我会使用小书签。我有一个XPath相关，但我不知道它是否可以在IE中使用。我得走了，但是如果它在IE上可以工作，我会对其进行测试并给出。

Web开发人员从我的书签中获得的两个小书签站点：Subsimple的小书签和Squarefree的小书签。那里有很多有用的东西…

[编辑]好，我回来了。我拥有的小书签仅适用于FF，不是最佳选择。我终于重写了它，尽管使用了最初的想法。无法找到我找到它的地方。

扩展的JS：

function getNode(node)
{
  var nodeExpr = node.tagName;
  if (nodeExpr == null)  // Eg. node = #text
    return null;
  if (node.id != '')
  {
    nodeExpr += "[@id='" + node.id + "']";
    // We don't really need to go back up to //HTML, since IDs are supposed
    // to be unique, so they are a good starting point.
    return "/" + nodeExpr;
  }
// We don't really need this
//~   if (node.className != '')
//~   {
//~     nodeExpr += "[@class='" + node.className + "']";
//~   }
  // Find rank of node among its type in the parent
  var rank = 1;
  var ps = node.previousSibling;
  while (ps != null)
  {
    if (ps.tagName == node.tagName)
    {
      rank++;
    }
    ps = ps.previousSibling;
  }
  if (rank > 1)
  {
    nodeExpr += '[' + rank + ']';
  }
  else
  {
    // First node of its kind at this level. Are there any others?
    var ns = node.nextSibling;
    while (ns != null)
    {
      if (ns.tagName == node.tagName)
      {
        // Yes, mark it as being the first one
        nodeExpr += '[1]';
        break;
      }
      ns = ns.nextSibling;
    }
  }
  return nodeExpr;
}

var currentNode;
// Standard (?)
if (window.getSelection != undefined) 
  currentNode = window.getSelection().anchorNode;
// IE (if no selection, that's BODY)
else 
  currentNode = document.selection.createRange().parentElement();
if (currentNode == null)
{
  alert("No selection");
  return;
}
var path = [];
// Walk up the Dom
while (currentNode != undefined)
{
  var pe = getNode(currentNode);
  if (pe != null)
  {
    path.push(pe);
    if (pe.indexOf('@id') != -1)
      break;  // Found an ID, no need to go upper, absolute path is OK
  }
  currentNode = currentNode.parentNode;
}
var xpath = "/" + path.reverse().join('/');
alert(xpath);
// Copy to clipboard
// IE
if (window.clipboardData) clipboardData.setData("Text", xpath);
// FF's code to handle clipboard is much more complex 
// and might need to change prefs to allow changing the clipboard content.
// I omit it here as it isn't part of the original request.

您必须选择元素并激活小书签以获取其XPath。

现在，小书签版本（感谢Bookmarklet
Builder）：

IE
（我不得不将其分为两部分，因为IE不喜欢很长的书签（最大大小取决于IE版本！）。您必须先激活第一个（功能def），然后再激活第二个。经过IE6测试）

javascript:function getNode(node){var nodeExpr=node.tagName;if(!nodeExpr)return null;if(node.id!=''){nodeExpr+="[@id='"+node.id+"']";return "/"+nodeExpr;}var rank=1;var ps=node.previousSibling;while(ps){if(ps.tagName==node.tagName){rank++;}ps=ps.previousSibling;}if(rank>1){nodeExpr+='['+rank+']';}else{var ns=node.nextSibling;while(ns){if(ns.tagName==node.tagName){nodeExpr+='[1]';break;}ns=ns.nextSibling;}}return nodeExpr;}
javascript:function o__o(){var currentNode=document.selection.createRange().parentElement();var path=[];while(currentNode){var pe=getNode(currentNode);if(pe){path.push(pe);if(pe.indexOf('@id')!=-1)break;}currentNode=currentNode.parentNode;}var xpath="/"+path.reverse().join('/');clipboardData.setData("Text", xpath);}o__o();

FF

javascript:function o__o(){function getNode(node){var nodeExpr=node.tagName;if(nodeExpr==null)return null;if(node.id!=''){nodeExpr+="[@id='"+node.id+"']";return "/"+nodeExpr;}var rank=1;var ps=node.previousSibling;while(ps!=null){if(ps.tagName==node.tagName){rank++;}ps=ps.previousSibling;}if(rank>1){nodeExpr+='['+rank+']';}else{var ns=node.nextSibling;while(ns!=null){if(ns.tagName==node.tagName){nodeExpr+='[1]';break;}ns=ns.nextSibling;}}return nodeExpr;}var currentNode=window.getSelection().anchorNode;if(currentNode==null){alert("No selection");return;}var path=[];while(currentNode!=undefined){var pe=getNode(currentNode);if(pe!=null){path.push(pe);if(pe.indexOf('@id')!=-1)break;}currentNode=currentNode.parentNode;}var xpath="/"+path.reverse().join('/');alert(xpath);}o__o();
