[PATCH 0/3] MR10225: Draft: libs/xml2: Tolerate embedded XML declarations inside elements.
Windows MSXML tolerates nested <?xml?> processing instructions inside elements, but libxml2 rejects them with XML_ERR_RESERVED_XML_NAME. When an embedded <?xml is encountered inside an element, consume everything up to the parent's closing tag and emit it via the SAX characters callback as a text node, matching Windows MSXML behavior where the content after the embedded <?xml?> is treated as text. This is needed for applications like Adobe Creative Cloud installer that use embedded XML declarations in their data. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10225

From: lucas persson <lucas.persson@uc.se> Address review feedback: - Remove the content-consumption approach in xmlParsePI that treated everything after <?xml?> as text. Instead, just let libxml2 handle <?xml ...?> as a regular processing instruction, which matches Windows MSXML behavior more closely. - Rewrite tests to validate DOM structure: check node types (NODE_PROCESSING_INSTRUCTION, NODE_ELEMENT), verify text content, and assert exact child node counts. --- dlls/msxml3/tests/domdoc.c | 248 ++++++++++++++++++++++++------------- libs/xml2/parser.c | 79 +----------- 2 files changed, 163 insertions(+), 164 deletions(-) diff --git a/dlls/msxml3/tests/domdoc.c b/dlls/msxml3/tests/domdoc.c index 3944ec81088..a0b465f9bca 100644 --- a/dlls/msxml3/tests/domdoc.c +++ b/dlls/msxml3/tests/domdoc.c @@ -14476,41 +14476,28 @@ static void test_embedded_xml_declaration(void) { IXMLDOMDocument *doc;
