C# XmlDocument: Dynamically retrieve xml childnode attribute names-CodePudding

I have the following sample XML-file:

<response location='location1'>
    <meas name='mt1'>14</meas>
    <meas name='mt2'>23</meas>
    <meas name='mt3'>65</meas>
    <meas name='mt4'>31</meas>
    <meas name='mt6'>32</meas>
</response>

I can retrieve the inner values, but I am trying to also dynamically retrieve "name" value of each childnode, ie: 'mt1', 'mt2', etc.

How would one go about doing this in XmlDocument?

CodePudding user response：

Given the XML structure provided and an XmlDocument, query for the meas nodes and then get the attribute values:

static string xml = @"<response location='location1'>
    <meas name='mt1'>14</meas>
    <meas name='mt2'>23</meas>
    <meas name='mt3'>65</meas>
    <meas name='mt4'>31</meas>
    <meas name='mt6'>32</meas>
</response>";

var doc = new XmlDocument();
doc.LoadXml(xml);

var nodes = doc.SelectNodes("//response/meas");
foreach (XmlElement e in nodes)
{
    Console.WriteLine(e.GetAttribute("name"));
}

Result:

mt1
mt2
mt3
mt4
mt6

Alternatively, directly query the attributes:

var attrs = doc.SelectNodes("//response/meas/@name");
foreach (XmlAttribute e in attrs)
{
    Console.WriteLine(e.Value);
}
