment to specify a space separated list of module names for jQuery.sap.require. You do not need to call jQuery.sap.require("sap.ui.model.odata.AnnotationHelper") before use as it is automatically available.
    Replacement of Bindings
    For attributes, SAPUI5 binding expressions are used instead of preprocessing instructions. If the value of an XML attribute represents a valid SAPUI5 binding which refers to currently available model (= <variable>) names only, the binding is evaluated and the result is written back into the XML attribute.
    XML Fragments
    SAPUI5 fragments of type XML are used in the context of XML templating to provide reuse parts for templates.
    Extension Points
    Extension points can be used in XML templating to extend the standard with custom content.
