            38-year-old left-hander Mark Mulder will not be attempting another comeback this tear, according to Jerry Crasnick of ESPN and Baseball America. Mulder tried to return from a lengthy hiatus last year, but a comeback bid ended with a spring training injury in Angels camp last year. "I just couldn't get where I needed to be," Mulder said. Mulder went 103-60 with a 4.18 ERA in nine years in the majors. He hasn't pitched in an MLB game since 2008.

python代码：

 import xml.dom.minidom as minidom
 document = minidom.parse("cgi-bin/news.xml")
     page = document.childNodes[0]

     print "<html>"
     print "<head><title>NEW News Articles List</title></head>"
     print "<body>"
     print "<h2>Welcome to New News Inc.!<br> You are currently a GUEST here.</h2>"
     print """\
     <form method="GET" >
         <input type="submit" value="Submit" name="loginPageCall" >
     </form>
     """

     for child in page.childNodes:
         if child.nodeType == minidom.Node.TEXT_NODE:
             sys.stdout.write(child.data)
         elif child.nodeType == minidom.Node.ELEMENT_NODE:
             if child.nodeName == "TITLE":
                 sys.stdout.write('<a href="%s">%s</a>' % (child.getAttribute("url"), child.childNodes[0].data))

我想知道你为什么在所有代码中都有额外的标签。

 import xml.dom.minidom as minidom
 document = minidom.parse("cgi-bin/news.xml")
 page = document.childNodes[0]

 print "<html>"
 print "<head><title>NEW News Articles List</title></head>"
 print "<body>"
 print "<h2>Welcome to New News Inc.!<br> You are currently a GUEST here.</h2>"
 print """\
     <form method="GET" >
     <input type="submit" value="Submit" name="loginPageCall" >
     </form>
     """

 for child in page.childNodes:
     if child.nodeType == minidom.Node.TEXT_NODE:
         sys.stdout.write(child.data)
     elif child.nodeType == minidom.Node.ELEMENT_NODE:
         if child.nodeName == "TITLE":
             sys.stdout.write('<a href="%s">%s</a>' % (child.getAttribute("url"), child.childNodes[0].data))

我甚至没有读过您的代码，我相信如果逻辑错误，这至少会给您一些错误。

在这种情况下缩进代码会有所帮助
