XML分析錯誤...找不到元素

Question

我有一個腳本生成突然停止工作的XML文檔。當我運行它，我得到這個錯誤：

XML解析錯誤：沒有的元素中找到 地點：http://www.mydomain.com/indeed-general-xml/ 1號線，1列：

下面是生成節點結構的代碼和循環：

header('Content-Type: text/xml'); 
    //create DOMDocument object and set char encoding 
    $doc = new DOMDocument('1.0','utf-8'); 
    $doc->formatOutput = true; 

    //root element 
    $r = $doc->createElement("source"); 
    //append root element to our document 
    $doc->appendChild($r); 

    $publisher = $doc->createElement("publisher"); 
    $publisher->appendChild($doc->createTextNode("mydomain.com")); 
    $r->appendChild($publisher); 

    $publisherurl = $doc->createElement("publisherurl"); 
    $publisherurl->appendChild($doc->createTextNode("http://mydomain.com")); 
    $r->appendChild($publisherurl); 

    $job = array(); 
    //set args for query 
    $args = array(
     'post_author' => -1, 
     'post_type' => 'job_listing', 
     'posts_per_page' => -1, 
     'post_status' => 'publish', 
     'orderby' => 'date', 
     'order' => 'DESC' 
     ); 
    //run query 
    $feed_jobs = new WP_Query($args);while($feed_jobs->have_posts()) : $feed_jobs->the_post(); 
    $b = $doc->createElement("job"); 

    //begin loop 
    (while $feed_jobs->have_posts()) : $feed_jobs->the_post(); 

    $title = $doc->createElement("title");  
    $title->appendChild($doc->createCDATASection($post->post_title)); 
    $b->appendChild($title); 

    $company_name = "Sample Company Name"; 
    $company = $doc->createElement("company"); 
    $company->appendChild($doc->createCDATASection($company_name)); 
    $b->appendChild($company); 

    $date = $doc->createElement("date"); 
    $date->appendChild($doc->createCDATASection($post->post_date)); 
    $b->appendChild($date); 

    $referencenumber = $doc->createElement("referencenumber"); 
    $referencenumber->appendChild($doc->createCDATASection($post->ID)); 
    $b->appendChild($referencenumber); 

    $url = $doc->createElement("url"); 
    $url->appendChild($doc->createCDATASection($post->guid)); 
    $b->appendChild($url); 

    $description = $doc->createElement("description"); 
    $description = createCDATASection($post->post_content); 
    $description->appendChild($description); 
    $b->appendChild($description); 

    //query postmeta table for city and state// then parse it into an array 
    $location = get_post_meta($post->ID,'geo_address',true); 
    $location = explode(',',$location); 

    $city = $doc->createElement("city"); 
    $city->appendChild($doc->createCDATASection($location[0])); 
    $b->appendChild($city); 

    $state = $doc->createElement("state"); 
    $state->appendChild($doc->createCDATASection($location[1])); 
    $b->appendChild($state); 

    $r->appendChild($b);  

endwhile; 

我不認爲這是我的標題中的空行問題，因爲我有一個完全相同的腳本，唯一不同的是從數據庫中提取的用戶數據。當我將查詢交換出來時，破損的腳本沒有任何問題。

這個錯誤讓我瘋狂。非常感謝您的幫助。

編輯：這裏是預期的輸出的一個示例我被要求爲

<source> 
    <publisher>mydomain.com</publisher> 
    <publisherurl>http://mydomain.com</publisherurl> 
    <job> 
     <company_name>ABC Company</company_name> 
     <date>3-4-2011 10:54</date> 
     <referencenumber>1234</referencenumber> 
     <url>http://www.mydomain.com/extension</url> 
     <description>Block of of content, likely ranging several thousand characters. HTML tags included, but should be sanitized by use of createCDATASection() method</description> 
     <city>Oakland</city> 
     <state>California</state> 
    </job> 
</source>
