How do I get the attribute values of a node that contains a certain string?
For example..
Say, I have an array of strings or IEnumerable of strings containing strings like

and the file contains nodes like
<x-aln freq="fq1">abldfls lfds fd \hbox{x1}</x-aln>
<x-aln freq="fq2">abldfls lfds fd \hbox{x2}</x-aln>
<x-aln freq="fq3-5">abldfls lfds fd \hbox{z5} dafdsf \hbox{z6} dsfdsf \hbox{z7}</x-aln>
How do I search for all the string in the array to check whether they are inside any of the
, if yes, then get the attribute value freq of its parent node <x-aln> and store them in a variable?

What I have tried:

I can't figure out how can I do this...
Can anyone help??

so plz convey me the total xml file

1 solution

sir first create a xml file named as test1.xml and stored in the debug folder in win application given bellow that manupulating your first xml code

        <x-aln freq="fq1">abldfls lfds fd \hbox{x1}</x-aln>
<x-aln freq="fq2">abldfls lfds fd \hbox{x2}</x-aln>
<x-aln freq="fq3-5">abldfls lfds fd \hbox{z5} dafdsf \hbox{z6} dsfdsf \hbox{z7}</x-aln>
    <foo id="123">Text 1<moo />Text 2

then the code behind I define bellow

private void button5_Click(object sender, EventArgs e)

          string fpath = Application.StartupPath + "\\" + "test1.xml";
          XDocument xele = XDocument.Load(fpath);

          var node = xele.XPathSelectElement("/xml/foo/x-aln[@freq='fq1']");
          var strvalue = node.Value;
          int ind = strvalue.IndexOf('\\');
          string str = "";
          if (strvalue.Substring(ind + 1, 5) == "hbox{")
              int lind = strvalue.LastIndexOf('}');
              str = strvalue.Substring(ind + 6, (lind-(ind + 6)));

This give a message box but you can take with a variable

Hi, I want to get the attribute value of the node i.e. since x1 is inside the node <x-aln freq="fq1">abldfls lfds fd \hbox{x1}</x-aln>, so the output should get me the attrib value freq i.e. fq1, but your code outputs x1?

BTW, My XPath is a bit rusty, can you show it using LINQ2XML?
