在搜索互联网一段时间后,我发现有很多在线工具允许从符号转换为HTML编号,但反之亦然。
我正在寻找工具/在线工具/ php脚本将html编号转换回符号
例如:
& -> &
然后回到
& -> &
有人知道吗?

你可以在java中使用:
import org.apache.commons.lang.StringEscapeUtils
并使用StringEscapeUtils.unescapeHtml(String str) method
例如输出:
System.out.println(StringEscapeUtils.unescapeHtml("@"));
@
System.out.println(StringEscapeUtils.unescapeHtml("€"));
-
System.out.println(StringEscapeUtils.unescapeHtml("–"));
€

对于PHP:Google搜索找到了htmlentities和html_entity_decode:
<?php
$orig = "I'll \"walk\" the <b>dog</b> now";
$a = htmlentities($orig);
$b = html_entity_decode($a);
echo $a; // I'll "walk" the <b>dog</b> now
echo $b; // I'll "walk" the <b>dog</b> now
// For users prior to PHP 4.3.0 you may do this:
function unhtmlentities($string)
{
// replace numeric entities
$string = preg_replace('~&#x([0-9a-f]+);~ei', 'chr(hexdec("\\1"))', $string);
$string = preg_replace('~&#([0-9]+);~e', 'chr("\\1")', $string);
// replace literal entities
$trans_tbl = get_html_translation_table(HTML_ENTITIES);
$trans_tbl = array_flip($trans_tbl);
return strtr($string, $trans_tbl);
}
$c = unhtmlentities($a);
echo $c; // I'll "walk" the <b>dog</b> now
?>
对于.NET您可以编写一些使用HTMLEncode或HTMLDecode的简单内容。例如:
<强> HTMLDecode 强>
[Visual Basic]
Dim EncodedString As String = "This is a <Test String>."
Dim writer As New StringWriter
Server.HtmlDecode(EncodedString, writer)
Dim DecodedString As String = writer.ToString()
[C#]
String EncodedString = "This is a <Test String>.";
StringWriter writer = new StringWriter();
Server.HtmlDecode(EncodedString, writer);
String DecodedString = writer.ToString();

我相信这些数字中的大多数只是ASCII或unicode值,因此您需要做的就是查找与该值相关联的符号。对于非unicode符号,这可以像(python脚本)一样简单:
#!/usr/bin/python
import sys
# Iterate through all command line arguments
for entity in sys.argv:
# Extract just the digits from the string (discard the '&#' and the ';')
value = "".join([i for i in entity if i in "0123456789"])
# Get the character with that value
result = chr(value)
# Print the result
print result
然后用:
调用它python myscript.py "&"
这可能很容易被翻译成php或其他东西,基于:
<?php
$str = "The string ends in ampersand: ";
$str .= chr(38); /* add an ampersand character at the end of $str */
/* Often this is more useful */
$str = sprintf("The string ends in ampersand: %c", 38);
?>
(取自here因为我不知道php!)。当然,这需要修改以转换“&amp;”进入38,但我会把它留给那些知道php的人练习。
