Re: [Exist-development] Getting lots of optimizer warnings in log....

[Jens Ø. P. <oe...@gm...>]

Hi Andrzej,

I had a number of these, but but they were easy enough to get rid of. 

An expression like

if ($placeTerm[@type = 'text'])

caused the error in the beginning of

28 Apr 2011 08:47:39,084 [eXistThread-192] WARN  (Optimizer.java [visitFilteredExpr]:133) - Parent expression of step is not a PathExpr: if ( $placeTerm[attribute::type = "text"] ) then concat(atomize[dynamic-cardinality-check("zero or one", $placeTerm[attribute::transliteration]/child::text())], dynamic-cardinality-check("zero or one", " "), atomize[dynamic-cardinality-check("zero or one", $placeTerm[not(dynamic-cardinality-check("zero or more", attribute::transliteration))]/child::text())]) else if ( $placeTerm[attribute::authority = "marccountry"]/child::text() ) then doc(dynamic-cardinality-check("zero or one", concat(dynamic-cardinality-check("zero or one", $config:edit-app-root), dynamic-cardinality-check("zero or one", "/code-tables/marc-country-codes.xml"))))/child::code-table/child::items/child::item[child::value = $placeTerm]/child::label else if ( $placeTerm[attribute::authority = "iso3166"]/child::text() ) then doc(dynamic-cardinality-check("zero or one", concat(dynamic-cardinality-check("zero or one", $config:edit-app-root), dynamic-cardinality-check("zero or one", "/code-tables/iso3166-country-codes.xml"))))/child::code-table/child::items/child::item[child::value = $placeTerm]/child::label else $place/child::mods:placeTerm[not(dynamic-cardinality-check("zero or more", attribute::type))]/child::text() 

whereas no error is generated with

if ($placeTerm[@type = 'text']/text())

In your case, it would occur when you set one of your variables.

To me it looks like one is warned if a path expression does not end in a node. - Isn't this good?

Best,

Jens
