Hi Stewart, I am not quite sure why, but I think this has to do with the way the PI is constructed, where it does not want any whitespace in it.
Here is a way around the issue by first constructing a string and then creating an XML node out of it: let $xml-version := '<?xml version="1.0" encoding="UTF-8"?>' let $stylesheet := "<?xml-stylesheet type='text/xsl' href='http://ldschurch.dataformat.com/local/PMDC_TEISchema_Normal.xsl'?>" let $tei := '<teiCorpus>hello</teiCorpus>' return (xdmp:unquote(fn:concat($xml-version,$stylesheet, $tei))) If the node is already in the database, another way is to use xdmp:node-insert-*, as follows: let $pi := <?xml-stylesheet type='text/xsl' href='http://ldschurch.dataformat.com/local/PMDC_TEISchema_Normal.xsl'?> return xdmp:node-insert-before(doc("Docs/test.xml")/my-root, $pi) Not sure if that will help but it might get you past it. -Danny From: [email protected] [mailto:[email protected]] On Behalf Of Stewart Shelline Sent: Wednesday, June 10, 2009 11:37 AM To: General Mark Logic Developer Discussion Subject: [MarkLogic Dev General] Adding processing instructions to the document node I need to be able to add processing instructions to documents I create and store in ML. I assumed the following would accomplish that: let $xml-version := <?xml version="1.0" encoding="UTF-8"?> let $stylesheet := <?xml-stylesheet type='text/xsl' href='http://ldschurch.dataformat.com/local/PMDC_TEISchema_Normal.xsl'?> let $tei := <teiCorpus ...>...</teiCorpus> return xdmp:document-insert( $uri, ($xml-version,$stylesheet,$tei) ) However, this throws the following error: XDMP-XMLPI: (err:XPST0003) <?xml version="1.0" encoding="UTF-8"?> -- Processing instructions may not have the target 'XML' Sorry for the newbie question, but what am I missing here?
