Edit report at https://bugs.php.net/bug.php?id=66937&edit=1 ID: 66937 Updated by: cmb@php.net Reported by: sites at hubmed dot org Summary: XSLTProcessor::transformToDoc causes separation of doctype and source document -Status: Assigned +Status: Open -Type: Bug +Type: Documentation Problem Package: XSLT related Operating System: OS X PHP Version: 5.5.10 -Assigned To: cmb +Assigned To: Block user comment: N Private report: N New Comment: I have serious doubts that we should fix this (without also fixing other potential modifications to the source document), so I'm reclassifying as documentation issue.

A workaround is to clone the DOMDocument object before calling transformToDoc on it, but this shouldn't be necessary. I notice that the "nextSibling" property of the DOMDocumentType object is lost during the transformation. ===== Tested with PHP 5.5.10 and 5.4.24. libxml2 Version => 2.9.0 libxslt Version => 1.1.28 Test script: --------------- https://gist.github.com/hubgit/9669288 Input: <?xml version="1.0"?> <!DOCTYPE article PUBLIC "-//example//EN" "http://example.org/dtd"> <article/> Expected result: ---------------- <?xml version="1.0"?> <!DOCTYPE article PUBLIC "-//example//EN" "http://example.org/dtd"> <article/> Actual result: -------------- <?xml version="1.0"?> <article/> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66937&edit=1
