使用Tidy重新格式化后，修复XML文件中的CDATA块

Posted 2021-02-23

For some reason tidy inserts new lines before/after

# command line/exec(),etc. or use the php functions to tidy up your document
tidy -indent -utf8 -xml -wrap 1000 input.xml > output.xml
 
<?php
/**
  * Replaces invalid:
  * <element>
  *     <![CDATA[whatever content]]>
  * </element>
  *
  * With well-formed:
  * <element><![CDATA[whatever content]]></element>
  */
$out = preg_replace('~>[s	w

]+<![CDATA[~', '><![CDATA[', file_get_contents("output.xml"));
$out = preg_replace('~]]>s+<~', ']]><', $out);
file_put_contents("final.xml", $out);
?>
