ANN: xmlwrapp 0.8.0

[Vadim Zeitlin]

Hello,

We've finally made a new xmlwrapp release, accumulating a few changes
since the last 3+ years. The new release is available from

https://github.com/vslavik/xmlwrapp/releases/tag/v0.8.0

The most important change in this release is the improved error handling:

- New behaviour: xml::document::save_to_{string,file}() now throws
exception in case of failure by default instead of silently ignoring any
errors.
- New behaviour: xpath_context::evaluate() also throws an exception if an
invalid XPath expression is specified.

In both cases, ignore_errors can be passed as the new on_error argument to
these functions to restore the old behaviour (this is, however, not
recommended).

There also some new features:

- Added xml::node::move_under().
- Added xml::node::set_namespace().
- Added xml::xpath_context class for evaluating XPath expressions.
- Added xml::nodes_view::erase() analogous to node::erase().


We hope you will find this new version useful,
VZ
