地图合并的BaseX XQuery问题？

编程问答 2022-08-13

问题描述

我想在BaseX上使用XQuery（当前使用BaseX v9.4.1）将CSV转换为XML。 CSV文件Configuration.tsv（输入）与“列”标签分开时，如下所示：

Datasets    Autosar             Fibex           TSS0001  TSS0002  TSS0003
DS0001      AutosarFoo01.arxml  FibexFoo01.xml  x        x  
DS0002      AutosarFoo02.arxml  FibexFoo02.xml  x                 x
DS0003      AutosarFoo03.arxml  FibexFoo03.xml  x                 x

脚本以tssid作为输入参数。设置tssid := TSS0001 XML 期望 输出是：

<database name="DS0001" autosar="AutosarFoo01.arxml" fibex="FibexFoo01.arxml"/>
<database name="DS0002" autosar="AutosarFoo02.arxml" fibex="FibexFoo02.arxml"/>
<database name="DS0003" autosar="AutosarFoo03.arxml" fibex="FibexFoo03.arxml"/>

并带有tssid := TSS0003：

<database name="DS0002" autosar="AutosarFoo02.arxml" fibex="FibexFoo02.arxml"/>
<database name="DS0003" autosar="AutosarFoo03.arxml" fibex="FibexFoo03.arxml"/>

该脚本可以正常工作，但是缺少第三个属性值（fibex），因此输出看起来像这样：

<database name="DS0001" autosar="AutosarFoo01.arxml" fibex=""/>
<database name="DS0002" autosar="AutosarFoo02.arxml" fibex=""/>
<database name="DS0003" autosar="AutosarFoo03.arxml" fibex=""/>

或使用tssid := TSS0003：

<database name="DS0002" autosar="AutosarFoo02.arxml" fibex=""/>
<database name="DS0003" autosar="AutosarFoo03.arxml" fibex=""/>

我找不到此代码有问题吗？！？ ：

xquery version "3.1" encoding "utf-8";

declare namespace test="unittest";

declare namespace map="http://www.w3.org/2005/xpath-functions/map";

declare variable $test:tssid := 'TSS0003';

declare variable $test:testsuitesfile := '/Users/ms/Projekte/UnitTests/Configuration.tsv';

declare variable $test:options := map { 'header' : 'yes','format' : 'attributes','separator' : 'tab' };

declare variable $test:xml := csv:doc($test:testsuitesfile,$test:options);

(: get the positions :)

declare variable $test:positionDataId := 1 ;

declare variable $test:positionTssCheck := $test:xml/csv/record[position() = 1]/entry[text() = $test:tssid]/count(./preceding-sibling::entry) + 1 ;

declare variable $test:positionAutosar := $test:xml/csv/record[position() = 1]/entry[text() = 'Autosar']/count(./preceding-sibling::entry) + 1 ;

declare variable $test:positionFibex := $test:xml/csv/record[position() = 1]/entry[text() = 'Fibex']/count(./preceding-sibling::entry) + 1 ;

declare variable $test:dbsetbycsv as map(*) := map:merge(for $record in $test:xml/csv/record[entry[position() = $test:positionTssCheck and text()='x']] return map:entry($record/entry[position() = $test:positionDataId]/text(),<database name="{$record/entry[position() = $test:positionDataId]/text()}" autosar="{$record/entry[position() = $test:positionAutosar]/text()}" fibex="{$record/entry[position() = $test:positionFibex]/text()}"/>));

declare variable $test:dbset := $test:dbsetbycsv;

declare function test:dump() {
  for-each(
    map:keys($test:dbset),function($k) { 
      $test:dbset($k)
    }
  )
};

let $result := test:dump()

return($result)

解决方法

这是一个错误。现在已通过BaseX 9.4.3 Beta修复。

,

似乎

$xml/csv/record[entry[@name = $tssid and . = 'x']] ! <database name="{entry[@name = 'Datasets']}" autosar="{entry[@name = 'Autosar']}" fibex="{entry[@name = 'Fibex']}"/>

只要entry元素具有name属性，就足够了。
