使用Groovy将xml转换为csv

Question

我正在尝试使用groovy XmlSlurper().parseText()将以下XML转换为CSV，但是移动到内部节点时什么都不会打印。

Xml文件：

 string input = """<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<executeQueryInSpaceResponse>
    <executeQueryInSpaceResult>
        <rows>
            <ArrayOfString>

Groovy代码：

content = new XmlSlurper().parseText(input)
println content
println content.executeQueryInSpaceResponse.executeQueryInSpaceResult

它没有打印任何内容。预期的输出将是这样，

预期的输出CSV文件：

csv文件的标头应为：

Name,First Name,Last Name,Address Line 1,Address Line 2,City,State,Country,Postal Code,Program,Campus Name,Date ASP,Date LEGACY,Success 1,Success 2,Received Date,Submitted Date,Complete Date,Decision Date,Registration Date,FDOC Date,Status,Step,LeadId,Source,Vendor,Client,SAVEDEXPRESSION

行应该是

ABCDEF,ABC,DEF,Shilo,,August,Georgia,,34566,Studies,August,,,Clerk,,2016-01-05 00:00:00.000,,,,,,Not Qualified,Unintended Request,512544989,marketing,Interactive,,0
ABCDEF,ABC,DEF,Shilo,,August,Georgia,,34566,Studies,August,,,Clerk,,2016-01-05 00:00:00.000,,,,,,Not Qualified,Unintended Request,512544989,marketing,Interactive,,0

Answer 1

您在代码中放入的行将返回xml的root节点。

content = new XmlSlurper().parseText(input)

如果您输入content.executeQueryInSpaceResponse，则不会返回任何内容。因为content是您的根节点executeQueryInSpaceResponse。两者都一样。

您需要替换如下所示的代码：

println content.executeQueryInSpaceResult

，我也建议您参考Groovy-XML Parsing。享受编码！

Answer 2

以下是可帮助您的代码段：

def header = content.executeQueryInSpaceResult.columnNames.children().collect().join(',')
def csv = content.executeQueryInSpaceResult.rows.children().inject(header){ result, row ->
 [result, row.children().collect().join(',')].join("\n")
}
