使用xmlstarlet将xml递归循环到csv

我想将复杂的xml转换为csv

<tests>
    <test>
        <name>AAA</name> 
        <language>BBB</language> 
        <Project>
            <name>XXX</name>
            <id>123</id>
        </Project>
        <fac>
            <name>XXX</name>
            <idt>
                <number>99</number>
            <idt>
            <pers>YYY</pers>
        </fac>
        <fac>
            <name>BBB</name>
            <idt>
                <number>70</number>
            <idt>
            <pers>MMM</pers>
        </fac>
        <fac>
            <name>XXX</name>
            <idt>
                <number>40</number>
            <idt>
            <pers>XXX</pers>
        </fac>
        <date>2018</date>
    </test>
    <test>
    <name>BBB</name> 
    <language>CCC</language> 
    <Project>
        <name>AAA</name>
        <id>12</id>
    </Project>
    <fac>
        <name>YXX</name>
        <idt>
            <number>10</number>
        <idt>
        <pers>LLL</pers>
    </fac>
    <fac>
        <name>BB</name>
        <idt>
            <number>7</number>
        <idt>
        <pers>MM</pers>
    </fac>
    <fac>
        <name>XX</name>
        <idt>
            <number>40</number>
        <idt>
        <pers>XXX</pers>
    </fac>
    <date>2018</date>
</test>
 <tests> 

一切正常，但我只能获取第一个节点中包含的数据。我想要的是这样的东西：

第一次

    name;language;name;id;data contained in the first node"fac";date 
    name(same as first line);language(same as first line); etc..; data contained in the second "fac" node;date (same as first line)
etc... as much as there are face nodes

然后是第二个节点

我不知道是否可以使用xmlstarlet实现这一点

提前感谢您的帮助

尝试以下xml linq：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;
using System.IO;

namespace ConsoleApplication1
{
    class Program
    {
        const string XML_FILENAME = @"c:\temp\test.xml";
        const string CSV_FILENAME = @"c:\temp\test.csv";
        static void Main(string[] args)
        {
            string[] headers = {
                                   "test name",
                                   "language", 
                                   "project name",
                                   "project id",
                                   "fac name",
                                   "idt number",
                                   "pers"
                               };
            StreamWriter writer = new StreamWriter(CSV_FILENAME);
            writer.WriteLine(string.Join(",", headers));

            XDocument doc = XDocument.Load(XML_FILENAME);

            foreach (XElement test in doc.Descendants("test"))
            {
                string testName = (string)test.Element("name");
                string language = (string)test.Element("language");

                XElement project = test.Element("Project");
                string projectName = (string)project.Element("name");
                string projectId = (string)project.Element("id");

                foreach(XElement fac in test.Elements("fac"))
                {
                    string facName = (string)fac.Element("name");
                    string number = (string)fac.Descendants("number").FirstOrDefault();
                    string pers = (string)fac.Element("pers");

                    string csvLine = string.Join(",", new string[] {
                        testName,
                        language,
                        projectName,
                        projectId,
                        facName,
                        number,
                        pers
                    });
                    writer.WriteLine(csvLine);
                }
            }


            writer.Flush();
            writer.Close();
        }
    }
}

如果您希望为每个

fac

输入一个条目，则应匹配该条目。然后，您可以转到祖先

测试

，以获取所需的其他数据

例如

xmlstarlet sel -T -t -m "//fac" -v "concat(ancestor::test/name,';',ancestor::test/language,';',ancestor::test/Project/name,';',ancestor::test/Project/id,';',name,';',idt/number,';',pers,';',ancestor::test/date)" -n test.xml

输出

AAA;BBB;XXX;123;XXX;99;YYY;2018
AAA;BBB;XXX;123;BBB;70;MMM;2018
AAA;BBB;XXX;123;XXX;40;XXX;2018
BBB;CCC;AAA;12;YXX;10;LLL;2018
BBB;CCC;AAA;12;BB;7;MM;2018
BBB;CCC;AAA;12;XX;40;XXX;2018

下面是为便于阅读而细分的

concat（）

concat(
    ancestor::test/name,';',
    ancestor::test/language,';',
    ancestor::test/Project/name,';',
    ancestor::test/Project/id,';',
    name,';',
    idt/number,';',
    pers,';',
    ancestor::test/date
)

您的示例输入不是有效的XML，看起来您的所有

都已转换为

？修复后，您的

xmlstarlet

调用对我来说很好。谢谢，我的xml不是这样的，但在这个示例中我忘记了它。即使我改变了它，我也会得到第一个吗？我得到两行输出：

AAA；BBB；XXX；123;XXX；99;YYY；2018年

之后是

BBB；CCC；AAA；12;YXX；10;LLL；2018年

。我现在不知道如果我很清楚，我想要的是第一个节点：

AAA；BBB；XXX；123;XXX；99;YYY；2018年

then

AAA；BBB；XXX；123;BBB；70;嗯,；2018年

then

AAA；BBB；XXX；123;XXX；40;XXX；2018

第二个节点也一样。@DanielHaley感谢您的帮助。现在一切都好了：）谢谢，我也要试试。

concat(
    ancestor::test/name,';',
    ancestor::test/language,';',
    ancestor::test/Project/name,';',
    ancestor::test/Project/id,';',
    name,';',
    idt/number,';',
    pers,';',
    ancestor::test/date
)
