xmlstarlet 使用子节点提取组信息

Question

我需要从复杂的 XML 文件中提取组信息，然后遍历组以执行一些更改，但我无法以干净的方式循环获取数据。尝试了很多，看到了很多例子，但没有运气。任何帮助表示赞赏。

给定以下 XML 文件：

<?xml version='1.0' encoding='UTF-8'?>
<tsResponse xmlns="http://tableau.com/api" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://tableau.com/api http://tableau.com/api/ts-api-3.12.xsd">
    <pagination pageNumber="1" pageSize="100" totalAvailable="12"/>
    <groups>
        <group id="74c29008-7550-11eb-94d7-73020b27aff3" name="Todos os usuários">
            <domain name="local"/>
        </group>
        <group id="e392c24a-535d-4e78-8463-0a492d61c317" name="Tbv_Vs_Operacoes">
            <domain name="university.net"/>
            <import domainName="university.net" siteRole="Viewer" grantLicenseMode="onLogin"/>
        </group>
        <group id="6c236376-aa1b-451e-8b63-488387aac20b" name="Tbv_Alertas_Inteligentes">
            <domain name="university.net"/>
            <import domainName="university.net" siteRole="Viewer" grantLicenseMode="onLogin"/>
        </group>

        </group>

            <import domainName="university.net" siteRole="Viewer" grantLicenseMode="onSync"/>
        </group>

            <domain name="university.net"/>
            <import domainName="university.net" siteRole="Explorer" grantLicenseMode="onSync"/>
        </group>
    </groups>
</tsResponse>

如何获得如下 csv 的输出，每组一行 4 列：id、name、siteRole 和 grantlicenseMode？​​p>

我设法使用以下命令输出“组”节点内的值：

xmlstarlet sel -N api=http://tableau.com/api -T -t -m //api:group -v "concat(@id,';',@name,';',import/@siteRole,';',import/@grantLicenseMode)" -n groups.xml

但正如您在上面看到的，我无法获得@siteRole 和@grantLicenseMode 的值，它们都在子节点“import”上。

Answer 1

我建议：

xmlstarlet select -N x="http://tableau.com/api" --text --template \
  --match "//x:tsResponse/x:groups/x:group" \
  --value-of "concat(@id,',',@name,',',x:import/@siteRole,',',x:import/@grantLicenseMode)" \
  -n file.xml

输出：

74c29008-7550-11eb-94d7-73020b27aff3,Todos os usuários,,
e392c24a-535d-4e78-8463-0a492d61c317,Tbv_Vs_Operacoes,Viewer,onLogin

89c33fb6-dce9-4097-9be8-f01d502cc11b,Tbl_Server_Admin_Creator,SiteAdministratorExplorer,onLogin
