OpenDaylight JIRA https://jira.opendaylight.org This file is an XML representation of an issue en-us 8.20.10 820010 22-06-2022 [YANGTOOLS-877] Add yang-model-api model of an XPath expression https://jira.opendaylight.org/browse/YANGTOOLS-877 yangtools <p>Current RevisionAwareXPath is quite deficient in expressing the XPath stored therein. More specifically it requires anyone attempting to use it infer the prefix/namespace mapping and then parse the expression itself.</p> <p>Instead of going through these hoops, we really should have an object model of the expression, similar to org.jaxen.expr.Expr, which would act as an intermediate representation format, where all prefixes would already be properly resolved so that we are dealing with QNames instead of prefix+localnames.</p> <p>The parser should also bind function invocations for YANG-defined functions, so that their arguments are resolved to proper types.</p> YANGTOOLS-877 Add yang-model-api model of an XPath expression New Feature Medium Resolved Done Robert Varga Robert Varga Wed, 2 May 2018 11:03:11 +0000 Thu, 2 Aug 2018 08:51:12 +0000 Thu, 2 Aug 2018 08:51:12 +0000 2.0.10 parser 0 1 <p>Note that this layer of XPath model needs to provide for predicates for node lookups, unlike <a href="https://jira.opendaylight.org/browse/YANGTOOLS-878" title="Add yang-data-api model of an XPath expression" class="issue-link" data-issue-key="YANGTOOLS-878">YANGTOOLS-878</a>, which should further extend the model to resolve them to PathArgument lookups.</p> <p>The possibility of binding expression (literals, identity references, etc.) to Java types should be evaluated – it needs to happen in places where we can statically infer the type and should happen either in scope of this issue or in <a href="https://jira.opendaylight.org/browse/YANGTOOLS-878" title="Add yang-data-api model of an XPath expression" class="issue-link" data-issue-key="YANGTOOLS-878">YANGTOOLS-878</a>. It is okay to have a partial type binding, as the XPath evaluation engine needs to be able to cope with both.</p> <p>This is still missing an implementation.</p> Blocks YANGTOOLS-878 Development Rank 0|i03e3z:
