In general, a XML text is interpreted as a label component. For example,

  Begin ${foo.whatever}

is equivalent to

  <label value="Begin ${foo.whatever}"/>

Components consider the nested content as proerty

However, a component can be designed to accept the nested text as the value of a component property. In other words, a component designer could decide to make ZK Loader interpret the nest text as the value of a predefined property. For example, Html is one of this kind of components, and

<html>Begin ${foo.whatever}</html>

is equivalent to

<html content="Begin ${foo.whatever}"/>

It is designed to make it easy to specify multiple-line value, so it is usually used by particular components that requires the multi-line value.

Here is a list of components that interprets the XML text as a property's value.

Component Name Property Name Method
a label A.setLabel(String)
button label Button.setLabel(String)
comboitem content Comboitem.setContent(String)
html content Html.setContent(String)
label value Label.setValue(String)
script content Script.setContent(String)
style content Style.setContent(String)
tab label Tab.setLabel(String) (since 5.0.7)

Note: Since 6.5.0, please use Tab.setLabel(String) instead

The nested XML content

[since 6.0.0]

Since ZK 6, components that consider the text as a property's value will accept the XML fragment. For example,

  <ol style="border: 1px solid blue">

In other words, you don't have to escape the special characters (< and >) with CDATA. In addition, you could leverage the full power of ZUML such as the zk element and the forEach attribute. For example,

    <li forEach="Apple, Orange">${each}</li>

Note that the nested content is part of the ZUML page, so it must be a legal XML document.
