Hi all,
some days ago somebody asked about how to update an attribute of a
given element. If the attribute node already exists then this is
no problem with XUpdate:
<xupdate:modifications xmlns:xupdate="...">
<xupdate:update select="/xpath/to/[EMAIL PROTECTED]">
new value
</xupdate:update>
</xupdate:modifications>
Updating a possibly non-existent attribute (as well as element) is
somewhat difficult, because this is not the use case of XUpdate.
Either one inserts (after|before) or append an element|attribute node
or one updates an existing element|attribute node. Its not possible
(with justifiable expense) to find out whether the selected node does
not exist or a node en route. But we need to know exactly this to
decide whether to create the node (i.e. update with implicite creation)
or not.
Or did I ignore some other facts?
Regards,
Lars
