Question

硒，Chrome WebDriver，Java。

尝试使用以下代码循环引发行并得到意外行为。

 List<WebElement> divs = driver.findElementsByXPath("//div[@class = \"w-dyn-items\"][contains(.//*,'2019')]/div[@class = \"w-dyn-item\"][position() < 30]")
    for (WebElement div : divs) {
        DocumentWrapper doc = new DocumentWrapper()
        try {
            //grab document stuff
            doc.title = div.findElementByXPath("//h1").getText()
            log.info("\tTitle: ${doc.title}")
            doc.dateStr = div.findElementByXPath("//div[@class=\"meta-tag\"]").getText()
            log.info("\tDate: ${doc.dateStr}")
            String google_drive_link = div.findElementByXPath("//a[@class=\"drop-link\" and contains(. ,\"PDF Agenda\")]").getAttribute('href')
            log.info("\traw Url: ${google_drive_link}")

我得到的结果只是相同标题，日期和一遍又一遍的链接的重复

现在，从技术上讲，这些不是表格行，而是一系列div。但是它们不应该一样工作吗？如果没有，谁可以向我解释为什么这不应该工作？

我要从https://www.cityofalhambra.org/city-meetings提取数据

Answer 1

好吧，我在github.io上阅读了Selenium文档，并找到了它。

它表示我们应该在XPath之前使用一个点作为相对路径。这是我最初的本能，但在以前的作品中，使用该点时出现了错误。将重试并更新我的答案。

更新*修复了！
