[PATCH v7 0/3] MR10025: mshtml/msxml3: Add XMLSerializer, embedded XML declaration handling
This patchset adds XMLSerializer support and fixes several compatibility issues for Adobe Creative Cloud installer and similar applications. XMLSerializer implementation (mshtml) - Implements the `IXMLSerializer` interface with `serializeToString()` method - Allows JavaScript to serialize DOM elements to XML strings Embedded XML declaration handling (msxml3) - Adds CDATA wrapping for embedded `<?xml?>` declarations inside elements - Windows MSXML tolerates these nested declarations but libxml2 rejects them - The preprocessing step wraps problematic content in CDATA sections before parsing ~~DISPATCH_METHOD|DISPATCH_PROPERTYGET fixes (jscript/mshtml)~~ This was already done !10004 Also added tests for XMLSerializer (empty elements, text nodes, special characters, nested elements, multiple children), embedded XML declaration handling (multiple declarations, deeply nested, encoding attributes, self-closing elements) and DISPATCH_METHOD|DISPATCH_PROPERTYGET behavior in both quirks and standards modes - Filip Bakreski -- v7: mshtml/msxml3/tests: Add tests for XMLSerializer and embedded XML declarations. libs/xml2: Tolerate embedded XML declarations inside elements. mshtml: Add IXMLSerializer implementation. https://gitlab.winehq.org/wine/wine/-/merge_requests/10025

@nsivov i applied a patch to libs/xml2 that does this, bee18763 was this what you had in mind? The part about removing XML_ERR_RESERVED_XML_NAME check, yes, maybe. The other part I don't understand. Tests don't show what actually is being returned for such nodes. Is that the usual processing instruction node with "xml" target? I thought simply removing restriction on <?xml nodes in the content would be enough.

Is that the usual processing instruction node with "xml" target? I thought simply removing restriction on <?xml nodes in the content would be enough. Simply removing the XML_ERR_RESERVED_XML_NAME restriction was the first thing I tried, but it's not sufficient. The problem is what happens after the \<?xml?\> PI is parsed. If we just remove the fatal error and let it parse as a normal PI with target "xml", the parser then continues and parses \<DriverInfo\>\<Name\>test\</Name\>\</DriverInfo\> as child elements of \<driverXMLData\>. But from testing it appears that Windows MSXML treats the entire content after the embedded \<?xml?\> as text, the application expects to retrieve it as a string, not as a DOM subtree. That's why the previous approach wrapped it in CDATA.
The current patch replicates that behavior in libxml2, when an embedded \<?xml is encountered inside an element, it consumes everything up to the parent's closing tag and emits it via the SAX characters callback, so it becomes a text node. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10025#note_128932

Currently this fails Windows CI for newly added tests - it fails to load those documents. We'll need to resolve that first before moving further.

Thank you Filip for this MR :). I hope this MR gets approved soon. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10025#note_129109
I created !10063 for MSHTML parts, let's move further MSHTML discussion there. It's mostly extracted from this MR, but I also made headers compatible with winsdk and simplified tests. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10025#note_129297
Remaining bits are all in msxml3. In order to move this forward we'll need some working tests, or at least a document similar to the one that fails parsing. Current tests in this MR are failing on Windows, so can't be used to validate proposed changes. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10025#note_129532
