我正在废弃网站以收集有关属性的一些数据。我正在尝试获取所有者名称，并最终获得<span class="label">之后的所有其他文本属性。以下是我在查询表达式normalize-space(//span[(@class='label') and contains(., 'Owner:')]/following-sibling::text())方面的内容，我使用FirePath评估了表达式，并返回了正确的字符串，但是，在Google表格中，返回的值为空。有什么建议吗？

答案 0 :(得分：1)
您可以通过修改稍微查询的URL来执行此操作 - 例如，我发现包含所需原始数据的端点如下所示：http://www.oasisnyc.net/service.svc/lot/3033030022?layerstoselect=
然后使用此公式，您可以将原始URL转换为正确的端点：
="http://www.oasisnyc.net/service.svc/lot/"®EXEXTRACT(A1,"lot:(\d+)")&"?layerstoselect="
如果您使用=transpose(IMPORTDATA(B1))提取数据，您会看到包含所有字段的列，具体取决于您希望如何排列数据，然后您可以使用arrayformula和whatnot来清理/转换单独的数据它们根据需要...例如，如果您想要列中的标题和数据，您可以输入：
=arrayformula(regexreplace({iferror(ARRAYFORMULA(REGEXEXTRACT(transpose(IMPORTDATA(B1)),"(\w+):"))),iferror(ARRAYFORMULA(REGEXEXTRACT(transpose(IMPORTDATA(B1)),":""?(.*)""?")))},"""",""))
如果你想转置成一行，请将整个内容换成转置：
=transpose(arrayformula(regexreplace({iferror(ARRAYFORMULA(REGEXEXTRACT(transpose(IMPORTDATA(B1)),"(\w+):"))),iferror(ARRAYFORMULA(REGEXEXTRACT(transpose(IMPORTDATA(B1)),":""?(.*)""?")))},"""","")))
