Splinter如何获得作为<span>输出的文本，

Question

我有一个<tr>，它的id是由Javascript代码动态生成的，所以我不能使用find_by_id来选择它。如果我不知道包含<tr>标记的id是什么，我如何使用Splinter访问span中的文本？

<tr id="treeview-1020-record-b3250a58-46d6-4df8-9e04-69d82afcc966" data-boundview="treeview-1020" data-recordid="b3250a58-46d6-4df8-9e04-69d82afcc966" data-recordindex="22" class="x-grid-row x-grid-tree-node-expanded x-grid-data-row" tabindex="-1">
<td class="x-grid-cell x-grid-td x-grid-cell-treecolumn-1019 x-grid-cell-treecolumn x-grid-cell-first x-grid-cell-last x-unselectable x-grid-cell-treecolumn">
<div unselectable="on" class="x-grid-cell-inner" style="text-align:left;">
<span class="x-tree-node-text">WZ1MZ35_G2 ADV.</span>
</div>
</td>
</tr>

选择所有tr标签。查找以正确字符串开头的字符串。从该节点搜索所有跨度标记。并提取文本

allTR = document.getElementsByTagName('tr');
for (let trIdx = 0; trIdx < allTR.length; trIdx++) {
const trElem = allTR[trIdx];
if (trElem.getAttribute('id').startsWith('treeview-1020-')) {
allSpan = trElem.getElementsByTagName('span');
if (allSpan.length === 0) continue;
spanText = allSpan[0].textContent
// do something usefull with the text
}
}
