似乎我在 XML 中的正则表达式不正确。请任何人都可以为我的问题提供正确的正则表达式吗？谢谢。
我一直在尝试使用 OpenNMS 设置 HTTP 收集器，以定期从网站收集数字，原始 HTML 代码类似于：
<!DOCTYPE HTML>
............
<i style="display:none" >opennms781opennms</i>
............
</body>
</html>
目标是收集opennms(number)opennms使用正则表达式之间的数字。
我已经按照OpenNMS HTTP Collector Wiki中的说明编辑了所需的 XML 文件，并且 OpenNMS 能够提取原始 HTML 数据并将它们记录在日志中，但是我仍然收到以下警告/错误：

我想知道是否有人知道可能导致此问题的原因？
