Search Confg.xml

[Ron22]

Remember I am new to C# and .net program so be nice
How would I search the config.xml passed to the plugin for a partial string? I want to search for “MAC-“
I am currently using
XmlNode node = doc.SelectSingleNode("/settings/MVPWidth")
to read in the sections I want.
Currently the only thing I can think of is using NextSibling and stepping through the file and comparing them. Is there an easier way?

XmlNode node = doc.SelectSingleNode("/settings/MVPWidth")

Are you trying to get all the MVPWidths regardless of MAC address, if so, you might be able to do something likeL

/settings/*/MVPWidth

Which would return you a Nodeset of all the MVPWidth elements. You could then use the ParentNode function to get the element's name that that particular element belongs to.

Personally, if you are wanting the name of the name of each MAC address that is specified, you might be able to use a combination of the XPath name() function and the node() functions.

Something like the following might get you the name, but I haven't tested this:

/settings/*/MCPWidth[contains(name(parent), 'MAC')]


Personally, I'd like to see a bit of redesign for the config XML file when it comes to storing the MAC addresses. Something like the following:

Code:

<settings>
    <MVP>
        <MACSettings>
               <Address>MAC-000DFEE029B2</Address>
               <MVPWidth>600</MVPWidth>
               <MVPHeight>400</MVPHeight>
               <MVPOffsetX>44</MVPOffsetX>
               <MVPOffsetY>50</MVPOffsetY>
       </MACSettings>
    </MVP>
</settings>

A list of the various XPath functions can be found here:

What I am trying to do is get each MAC-000DFEE029B2 listing. Then for my plugin I can automatically pull in all the current MAC address in the config.xml file.

I think I understand what you want. Consider the following code:

Code:

string x = "<config>"
    +  "<MAC-000DFEE029B2><MVPWidth>600</MVPWidth><MVPHeight>400</MVPHeight><MVPOffsetX>44</MVPOffsetX><MVPOffsetY>50</MVPOffsetY></MAC-000DFEE029B2>"
    +  "<MAC-0223333B2><MVPWidth>600</MVPWidth><MVPHeight>400</MVPHeight><MVPOffsetX>44</MVPOffsetX><MVPOffsetY>50</MVPOffsetY></MAC-0223333B2>"
    +  "<MAC-abcde><MVPWidth>600</MVPWidth><MVPHeight>400</MVPHeight><MVPOffsetX>44</MVPOffsetX><MVPOffsetY>50</MVPOffsetY></MAC-abcde>"
    +  "</config>";

System.Xml.XmlDocument xml = new System.Xml.XmlDocument();
xml.LoadXml(x);

System.Xml.XmlNodeList nl= xml.SelectNodes("//MVPWidth/..");

foreach (System.Xml.XmlNode n in nl)
    Console.WriteLine(n.Name);

Console.ReadLine();

What's important here is the XPath of: "//MVPWidth/.."

This will return a nodeset of all parent nodes that have a MVPWidth child anywhere in the document.

The code above produces:

Code:

MAC-000DFEE029B2
MAC-0223333B2
MAC-abcde

Oh, and if you're worried that there might be other MVPWidth nodes in config and you want to make sure that you're getting the right MAC nodes, you can try an XPath like the following instead:

Code:

System.Xml.XmlNodeList nl= xml.SelectNodes("//node()[MVPWidth and MVPHeight and MVPOffsetX and MVPOffsetY]");

This XPath returns a nodeset of nodes that have a MVPWidth child AND a MVPHeight child AND a MVPOffsetX child AND a MVPOffsetY child.

Hopefully this makes things a little clearer as to some querying possibilities using XPath.

Thanks for the help. I was able to do what I wanted after you example.

A little clear still a lot to learn.
