Hello.

Something strage happens when I try to compare a string value (value of
XML attribute) with ">", "<" or ">=", "<=" operators. Looks like only
"=" works for strings comparison in MSXML. :-(

The following XPath queries always returns 0 nodes:

  //Order [ @Location <= 'M' ]
  //Order [ @Location >= 'M' ]

but the query:

  //Order [ @Location = 'M100' ]

returns 1 node in list. So, I assume that there are problems with "<"
and ">" comparison operators in MSXML.

But I need less- and greather- comparisons for strings! Could you
please help me to solve this issue? Maybe there are some
workarounds?...

Below you can see test script (JScript), xml sample and output sample:

===test-script:begin===
var XmlName = "order.xml";
var xmlDoc = new ActiveXObject("Msxml2.DOMDocument.4.0");
xmlDoc.async = false;
xmlDoc.resolveExternals = false;
xmlDoc.load(XmlName);
xmlDoc.setProperty("SelectionLanguage", "XPath");
if (xmlDoc.parseError.errorCode == 0)
{
  WScript.Echo("XML successfully loaded.");
  var query = "//Order [ @Location = 'M100' ]";
  var nodesList = xmlDoc.selectNodes(query);
  WScript.Echo(nodesList.length + " nodes selected by { " + query + "
}");

  query = "//Order [ @Location >= 'M' ]";
  nodesList = xmlDoc.selectNodes(query);
  WScript.Echo(nodesList.length + " nodes selected by { " + query + "
}");

  query = "//Order [ @Location <= 'M' ]";
  nodesList = xmlDoc.selectNodes(query);
  WScript.Echo(nodesList.length + " nodes selected by { " + query + "
}");
}
===test-script:end===

===order.xml:begin===
<Order Location="M100"/>
===order.xml:end===

===script console output sample:begin===
XML successfully loaded.
1 nodes selected by { //Order [ @Location = 'M100' ] }
0 nodes selected by { //Order [ @Location >= 'M' ] }
0 nodes selected by { //Order [ @Location <= 'M' ] }
===script console output sample:end===


WBR,
Dmitry.

ps. Tested with MSXML 4.0sp2 and 6.0.
