需要 select 特定元素在使用 Java 的 Selenium Webdriver 中使用 XPath

Question

我遇到了一个找不到答案的问题。我通常擅长 selecting 这个意大利面条数字代码中的特定元素。这次我难住了。这是代码...

<div id="widget_dijit_form_DateTextBox_0_dropdown" class="dijitPopup dijitCalendarPopup" style="visibility: visible; top: 179.55px; z-index: 1000; left: 217.9px; right: auto; display: none;" role="presentation" dijitpopupparent="dijit_form_DateTextBox_0">
    <table id="dijit_form_DateTextBox_0_popup" class="dijitCalendarContainer dijitCalendar" lang="" cellspacing="0" cellpadding="0" aria-labelledby="dijit_form_DateTextBox_0_popup_year" dojoattachevent="onkeypress: _onKeyPress" role="grid" style="-moz-user-select: none; top: 0px; overflow: hidden; width: 259px; visibility: visible;" dir="" widgetid="dijit_form_DateTextBox_0_popup">
        <thead>
            <tbody class="dijitReset dijitCalendarBodyContainer" dojoattachevent="onclick: _onDayClick, onmouseover: _onDayMouseOver, onmouseout: _onDayMouseOut, onmousedown: _onDayMouseDown, onmouseup: _onDayMouseUp">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1463904000000">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1463990400000">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1464076800000">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1464163200000">
                    <td class="dijitCalendarSelectedDate dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1464249600000" tabindex="0">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1464336000000">
                        <span class="dijitCalendarDateLabel">27</span>
                    </td>
...
...                 
<div id="widget_dijit_form_DateTextBox_1_dropdown" class="dijitPopup dijitCalendarPopup" style="visibility: visible; top: 225px; z-index: 1000; left: 217.9px; right: auto;" role="presentation" dijitpopupparent="dijit_form_DateTextBox_1">
    <table id="dijit_form_DateTextBox_1_popup" class="dijitCalendarContainer dijitCalendar dijitCalendarHover dijitHover dijitCalendarFocused dijitCalendarHoverFocused dijitHoverFocused dijitFocused" lang="" cellspacing="0" cellpadding="0" aria-labelledby="dijit_form_DateTextBox_1_popup_year" dojoattachevent="onkeypress: _onKeyPress" role="grid" style="-moz-user-select: none; top: 0px; overflow: hidden; width: 255px; visibility: visible;" dir="" widgetid="dijit_form_DateTextBox_1_popup">
        <thead>
            <tbody class="dijitReset dijitCalendarBodyContainer" dojoattachevent="onclick: _onDayClick, onmouseover: _onDayMouseOver, onmouseout: _onDayMouseOut, onmousedown: _onDayMouseDown, onmouseup: _onDayMouseUp">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                <tr class="dijitReset dijitCalendarWeekTemplate" role="row">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1432454400000">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1432540800000">
                    <td class="dijitCalendarCurrentDate dijitCalendarCurrentMonth dijitCalendarDateTemplate" role="gridcell" dijitdatevalue="1432627200000" tabindex="0">
                    <td class="dijitCalendarCurrentMonth dijitCalendarDateTemplate dijitCalendarHoveredDate" role="gridcell" dijitdatevalue="1432713600000">
                        <span class="dijitCalendarDateLabel">27</span>
                    </td>

我正在尝试 select 第二个“27”。如果我使用这个 xpath 语句

//*[contains(@class, 'dijitCalendarCurrentMonth')][contains(., '27')]

它return是两个元素。所以，我只需要 select

下面的那个

id="dijit_form_DateTextBox_1_popup"

我试过以下...全部return没有匹配的节点...

//*[@id='dijit_form_DateTextBox_1_popup' and contains(@class, 'dijitCalendarCurrentMonth') and contains(., '27')]
//*[@id='dijit_form_DateTextBox_1_popup'][contains(@class, 'dijitCalendarCurrentMonth')][contains(., '27')]
//*[@id='dijit_form_DateTextBox_1_popup'][contains(@class, 'dijitCalendarCurrentMonth') and contains(., '27')]

我做错了什么？

Answer 1

对于 [@id='dijit_form_DateTextBox_1_popup']，您正在寻找 table 标签本身中的文本 27，它不包含文本 27。如果您删除它，它应该找到包含 span 的 td，其中包含文本 27。而且，由于 td 没有任何具有 [@id='dijit_form_DateTextBox_1_popup'] 的 id 属性，它也找不到任何匹配项。尝试

//table[@id='dijit_form_DateTextBox_1_popup']//span[contains(.,'27')]

我还看到 span 包含文本 27 是 table 中唯一的 span。为了获得更好的性能，我认为您应该尝试以下 css。

#dijit_form_DateTextBox_1_popup span
