Result Type Defined ConstantValueDescription
ANY_TYPE0A result set containing whatever type naturally results from evaluation of the expression. Note that if the result is a node-set then UNORDERED_NODE_ITERATOR_TYPE is always the resulting type.
NUMBER_TYPE1A result containing a single number. This is useful for example, in an XPath expression using the count() function.
STRING_TYPE2A result containing a single string.
BOOLEAN_TYPE3A result containing a single boolean value. This is useful for example, in an XPath expression using the not() function.
UNORDERED_NODE_ITERATOR_TYPE4A result node-set containing all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document.
ORDERED_NODE_ITERATOR_TYPE5A result node-set containing all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document.
UNORDERED_NODE_SNAPSHOT_TYPE6A result node-set containing snapshots of all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document.
ORDERED_NODE_SNAPSHOT_TYPE7A result node-set containing snapshots of all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document.
ANY_UNORDERED_NODE_TYPE8A result node-set containing any single node that matches the expression. The node is not necessarily the first node in the document that matches the expression.
FIRST_ORDERED_NODE_TYPE9A result node-set containing the first node in the document that matches the expression.

snapshotItem() は {{domxref("XPathResult")}} インターフェイスのメソッドで、アイテムのスナップショットのコレクション、または添字がノードの範囲を外れている場合は null を返します。イテレーターの返値とは異なり、スナップショットは無効になることはありませんが、変更したときに現在の文書に対応しない場合があります。

+ +

構文

+ +
var node = result.snapshotItem(i);
+
+ +

返値

+ +

XPathResult のノードセット内の指定された添字の {{domxref("Node")}} です。

+ +

例外

+ +

TYPE_ERR

+ +

{{domxref("XPathResult.resultType")}} が UNORDERED_NODE_SNAPSHOT_TYPE または ORDERED_NODE_SNAPSHOT_TYPE でない場合、 {{domxref("XPathException")}} による例外が TYPE_ERR 型で発生します。

+ +

例

+ +

以下の例は snapshotItem() メソッドの使用例を表しています。

+ +

HTML

+ +
<div>XPath example</div>
+<div>Tag names of the matched nodes: <output></output></div>
+
+ +

JavaScript

+ +
var xpath = "//div";
+var result = document.evaluate(xpath, document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);
+var node = null;
+var tagNames = [];
+for(var i = 0; i < result.snapshotLength; i++) {
+  var node = result.snapshotItem(i);
+  tagNames.push(node.localName);
+}
+document.querySelector("output").textContent = tagNames.join(", ");
