exist-db

I'd like to remove all NULL characters from the string. I know that the right regex match should be \x00 and I've tried the following XQuery: replace($message, '\x00', '') It results in the error: exerr:ERROR Conversion from XPath2 to Java regular expression syntax failed: Error at character 1 in regular expression \x00: invalid escape sequence Is there any quick solution or workaround for this issue? I use eXist-db 2.2. Jens Erat The short version: you can't, at least not within the boundaries of the XQuery and XML specifications. There may be an eXist-DB-proprietary method I am not aware of

I have an XQuery function to convert a group of XML files to HTML and Zip them. It runs a trasform on each file to create <entry> elements. Starting with that function: declare function xport:make-sources( $path as xs:string) as item()* { for $article in collection(xmldb:encode-uri($path)) let $docnum := $article/article/div[@class = 'content']/@doc/string() return <entry name="{concat($docnum,'.html')}" type='text' method='store'> {transform:transform($article, doc("/db/EIDO/data/edit/xsl/doc-html.xsl"), <parameters/>)} </entry> } ; Given the input, I run the XQuery to just show me the result
