今天安装Windows Live Writer并用WLW发布文章时，发现有“乱码”，具体现象是html标记中的 < 、 > 、 & 这三个符号被自动去掉了，导致在WordPress中文章排版有问题。
g了下，原来是处理xml的函数libxml2（version 2.7.0 – 2.7.3 ）的bug。
解决办法有两种(详见：http://thinkland.twbbs.org/189.html )
1. 升级libxml2
2. 修改WordPress三个代码文件
//———————————————–

function parse($xml) {
global $app_logging;
array_unshift($this->ns_contexts, array());
$parser = xml_parser_create_ns();
xml_set_object($parser, $this);
xml_set_element_handler($parser, “start_element”, “end_element”);
xml_parser_set_option($parser,XML_OPTION_CASE_FOLDING,0);
xml_parser_set_option($parser,XML_OPTION_SKIP_WHITE,0);
xml_set_character_data_handler($parser, “cdata”);
xml_set_default_handler($parser, “_default”);
xml_set_start_namespace_decl_handler($parser, “start_ns”);
xml_set_end_namespace_decl_handler($parser, “end_ns”);
$contents = “”;
//xmllib 2.7.0 -2.7.3 stripping leading angle brackets bug patch
$xml =str_replace(“<”,”<”,$xml );
$xml =str_replace(“>”,”>”,$xml );
$xml =str_replace(“&”,”&”,$xml );
//end Fix
xml_parse($parser, $xml);
xml_parser_free($parser);
return true;
}

$this->error( $errormsg );
}
}
xml_parser_free( $this->parser );
$this->normalize();
}

}
$this->_parser = xml_parser_create();
// Set XML parser to take the case of tags in to account

if (!xml_parse($this->_parser, $this->message)) {

return false;
}
xml_parser_free($this->_parser);
// Grab the error messages, if any
if ($this->messageType == ‘fault’) {
$this->faultCode = $this->params[0]['faultCode'];
$this->faultString = $this->params[0]['faultString'];
}
return true;
}
我折腾了半天，选用第二种；
结果验证简单，有效果，现在这篇文章就是用WLW发布的。
