The latest spec for what it essentially an XPath extension seems to be
this working draft from 2002:
https://www.w3.org/TR/xptr-xpointer/
The xpointer() scheme is listed as "being reviewed" in the XPointer
registry since at least 2006. libxml2 seems to be the only modern
software that tries to implement this spec, but the code has many bugs
and quality issues.
If you configure --with-legacy, old symbols are retained for ABI
compatibility.
- xmlInputCreateUrl
- xmlInputCreateMemory
- xmlInputCreateString
- xmlInputCreateFd
- xmlInputCreateIO
- xmlInputSetEncoding
These functions don't take a parser context and work on xmlParserInputs,
replacing functions working on xmlParserInputBuffers.
xmlInputCreateUrl and xmlInputSetEncoding offer fine-grained error
handling.
Several XML_INPUT_* flags offer additional control.
This is a useful function to get a verbose error report.
Allows to remove duplicated code from runtest.c. Also reactivate check
for schema parser failures.
Deeply nested documents can cause performance problems, so the nesting
depth should always be limited to a reasonable value.
Also remove the global xmlParserMaxDepth setting which isn't thread-safe
and seems unused.
Surprisingly, some options can only be enabled with xmlCtxtUseOptions
and it's impossible to unset them. Add a new API function
xmlCtxtSetOptions which sets or clears all options.
Finally document all parser options.
Make sure to synchronize option bits and struct members.
Provide a new set of functions to create xmlParserInputs. These can be
used for the document entity or from external entity loaders.
- Don't require xmlParserInputBuffer.
- All functions take a base URI.
- All functions take an encoding as string.
- xmlNewInputURL also takes a public ID.
- xmlNewInputMemory takes a size_t.
- Optimization hints for memory buffers.
Improve documentation.
Only call xmlInitParser before allocating a new parser context.
Call xmlCtxtUseOptions as early as possible.
Make sure that references from IDs are updated.
Note that if there are IDs with the same value in a document, the last
one will now be returned. IDs should be unique, but maybe this should be
addressed.
