从输出中剥离空白行

我有为Google购物创建XML文档的代码。谷歌正在挂起一条空白线路。我不知道如何去掉线条。该代码正在从Magento Commerce数据库中提取。从输出中剥离空白行

的第一项通过的描述标签有没有空行，但第二项没有问题，给我一个XML格式错误，唯一我能想到的是在描述标签的空行

你可以尝试剥离出这样

<description><?php echo str_replace(array("\r\n", "\n"), ' ', $row['short_description']); ?></description>

换行符

请参阅PHP手册中的str_replace()函数。

你可以试试这个功能

function removeSpaces($buffer){ 
    $buffer = str_replace(array('\n', '\r'), array('', ''), $data); 
    return $buffer; 
} 

@ob_start("ob_gzhandler"); 
@ob_start("removeSpaces");

将这个任意PHP页面的顶部，它会采取你的问题的关心

的trim()功能将的开头和结尾删除空格串。如果你想从字符串中的任何地方发生的删除换行符，你可以做这样的事情：

str_replace(array("\n","\r\n"), "", $row['short_description'];);

如果你有过如何将数据存储在数据库中的任何控制，我会考虑“清理“输入具有类似的功能，因此您不必混淆此页面。

你可以把它改成这样的：

[...snip...] 
      echo $row2['value']; 
} ?></g:brand> <---closing tag up against closing PHP tag 
<g:mpn><?php echo $row['sku']; ?></g:mpn> 
</item> 
<?php <---eliminated blank lines before php tag 
} 
mysql_close($con); 
?> 
[...snip...]
