> A deep review of the XML DSL parser and dumper (camel-xml-io,
> camel-xml-io-util) found the bugs below. Each one was reproduced against
> 4.23.0-SNAPSHOT and has a test that fails without the fix
> (MXParserEdgeCasesTest, XmlStreamReaderTest, DumpModelEdgeCasesTest).
> # *Two CDATA sections in a row followed by text duplicate the second one, or
> fail the parser.* <constant><![CDATA[x]]><![CDATA[y]]>z</constant> gave xyyz,
> and the idiom to put ]]> in CDATA followed by a new line
> (<![CDATA[a]]]]><![CDATA[>b]]>) gave a]]>b>b. With a comment in between it
> failed with ArrayIndexOutOfBoundsException. The parser joined the first
> section into its buffer when it read the second one, but still marked it as
> to be joined, so the following text joined it again. This is from the
> original xpp3 code.
> # *A character reference above U+FFFF is silently truncated.* 😀 gave
> U+F600 instead of the emoji, as the code point was kept in a char. A
> reference that is not a valid character now fails.
> # *dumpBeansAsXml produces malformed XML.* The <script> of a bean was written
> inside its start tag, and no value was escaped, so a property value such as a
> url with & gave invalid XML (also in camel-xml-jaxb, which has a copy of that
> code). A bean without a type failed with NullPointerException.
> # *The XML and YAML dumpers drop the note of the routes and EIPs* (added in
> CAMEL-22576), as their override of the id/description attributes did not
> write it.
> # *An encoding declared on another line of the XML declaration is ignored.*
> <?xml version="1.0"\n encoding="ISO-8859-1"?> was read as UTF-8 (so café was
> read wrongly), as the pattern did not match across lines.
> *Not changed (for a later look)*
> * Whitespace-only expression text is dropped even with trim="false".
> * Each dump and re-parse cycle adds another copy of the xpath namespace.
> * An error for an invalid attribute points at the end of the start tag, not
> where it starts.
> * With CR-only line endings every line number is 1.
> * A UTF-8 BOM that disagrees with the declared encoding: the declaration wins.
