come faccio da questo file ad estrapolare delle select?
dovrei avere una selec principale che mi scelga tra:
General Literature
o
Hardware
poi in base a quale scelgo mi sevirebbe una selcet che secliesse il sotto nodo ed un'altra select, nel caso in cui il sotto nodo ha altri sotto nodi per sempio in questo caso:
codice:
<node id="A." label="General Literature">
<isComposedBy>
<node id="A.0" label="GENERAL">
<isComposedBy>
<node label="Biographies/autobiographies"/>
<node label="Conference proceedings"/>
<node label="General literary works (e.g., fiction, plays)"/>
</isComposedBy>
</node>
<node id="A.1" label="INTRODUCTORY AND SURVEY"/>
<node id="A.2" label="REFERENCE (e.g., dictionaries, encyclopedias, glossaries)"/>
<node id="A.m" label="MISCELLANEOUS"/>
</isComposedBy>
</node>
//se volessi scegliere: Conference proceedings questo mi dovrebbe apparire nella terza select. Avete consigli su come fare? grazie
