Question

我知道它可能是重复但我无法从此HTML源中提取值。任何帮助将不胜感激。

所以我要做的是从页面获取项目的pid。正在从csv文件中读取项目的名称，我需要获取pid。

例如，如果这里的项目是“AA项目”，也可以使用项目密钥“AA”，需要提取的pid是 10441 。

由于这些值不是标签，我无法弄清楚如何提取它们。

更新：只需使用pid =（\ d ....）即可获得所有pid，而不会引用任何项目名称或密钥。

我不建议使用正则表达式来解析HTML数据，因为开发和维护会很困难，而且对标记更改非常敏感，因此非常脆弱，有关详细信息，请参阅https://stackoverflow.com/a/1732454/2897748。

转而使用XPath Extractor，相关配置为：

参考名称：任何有意义的内容，即//JasperPrint is already filled HttpServletResponse httpServletResponse = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse(); httpServletResponse.setContentType("application/csv; charset=cp1252"); httpServletResponse.setCharacterEncoding("cp1252"); httpServletResponse.addHeader("Content-disposition", "attachment; filename=nameoffile.csv"); httpServletResponse.addHeader("Content-type", "application/csv; charset="+Charset.forName("utf-8").displayName()); ServletOutputStream servletOutputStream = httpServletResponse.getOutputStream(); JRCsvExporter exporter = new JRCsvExporter(); exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint); exporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "cp1252"); exporter.setParameter(JRExporterParameter.OUTPUT_STREAM, servletOutputStream); exporter.setParameter(JRCsvExporterParameter.CHARACTER_ENCODING, "cp1252"); exporter.setParameter(JRCsvExporterParameter.FIELD_DELIMITER, ";");
XPath查询：def super_sum(*args): total = 0 args = list(args) if len(args) == 1: args = args[0] for d in args: if isinstance(d, list): total += super_sum(d) else: total += d return total print super_sum([1, 2, [3, 4], 5], 3, [2, 3])
