In XBL, what is the difference between xbl:attr and xbl:text?

I am using Orbeon Forms, and here is some sample code from xbl-simple.xhtml

XHTML with XBL Component

<foo:test id="my-test-1" myref="value1" foobar="en fr"/>

I am trying to understand the difference between (xbl:text=foobar vs value=foobar)

<xxforms:variable name="foobar" xbl:attr="xbl:text=foobar"/>

vs

<xxforms:variable name="foobar" xbl:attr="value=foobar"/>

If they are same then where exactly is xbl:text useful?

Solution

  • The two are a bit different:

    <xxforms:variable name="foobar" xbl:attr="xbl:text=foobar"/>

    translates to:

    <xxforms:variable name="foobar">en fr</xxforms:variable>

    And:

    <xxforms:variable name="foobar" xbl:attr="value=foobar"/>

    translates to:

    <xxforms:variable name="foobar" value="en fr"/>

    In the first case, the value of the variable is the constant string "en fr".

    In the second case, it is probably an invalid XPath expression!
