Xerces-C:从 v2.x 迁移到 v3.x? [英] Xerces-C: Migration from v2.x to v3.x?
问题描述
我想将一个项目(我不太熟悉的遗留代码)从 Xerces-C v2.x 迁移到 v3.x.
I would like to migrate a project (legacy code which I am not quite familiar with) from Xerces-C v2.x to v3.x.
事实证明，Xerces-C v3 删除了 DOMBuilder 类.迁移档案告诉我:
It turns out that Xerces-C v3 dropped the DOMBuilder class. The migration archive tells me this:
...许多 DOM 接口(DOMBuilder、DOMWriter、DOMInputSource 等)被替换为最终 DOM Level 3 规范一致性工作的一部分.
...a number of DOM interfaces (DOMBuilder, DOMWriter, DOMInputSource, etc.) were replaced as part of the the final DOM Level 3 specification conformance work.
那很好.但是有没有关于如何将依赖于这些类的代码迁移到新 API 的指南?
That's nice. But is there any guide on how to migrate code that relies on these classes to the new API?
推荐答案
已移除 API 的替换:
Replacements for removed APIs:
使用
XercesDOMParser或DOMLSParser而不是DOMBuilder(更多信息):
Use
XercesDOMParserorDOMLSParserinstead ofDOMBuilder(more info):
xercesDOMParser->setCreateCommentNodes(true);
xercesDOMParser->setCreateCommentNodes(true);
使用 DOMLSSerializer 而不是 DOMWriter:
DOMLSSerializer* writer = ((DOMImplementationLS*)impl)->createLSSerializer();DOMConfiguration* dc = writer->getDomConfig();dc->setParameter(XMLUni::fgDOMErrorHandler,errorHandler);dc->setParameter(XMLUni::fgDOMWRTDiscardDefaultContent,true);
DOMLSSerializer* writer = ((DOMImplementationLS*)impl)->createLSSerializer(); DOMConfiguration* dc = writer->getDomConfig(); dc->setParameter(XMLUni::fgDOMErrorHandler,errorHandler); dc->setParameter(XMLUni::fgDOMWRTDiscardDefaultContent,true);
使用 DOMLSInput 而不是 DOMInputSource.
