BaseX

问题 While the JSON is correctly formatted (the jsonTweet variable): The JSON input is valid according to RFC 4627 (JSON specfication). Close The JSON input is valid in JavaScript. However, the xml output is obviously invalid (as xmlStringTweet isn't xml at all). The key lines, as it were: JSONObject jsonTweet = tweets.getJSONObject(Long.toString(id)); xmlStringTweet = XML.toString(jsonTweet); where the jsonTweet is found by the "snowflake" id, and, then, ostensibly, converted to an xml string.

问题 This one-liner in powershell achieves the purpose of converting JSON from Twitter to XML , albeit probably formatted differently: $tweets = Get-Content 'tweets.json' | Out-String | ConvertFrom-Json | Export-Clixml "./tweets.xml" Also, certainly it's easy enough to create an XML document from a JSON file using org.json below: package basex; import java.io.IOException; import java.nio.charset.StandardCharsets; import java.nio.file.Files; import java.nio.file.Paths; import java.util.logging

问题 In order to build a JSONArray , how is data from BaseX exported as JSON ? Or queried with XQuery so that the String can be read with Java. Output as: [ { "0":"z10", "1":"y9", "2":"x7", "3":"atrib6", "name":"alice" }, { "0":"home5", "1":"cell4", "name":"sue" }, { "0":"phone3", "1":"phone2", "2":"phone1", "name":"joe" }, { "name":"people" } ] How would loadPeople perform the inverse operation of addPeople ? There must be an input of String to addPeople . Where addPeople takes a JSONArray and

问题 How is a JSONObject from Twitter4J converted to an IOFile for use with the JsonParser from BaseX ? So, looking to use Twitter4J to get either a file or stream. The JsonParser looks to work with a File fine: JsonParser public JsonParser(IO source, MainOptions opts, JsonParserOptions jopts) throws java.io.IOException Constructor. Parameters: source - document source opts - database options jopts - parser options Throws: java.io.IOException - I/O exception although other IO works: org.basex.io

问题 I would like to extract the XPATH //DIV[@id="ps-content"] out from this web page: http://www.amazon.com/dp/1449319432 (saved as a local file) I would like to do it with a single line of command-line with one of the best parsers, like Saxon-PE or BaseX. So far the shortest solution that I (seemed to have) found is with these two lines: java -jar tagsoup-1.2.1.jar <page.html >page.xhtml" java -cp saxon9pe.jar net.sf.saxon.Query -s:"page.xhtml" -qs:"//DIV[@id='ps-content']" but all what it

问题 I'm using BaseX as my XML based DB. I make a simple query like xquery for $Book in /Libraray/Literaturelist/Literature/Title return fn:data($Book) I get all titles, just as a String that has got no line breaks. Is there a way to add line-breaks with XQuery after each node found by the query to separate the data? This is not really dependant on my XML file because I do not add line-breaks hardcoded within the tags. ;) 回答1: it depends on how you retrieve the query results. The most elegant way
