how clear body content placed within custom tag?
<abc:mytag display="true"> <b> clear content </b> <abc:mytag />
based on display="true" boolean flag in tag handler, want clear out content "clear content". tried:
if(display){ getbodycontent(); } else seek { getbodycontent().clear(); } grab (ioexception e) { // todo auto-generated grab block e.printstacktrace(); }
but throwing null pointer exception
if have reference custom element can do
for (node child; (child = mycustomelement.getfirstchild()) != null;) { mycustomelement.removechild(child); }
if need reference custom element can like
element mycustomelement = mydocument.getelementsbytagnamens(namespaceforabc, "mytag");
or if aren't using xml namespaces, can do
element mycustomelement = mydocument.getelementsbytagname("abc:mytag");
java jsp jstl
