From 58232ce10296db86168e2e7bbc6d7a3a789c7529 Mon Sep 17 00:00:00 2001 From: "Flavio S. Glock" Date: Fri, 1 May 2026 17:07:38 +0200 Subject: [PATCH 1/7] feat(xml-libxml): improve XML::LibXML test suite pass rate Add several missing methods and fix several bugs: New methods/aliases: - getElementsByTagName/NS/LocalName on Document nodes (in addition to Element) - getChildrenByTagName, getChildrenByLocalName, getChildrenByTagNameNS - createPI alias for createProcessingInstruction - actualEncoding alias for documentEncoding - docToFH (toFH method) to write document to a Perl filehandle - parse_string now accepts scalar refs (\$xml) and binary UTF-16/UTF-32 XML Bug fixes: - getElementsByLocalName on Document now includes document element itself - parse_string now dereferences unblessed scalar refs (\$string) - parse_string detects binary-encoded XML (UTF-16/UTF-32 with or without BOM) and parses as byte stream for correct encoding detection - serializeNode (toString) now removes encoding= attribute when setEncoding() was called with no args (explicit encoding clear) - serializeNode adds newline after XML declaration to match libxml2 output - setEncoding/getEncoding now correctly store parsed document encoding - Correct UDATA_ENCODING sentinel handling RuntimeScalar.java: - hashDerefRaw() added to bypass Perl %{} overload when accessing internal node hash (prevents infinite recursion in XML::LibXML::Element %{} overload) Result: t/03doc.t goes from ~5/193 to 175/193 pass; overall full-pass count increases from ~22 to 37 test files (plus 7 partial).

Glock" Date: Fri, 1 May 2026 18:34:40 +0200 Subject: [PATCH 2/7] feat(xml-libxml): push parser, SAX generator, and DOM fixes Implement push/incremental parsing and SAX event generation for XML::LibXML, bringing the upstream test suite pass rate from 40.9% to 53.7% (1307/2435). - Add `PushContext` inner class to buffer incremental XML chunks - Implement `_start_push`, `_push`, `_end_push` Java methods - Implement `_parse_xml_chunk` to parse well-balanced fragments (wraps in synthetic root, creates DocumentFragment) - Add Perl-level `init_push`, `push`, `parse_chunk`, `finish_push`, `parse_xml_chunk`, `parse_balanced_chunk` methods to XML/LibXML.pm - Add `_init_callbacks` / `_cleanup_callbacks` stubs for SAX compat - Implement `_fire_sax_events` / `_fire_sax_element` in SAX.pm - Walks DOM tree and fires SAX2 events to the handler chain - Handles Text, CDATA (start_cdata/end_cdata), Comment, PI, DocumentFragment, Element node types - Uses `getData()` for node text (works on Comment, CDATA, Text) - Builder.pm now receives events and builds a real DOM result - `attributes()` in LIST context now returns individual Attr nodes (flat list) instead of a NamedNodeMap object - Add `appendText($text)` to Node: creates + appends a text node child - Add `createRawElement` / `createRawElementNS` as aliases to `createElement` / `createElementNS` on Document - `setNamespace($uri, $prefix, $act)`: always add xmlns: declaration attribute, even when `$act` is false - `insertBefore` / `insertAfter`: auto-import nodes from foreign documents (fixes WRONG_DOCUMENT_ERR when appending fragments from different parsers) - Add `importNodeIfNeeded` helper for cross-document node moves - `_parse_html_string` now self-closes void HTML elements (base, br, meta, img, input, hr, link, etc.) before XML-parsing, enabling HTML parsing tests Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> --- .../runtime/perlmodule/XMLLibXML.java | 562 +++++++++++++++++- src/main/perl/lib/XML/LibXML.pm | 121 ++++ src/main/perl/lib/XML/LibXML/SAX.pm | 96 ++- 3 files changed, 749 insertions(+), 30 deletions(-) diff --git a/src/main/java/org/perlonjava/runtime/perlmodule/XMLLibXML.java b/src/main/java/org/perlonjava/runtime/perlmodule/XMLLibXML.java index 3655ffb9c..618356144 100644 --- a/src/main/java/org/perlonjava/runtime/perlmodule/XMLLibXML.java +++ b/src/main/java/org/perlonjava/runtime/perlmodule/XMLLibXML.java @@ -3,10 +3,12 @@ import org.perlonjava.runtime.operators.ReferenceOperators;

Glock" Date: Fri, 1 May 2026 20:51:39 +0200 Subject: [PATCH 3/7] feat(XML::LibXML): fix t/10ns.t namespace tests (135/137 passing) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major improvements to XML::LibXML namespace handling: - When removing a namespace declaration (`setNamespaceDeclURI('xxx', undef)`), now cascades to rename element and all child elements/attrs using that prefix to have no namespace. Added `removePrefixFromSubtree` helper. - `setNamespaceDeclPrefix` on a non-existent prefix now returns 1 (no-op) instead of dying. - `appendChild` now strips redundant namespace declarations from the child node when the same prefix→URI is already declared on an ancestor. Added `reconcileNamespaces` helper. - `removeChild` now re-adds namespace declarations for prefixes used by the detached node's attributes/prefix that were only declared in the former parent context. Added `readdMissingNsDecls` helper. - New helper used by both reconciliation paths and `getNamespaceDeclURI`. - For non-empty prefixes, also detects implicit declarations from an ancestor element's own namespace binding (createElementNS without explicit xmlns). - Extended the namespace URI fallback to non-empty prefixes: when an element uses a prefix but no ancestor declares it, `getAttribute('xmlns:prefix')` returns the namespace URI (synthesised from the element's own NS binding). - Both empty and non-empty prefix fallbacks skip synthesis when an ancestor already declares the same prefix→URI. - Handles empty/null ns argument to remove namespace and prefix from element or attribute nodes via `renameNode(el, null, localName)`. - `getElementById` on Document: tree walk checking xml:id and id attributes - `setAttributeNodeNS` on Element: wrapper for DOM setAttributeNodeNS - `getName` on Node: alias for nodeName - `replaceChild` now adopts the new child if it belongs to a different document (matches libxml2 behavior), fixing WRONG_DOCUMENT_ERR. Test results: 135/137 passing in t/10ns.t (up from ~97/137). Remaining 2 failures: libxml2-specific quirks (getElementById after node detachment, setAttributeNodeNS declaring on root element).

Perl's `my @arr = $node->childNodes` +puts the NodeList object itself into `@arr[0]` (scalar), not the individual nodes. + +**Expected behaviour**: +- **List context**: returns a flat list of individual `XML::LibXML::*` node objects. +- **Scalar context**: returns an `XML::LibXML::NodeList` blessed reference. + +**Fix**: In `XMLLibXML.java`, check `ctx == RuntimeContextType.LIST` and return +individual wrapped nodes (similar to how `findnodes` already does this). + +```java +public static RuntimeList childNodes(RuntimeArray args, int ctx) { + NodeList children = getNode(args.get(0)).getChildNodes(); + if (ctx == RuntimeContextType.LIST) { + RuntimeList result = new RuntimeList(); + for (int i = 0; i < children.getLength(); i++) + result.add(wrapNode(children.item(i))); + return result; + } + RuntimeArray arr = new RuntimeArray(); + for (int i = 0; i < children.getLength(); i++) + RuntimeArray.push(arr, wrapNode(children.item(i))); + return ReferenceOperators.bless(arr.createReference(), + new RuntimeScalar("XML::LibXML::NodeList")).getList(); +} +``` + +Also add `getChildnodes` as an alias (used in t/16docnodes.t). + +--- + +### 2. Missing `$XML::LibXML::skipXMLDeclaration` in `toString` — HIGH IMPACT + +**Affects**: t/02parse.t stops producing output after test 181 (all remaining +tests require round-trip via `toString` with `$skipXMLDeclaration = 1`). + +**Root cause**: `documentToString` and `toString` (node serialization) ignore +the `$XML::LibXML::skipXMLDeclaration` package variable. + +**Fix**: In `XMLLibXML.java::serializeNode`, read the Perl global: + +```java +private static String serializeNode(Node node, boolean format, boolean withDecl) { + if (withDecl) { + RuntimeScalar skip = GlobalVariable.getGlobalVariable("XML::LibXML::skipXMLDeclaration"); + if (skip != null && skip.getBoolean()) withDecl = false; + } + // ... existing Transformer code ... +} +``` + +Also respect `$XML::LibXML::skipDTD` (suppress DOCTYPE in output) and +`$XML::LibXML::setTagCompression` (self-closing vs empty element style). + +--- + +### 3. `keep_blanks(0)` does not strip whitespace text nodes — HIGH IMPACT + +**Affects**: t/02parse.t `toString` round-trip tests (` ` → ``). + +**Root cause**: `setIgnoringElementContentWhitespace(true)` only strips +*element content whitespace* (whitespace in element-only content models defined +by DTD). For XML with no DTD, JAXP cannot classify content models, so the +flag does nothing. + +**Fix**: After parsing with `keepBlanks=false`, walk the DOM tree and remove +all `Text` nodes that contain only whitespace (i.e., `node.getNodeValue().trim().isEmpty()`). +Implement this as a post-parse helper `stripBlankTextNodes(Document doc)`. + +--- + +### 4.

Missing `XML::LibXML::XPathExpression->new` — HIGH IMPACT + +**Affects**: t/09xpath.t, t/30xpathcontext.t (stop at first call). + +**Root cause**: No `new` method registered for the `XML::LibXML::XPathExpression` class. + +Upstream `XML::LibXML::XPathExpression->new($expr_string)` compiles an XPath +expression for reuse. JDK has no compiled-XPath type separate from +`XPathExpression` objects, but we can store the string and compile lazily. + +**Fix**: Register a `new` method in `XMLLibXML.java`: +```java +module.registerMethodInPackage("XML::LibXML::XPathExpression", "new", "xpathExprNew"); +module.registerMethodInPackage("XML::LibXML::XPathExpression", "expression", "xpathExprStr"); +``` +Store the expression string in the blessed hash. + +--- + +### 7.

Glock" Date: Fri, 1 May 2026 21:15:52 +0200 Subject: [PATCH 4/7] feat(XML::LibXML): fix t/10ns.t to 137/137 passing Two fixes in XMLLibXML.java: 1. setAttributeNodeNS: when setting an attribute whose namespace prefix is not yet declared in the ancestor chain, libxml2 places the xmlns: declaration on the document root element (not on the receiving element). Emulate this by calling lookupNamespaceURI after setAttributeNodeNS; if the prefix is still undeclared, add it to the document root. 2. getElementById: libxml2 maintains a persistent ID index so nodes are still findable after they are detached from the tree. Emulate this via a per-Document HashMap stored in setUserData("__xmlIdCache__"). Each successful live-tree lookup refreshes the cache; if the live walk finds nothing, the cache is consulted (returning detached nodes). Result: t/10ns.t now passes 137/137 (was 135/137).
