Hi, When serializing XML to CSV, special characters (e.g., &) are not converted to their textual representations (e.g., ‘&’). For example, the code below outputs conditionid nctid condition 1 NCT00130377 Cardiovascular System Diseases (& [Cardiac]) vs. the expected conditionid nctid condition 1 NCT00130377 Cardiovascular System Diseases (& [Cardiac]) This seems like a bug. Am I missing an option? I did not see anything related in the documentation. Thanks, Ron let $options := map { 'lax': false(), 'quotes' : false(), 'separator' : 'tab', 'header' : true() } return file:write('conditions.tsv', csv:serialize( <matches> { for $article in db:open('CTGov')/clinical_study where $article//nct_id = 'NCT00130377' for $condition in $article/condition count $c return <match> <conditionid> { $c } </conditionid>, <nctid> { normalize-space($article/id_info/nct_id/text()) } </nctid>, <condition> { normalize-space($condition/text()) } </condition> </match> } </matches>, $options) )
