</product_tracking_information_module>
and the code to do that, where doc is the xmldom parsed Document 以及执行此操作的代码,其中doc是xmldom解析的Document
var ptimdom = new dom().parseFromString(ptimxml.toString());
var nodesPTIM = xpath.select("//productData//productDataRecord//module//product_tracking_information_module", doc);
doc.replaceChild(ptimdom,nodesPTIM[0]);
but the result is that the doc after this is the second xml only and the full data is lost. 但是结果是此后的文档仅是第二个xml,并且所有数据都丢失了。
What am i doing wrong? 我究竟做错了什么?
试试nodesPTIM[0].parentNode.replaceChild(ptimdom, nodesPTIM[0])
,即在要替换的元素的parentNode上调用replaceChild方法。
