Html xpath返回不带'；根本不包含某个节点

我正在使用xpath定位html标记。我有一个有5行的表，我想根据表行中一些表数据标记中的类来选择行

<table class="layoutDataDefinitionTable grid-row-table">
    <thead/>
    <tbody>
        <tr id="row_0"/>
            <td data-dojo-attach-point="_iconNode"/>
            <td class="dgrid-cell-padding dgrid-no-left"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
        <tr id="row_1">
            <td data-dojo-attach-point="_iconNode" class="arrowDown"/>
            <td class="dgrid-cell-padding dgrid-no-left"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
        <tr id="row_2">
            <td data-dojo-attach-point="_iconNode"/>
            <td class="dgrid-cell-padding dgrid-no-left dgrid-cell-indent"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
        <tr id="row_3">
            <td data-dojo-attach-point="_iconNode" class="arrowDown"/>
            <td class="dgrid-cell-padding dgrid-no-left"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
        <tr id="row_4">
            <td data-dojo-attach-point="_iconNode" class="arrowDown"/>
            <td class="dgrid-cell-padding dgrid-no-left"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
            <td class="dgrid-cell-padding"/>
    </tbody>
</table>

但这只是返回所有的行，因为每一行都有一个td，它不包含这两个类。我只希望它返回第0行。

您可以将谓词移动到

tr

，并检查所有

td

子级，查看它们是否都满足不包含所需类的条件：

//表[contains（@class，'layoutDataDefinitionTable grid row table'）]/tbody/tr[not（contains（td/@class，'dgrid cell padding dgrid no left dgrid cell indent'））和not（contains（td/@class，'arrowDown'））]

---

这将只返回id为0行的

tr

，您可以将谓词移动到

tr

，并检查所有

td

子级，查看它们是否都满足不包含所需类的条件：

//表[contains（@class，'layoutDataDefinitionTable grid row table'）]/tbody/tr[not（contains（td/@class，'dgrid cell padding dgrid no left dgrid cell indent'））和not（contains（td/@class，'arrowDown'））]

这将仅返回id为第0行的

tr

$x("//table[contains(@class, 'layoutDataDefinitionTable grid-row-table')]//tbody//tr//td[not(contains(@class, 'dgrid-cell dgrid-cell-padding dgrid-no-left dgrid-cell-indent')) and not(contains(@class, 'arrowDown'))]/..");
