Query XML Using JQuery or Javascript

Just a comment:

Storing passwords is a sever security issue. Stored salted hashes instead. See Plain Text Offenders.

When there is a use-case to store it, then store it encrypted.

Like this

https://jsfiddle.net/mplungjan/4fwxhszv/

const findRoot = password => $(xml).find("Password")
  .filter(
    function() { return this.textContent.trim() === password }
    ).next().text();
console.log(findRoot("456"))
console.log(findRoot("482"))

Select allOpen in new window

Hi,

have a look here:
https://codepen.io/jeschor/pen/jOGgNvB

let xmlString = "<Folders><Folder><Password>123</Password><Root>abc</Root></Folder><Folder><Password>456</Password><Root>def</Root></Folder><Folder><Password>789</Password><Root>ghi</Root></Folder></Folders>";

function findInXml()
{
  var xmlDoc = $.parseXML( xmlString );
  $xml = $( xmlDoc );
  var found = false;
  $xml.find("Folder").each(function() {
    var currentFolder = $(this);
    $rt = currentFolder.find("Password").text() == $('#queryValue').val() ? $(this).find( "Password" ) : false;
  if ($rt)
    {
      found = true;
      $("#result").val($rt.parent().children("Root").text());
    }
  });
  if (found == false)
    {
      $("#result").val("Not Found");
    }
}

Select allOpen in new window

This one works.  One thing.  How do I load a string (xml) from the XML file?

const xml = `<Folders>
    <Folder>
        <Password>123</Password>
        <Root>abc</Root>
    </Folder>

    <Folder>
        <Password>456</Password>
        <Root>def</Root>
    </Folder>

    <Folder>
        <Password>789</Password>
        <Root>ghi</Root>
    </Folder>
</Folders>`
const findRoot = password => $(xml).find("Password")
  .filter(
    function() { return this.textContent.trim() === password }
    ).next().text();
console.log(findRoot("456"))
console.log(findRoot("482"))

Thanks!
