Hello,
I'm trying to write a macro command to remove all elements matching a given
XPath expression using XXE 5.9.0.
This is the command definition in my customization file (0docbook5.xxe):
<command name="db5.removeUnusedParts">
<macro repetable="true" undoable="true" label="Remove Unused Parts">
<sequence>
<command name="xpathSearch"
parameter="//*[@revisionflag='off']" />
<command name="delete" />
</sequence>
</macro>
</command>
I assign it to a button on the UI
<button toolTip="Remove Unused Parts"
icon="../config/common/icons/up.png">
<command name="db5.removeUnusedParts" />
</button>
The button shows up and it is enabled when I select an element in the
document. Clicking the button removes only the first matching node from the
XPath node-set result.
So, a few questions:
1) How can I have the button always enabled as opposed to enabled only when
selecting an element? The idea is to actually make this not a button, but a
menu entry of the "DocBook" (XML) menu.
2) If xpathSearch returns a node-set, why isn't the delete command applied
to all nodes in the node-set and it's only applied to the first matching
node? How can I 'loop' through all nodes returned in the node-set applying
the delete command on them? Will I have to forget about this macro command
and write a custom Java command instead (Not that I do not know how to do
it, I'm just trying to solve this with what XXE already has)?
All of the examples I've found on the documentation apply commands to a
single node, not to a node-set. I've searched the docs too and found no
"loop-like" construct to write commands (I'm pretty sure there's good
reasons for that... but I need one :-))
Thanks in advance for your answers.
