java - 在java中提取除包含HTML表的字符串之外的所有字符串数据

Question

我有一个像这样的长字符串。

<p>Some Text above the tabular data. I hope this text will be seen.</p>

<table border="1" cellpadding="0" cellspacing="0">
    <tbody>
        <tr>
            <td style="width:150px">
            <p>S.No.</p>
            </td>



            </td>
        </tr>
        <tr>
            <td style="width:150px">
            <p>2</p>
            </td>


    </tbody>
</table>

<p>&nbsp;</p>

<p>Please go through this tabular data.</p>

<table border="1" cellpadding="0" cellspacing="0">
    <tbody>
        <tr>
            <td style="width:150px">
            <p>S.No.</p>
            </td>


        </tr>
        <tr>
            <td style="width:150px">
            <p>1</p>
            </td>


        <tr>
            <td style="width:150px">
            >
            </td>

            </td>
        </tr>
    </tbody>
</table>


<p>End Of String</p>

现在我想在 html 表之前和之后提取整个字符串，如下所示。并添加“HTML Table...”来代替 HTML Table。我尝试了一些事情但未能实现。尝试拆分成数组，但没有成功

示例输出

<p>Some Text above the tabular data. I hope this text will be seen.</p>

<p>&nbsp;</p>
HTML Table.... 
<p>Please go through this tabular data.</p>


<p>End Of String</p>

Answer 1

您可以使用正则表达式处理多行和不区分大小写的标志(?is)，通过String.replaceAll简单地完成此操作:

String noTables = longTableString.replaceAll("(?is)(\\<table .*?\\</table\\>)", "HTML Table...");
// result
<p>Some Text above the tabular data. I hope this text will be seen.</p>

HTML Table...

<p>&nbsp;</p>

<p>Please go through this tabular data.</p>

HTML Table...


<p>End Of String</p>
