xquery

问题 I want to insert a node using below code but if i will rerun the code i don't want my node to be repeated twice if all the elements are having same value- let $doc := fn:doc("abc.xml") (: abc.xml looks like-- <root> <value1>somevalue</value1> <value2>somevalue</value2> <value3>somevalue</value3> <value4>somevalue</value4> <Country>Australia</Country> <value6>somevalue</value6> <value7>somevalue</value7> <value8>somevalue</value8> <value9>somevalue</value9> <value10>somevalue</value10> </root>

问题 With Xquery I want to get the row which has the min sortOrder. In the example below the row with id=3. <table> <row id="1"><attribute identifier="sortOrder">120</attribute><attribute identifier="mainContent">Test 3</attribute></row> <row id="2"><attribute identifier="sortOrder">130</attribute><attribute identifier="mainContent">Test 1</attribute></row> <row id="3"><attribute identifier="sortOrder">10</attribute><attribute identifier="mainContent">Test 2</attribute></row> </table> Anyone got a

问题 I've got a BaseX XML database with ~20 XML files. These files are different in size and structure. The biggest file has got 524 MB. It consists of a parent ARTICLE tag with 267685 ART subtags. This is my XQuery: "/ARTICLE/ART[PRDNO=12345]" (pretty straightforward; proper namespaces omitted for clarity). PRDNO is a foreign key to the PRODUCT/PRD XML structure, there are multiple (in average ~10) products per article. Everything works as it is supposed to, but this query is quite slow - it

问题 There is a question somewhere on Stackoverflow, although i cannot find it now, that reminded the poster that .value does not return the value that .exist s. That is because .value is always written as asking for the [1] item, where .exist looks everywhere. Example Given a hypothetical xml document containing two customers: <Customer> <Name>Ian Boyd</Name> <IDInfo> <IDType>1</IDType> </IDInfo> </Customer> <Customer> <Name>Kirsten</Name> <IDInfo> <IDType>3</IDType> <IDOtherDescription>Firearms

问题 I want to figure out one issue. I already had question about simple ordering issue but I want to order more detail. check below this link : SQL Server : FOR XML sorting control by attribute I made a example case. SQL Query. select ( select '123' AS '@id', ( select ( select 'test' AS '@testid' , '20' AS '@order' FOR XML path ('tree') , TYPE ), ( select 'test2' AS '@testid' , '30' AS '@order' FOR XML path ('tree-order') , TYPE ), ( select 'test' AS '@testid' , '10' AS '@order' FOR XML path (

问题 I am trying this in an XQuery (assume that doc('input:instance') does indeed return a valid XML document) which is generated using XSLT let $a:= <xsl:text>"<xsl:copy-of select="doc('input:instance')//A" />"</xsl:text> let $p := <xsl:text>"<xsl:copy-of select="doc('input:instance')//P" />"</xsl:text> let $r := <xsl:text>"<xsl:copy-of select="doc('input:instance')//R" />"</xsl:text> But I get the error: xsl:text must not contain child elements How do I retrieve XML results using the XPath in

问题 Edit: See This link for follow-up question I have a large FOR XML EXPLICIT query in SQL Server 2008 R2 that creates an xml file, but it is failing to validate against my XSD schema because some of the mid-level elements appear in the wrong order. Here is an example XML file to show what I mean: <Things> <Thing> <Racecars> <Racecar> <Colour>Red</Colour> <Rockets>Y</Rockets> </Racecar> <Racecar> <Colour>Blue</Colour> <Rockets>N</Rockets> </Racecar> </Racecars> </Thing> <Thing> <Numbers> <Number

问题 I have a table in SQL server that is used to store submitted form data. The form fields for each submission are dynamic so the collected data is stored as name value pairs in an XML data column called [formdata] as in the example below... This works fine for collecting the required information but I now need to render this data to a flat file or an excel document for processing by human staff members and im wondering what the best way of doing this would be using Xquery so that the data is

问题 There are 2 collections /test/123 and test/567 I want to return the latest document of both the collections. let $a := cts:collection-match("/test/*") for $t in $ a let $latest :=( for $doc in fn:collection( $t) order by $doc//timestamp descending return $doc)[1] return fn:concat($latest//id/text(),",",$latest//timestamp/text()) Is there a better to get the latest document from the collections I want the final output of query after searching both the collection to be in descending order for
