XPath20ExpressionCompilerImpl can't parse functions with embedded functions
---------------------------------------------------------------------------
Key: ODE-840
URL: https://issues.apache.org/jira/browse/ODE-840
Project: ODE
Issue Type: Bug
Components: BPEL Compilation/Parsing
Affects Versions: 1.3.4
Environment: ODE 1.3.4 ReleaseCandidate
Reporter: Mateusz Nowakowski
Fix For: 1.3.4
org.apache.ode.bpel.elang.xpath20.compiler.XPath20ExpressionCompilerImpl.doJaxpCompile(OXPath20ExpressionBPEL20
out, Expression source):Line 169-170
for (String functionExpr : extractFunctionExprs(xpathStr)) {
expr = xpe.compile(functionExpr); //Line: 170 here an exception
is thrown
try {
expr.evaluate(node);
} catch (XPathExpressionException xpee) {
// swallow errors caused by uninitialized variable
}
}
xpathStr equals:
bpel:doXslTransform("1.0.1/some.xsl", $Variable.body, "someParameter",
$OtherVariable.body, "someParameter2", $SwsHeaderRQ, "someParameter3", true(),
"someXpathParameter", $XPath)
The result of extractFunctionExprs(xpathStr) is a list with one element:
bpel:doXslTransform("1.0.1/some.xsl", $Variable.body, "someParameter",
$OtherVariable.body, "someParameter2", $SwsHeaderRQ, "someParameter3", true()
but it should be the same as xpathStr.
So the results is that Line 170 throws an exception:
Caused by: net.sf.saxon.trans.XPathException: XPath syntax error at char 149 in
{...derRQ, "someParameter3", tru...}:
expected ")", found "<eof>"
