HI Daniel,
Its not preceeded by white spaces but "\n" is taken as sibling.
In book.xml <programlisting role="formDataModel">dsadsd fdfsdfdsf
dfds</programlisting>
<programlisting role="template"><#if cargo.weight <
<emphasis>100</emphasis>>Light cargo</#if></programlisting>
I am trying to get the programlisting with role formDataModel as
previousSibling. But the "\n" is returned as the sibling. To confirm the same I
just checked it with node.previousSibling().previousSibling() and I am able to
get to formDataModel.
What should we need to do for this here ?
I have also added a key with @@prev in ElementModel and that works fine.
Pradeep.
