我需要一个XPath来获取所有的ChildNodes(包括文本元素,注释元素和子元素)没有父元素。任何帮助
示例示例:
<DOC> <PRESENTEDIN> <X> First Text Node #1 <y> Y can Have Child Nodes # <child> deep to it </child> </y> Second Text Node #2 <z/> </X> <EVTS> <evt/> <evt> <mtg_descr> SAE 2006 World Congress & Exhibition </mtg_descr> <sess_descr> Advanced Hybrid Vehicle Powertrains (Part 1 of 5) </sess_descr> <loc> Detroit,MI,United States </loc> <sess_prod_grp_cd> TSESS </sess_prod_grp_cd> <sess_evt_name> P13 </sess_evt_name> <sess_gen_num> 138352 </sess_gen_num> <mtg_start_dt> 04/03/2006 </mtg_start_dt> <mtg_end_dt> 04/06/2006 </mtg_end_dt> <desig> CONGRESS-2006 </desig> </evt> </EVTS> <EVTTYPE>PAPER</EVTTYPE> <SUPERTECH> <![CDATA[C8585]]> </SUPERTECH> </PRESENTEDIN>
XPATH TRIED
1. $doc/PRESENTEDIN/X 2. $doc/PRESENTEDIN/X/descendant::* 2. $doc/PRESENTEDIN/X/self::*
预期输出
First Text Node #1 <y> Y can Have Child Nodes # <child> deep to it </child> </y> Second Text Node #2 <z/>
我不想
<X> First Text Node #1 <y> Y can Have Child Nodes # <child> deep to it </child> </y> Second Text Node #2 <z/> </X>
从XPath(
http://www.w3.org/TR/xpath/#location-paths)的文档:
原文链接:/xml/293690.html
child::*
selects all element
children of the context node
child::text()
selects all text node
children of the context node
child::node()
selects all the
children of the context node,whatever
their node type
所以我想你的答案是:
$doc/PRESENTEDIN/X/child::node()
如果你想要一个flatten数组的所有嵌套节点:
$doc/PRESENTEDIN/X/descendant::node()
