-----------------------------------
Summary: The HTL parser can get confused when HTML markup is
present in string literals
Key: SLING-12325
URL: https://issues.apache.org/jira/browse/SLING-12325
Project: Sling
Issue Type: Bug
Components: HTL
Reporter: Csaba Varga
In some cases, HTL that's perfectly valid based on the spec will cause a
compilation error. For example, this will be rejected when used outside of an
attribute:
{code:java}
${'<a href="{0}">Click here</a>.' @ format='/', context='html'} {code}
The HTML parsing phase will consider the first closing brace to be the end of
the expression, and the </a> part as a tag outside of an expression. The next
phase will see this expression:
{code:java}
${'<a href="{0}">Click here {code}
and reject it as syntactically invalid.
The HTML parsing phase needs to be more careful about expression syntax. I
think it will need to look out for quotes and backslashes to safely tell
whether a closing brace is an expression terminator or just a regular character
inside a string literal.
