regex - how to change `&lt;` to `<` in a string only inside `code` tag using regexp with javascript? -


i want replace &lt; < in string only inside code tag (here point)

for example, here string:

<pre><code class="lang-html">&lt;style&gt;   .mydiv {     width: 150px;     height: 200px;     background: red;     border-top-left-radius: 100%;   } &lt;/style&gt; &lt;div class=&quot;mydiv&quot;&gt;&lt;/div&gt; </code></pre>

but don't know how write exact regular expression.

i write down below:

var str = `<pre><code class="lang-html">&lt;style&gt;   .mydiv {     width: 150px;     height: 200px;     background: red;     border-top-left-radius: 100%;   } &lt;/style&gt; &lt;div class=&quot;mydiv&quot;&gt;&lt;/div&gt; </code></pre> `  str = str   .replace(/<code(.|\n|\t|\f|\r|\v)+?(&lt;)(.|\n|\t|\f|\r|\v)+<\/code>/g, (a) => {     return ''   })  console.log(str)

the regular expression can match string, don't how next.

one more question, (.|\n|\t|\f|\r|\v)+? work, [.\n\t\f\r\v] not work, why?

thanks in advance!

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
