javascript - 在React-Native中使用正则表达式时出错-无效的正则表达式：无效的组说明符名称

我需要从<!DOCTYPE html> <html lang="en" dir="ltr"> <head> <meta charset="utf-8"> <title>Calendar</title> <link rel="stylesheet" href="calendar.css"> <script type="text/javascript" src="calendar.js" async></script> </head> <body> <div class="c_container"> <div class="c_November" > <h2 id="c_title">November 2020</h2> </div> <table id="c_calendar" > <tr> <th class="c_weekdays c_th">Week</th> <th class="c_weekdays c_th">Mon</th> <th class="c_weekdays c_th">Tue</th> <th class="c_weekdays c_th">Wed</th> <th class="c_weekdays c_th">Thu</th> <th class="c_weekdays c_th">Fri</th> <th class="c_weekdays c_th">Sat</th> <th class="c_weekdays c_th">Sun</th> </tr> <tr> <td class="c_week " >44</td> <td class="c_graydays c_td" >26</td> <td class="c_graydays c_td" >27</td> <td class="c_graydays c_td" >28</td> <td class="c_graydays c_td" >29</td> <td class="c_graydays c_td" >30</td> <td class="c_graydays c_weekend c_td" >31</td> <td class="c_weekend c_td">1</td> </tr> <tr> <td class="c_week " >45</td> <td class="c_td">2</td> <td class="c_td">3</td> <td class="c_td">4</td> <td class="c_td">5</td> <td class="c_td">6</td> <td class="c_weekend c_td">7</td> <td class="c_weekend c_td">8</td> </tr> <tr> <td class="c_week ">46</td> <td class="c_td">9</td> <td class="c_td">10</td> <td class="c_td">11</td> <td class="c_td">12</td> <td class="c_td">13</td> <td class="c_weekend c_td">14</td> <td class="c_weekend c_td">15</td> </tr> <tr> <td class="c_week" >47</td> <td class="c_td">16</td> <td class="c_td">17</td> <td class="c_td">18</td> <td class="c_expedition c_td">19 <span class="c_expeditiontext"> Thursday the 19th of November all pupils will have an expedition to damlia, our local dam.

"

我需要获取：<img src="file:///data/user/0/com.app/cache/ImagePicker/2b807bcc-f622-4019-abf1-6875c1130a09.jpg"></div><br><div>

为此我使用以下正则表达式："file:///data/user/0/com.app/cache/ImagePicker/2b807bcc-f622-4019-abf1-6875c1130a09.jpg"

但这给了我这个错误：

但可以在在线编辑器中对其进行测试：

我该如何解决？，谢谢：）
