php和xml解析錯誤：解析錯誤，意外T_OBJECT_OPERATOR

-2

我一直在從事涉及從XML文件讀取的PHP頁面。但是，我看到了此錯誤消息：解析錯誤：解析錯誤，第24行中出現意外的T_OBJECT_OPERATOR。但我不確定導致錯誤的原因。所以我想知道是否有人可以弄清楚我做錯了什麼。php和xml解析錯誤：解析錯誤，意外T_OBJECT_OPERATOR

<?php 
if (!isset($_GET["searchstr"])) 
    print "no Search String is provided! <br />"; 
else if (!isset($_GET["searchtype"]) || empty($_GET["searchtype"])) 
    print "No Search type is selected!<br />"; 


    else 
{ 
    $searchstr = $_GET["searchstr"]; 
    $searchtype = $_GET["searchtype"]; 

    $xmlDoc = new DOMDocument(); 
    @ $success = $xmlDoc->load("books.xml"); 
    if (!$success) 
     print "No XML book data on the server!"; 


else 
{ 
    $books = $xmlDoc->getElementsByTagName("book"); 
    $num = 0; 
    foreach ($books as $book) 

     $title = $book->getElementsByTagName("title")->item(0)->firstChild->nodevalue;   
     $isbn13 = $book->getElementsByTagName("ISBN13")->item(0)->firstchild->nodevalue; 
     $isbn10t = $book->getElementsByTagName("ISBN10"); 
     $isbn10 = ""; 
    if ($isbn10t->length > 0) 
     $isbn10 = $isbn10t->item(0)->firstchild->nodevalue; 

     $authors = $book->getElementsByTagName("author"); 
     $author = ""; 
     for ($j=0; $j<$authors->length; $j++) 
     { 

if ($j>0) 
      { 
       if ($j < $authors->length-1) $author .= ". "; 
       else $author .= " and "; 
      } 
      $author .= $author->item($j)->getElementsByTagName("firstname")->item(0)->firstchild->nodevalue;

     } 
     $desc = $book->getElementsByTagName("descritpion"); 
     $description = ""; 
     if ($desc->length > 0) 
      $descreption = $desc->item(0)->firstchild->nodevalue; 

     if (empty($searchstr) 
     || searchtype == "title" && eregi($searchstr,$title) 
     || $searchtype == "isbn" && (eregi($searchstr, $author) 
     || $searchtype == "keyword" && (eregi($searchstr, $title) || eregi($searchstr, $description) 

{ 
      $num++ 
      print "{$num}. Title: <a href=\"select.php?isbn={$isb13}\">{$title}</a><br />"; 
      print "Author: {$author}<br />" 
      print "ISBN-13. "; 
      print $books->getElementsByTagName("ISBN13")->item(0)->firstchild->nodevalue."<br />"; 
      $isbn10 = $book->getElementsByTagName("ISBN10"); 
      if ($isbn10->length > 0) 
      { 
       print " ISBN-10: " . $isbn10->item(0)->firstchild-nodevalue. "<br />"; 
      } 
      print "Price: $"; 
      print $book->getElementsByTagName("price")->item(0)->firstchild->nodevalue. "<br />";

     } 
     if ($num == 0) 
      print "no book is found!"; 
    } 


} 
}

這裏是我使用

<book id="1"> 
    <title>Beginning ASP.NET 4 in C# 2010</title> 
    <authors> 
     <author> 
     <lastname>MacDonald</lastname>

    <price>49.99</price> 
    <description>This book discusses ASP.NET programming in C# with Visual Studio 2010.</description> 
    </book>

這裏是從搜索頁面的代碼，PHP頁面之前的頁面的XML代碼的一個例子。

該錯誤消息通常包含一個行號。看那裏的問題。我們無法分辨，因爲您遺漏了這個珍聞。反正本地化也是如此。 – mario 2013-04-23 21:44:14

您可能還想發佈一個給您提供問題的XML示例。 – pilsetnieks 2013-04-23 21:50:52

我得到一個_「PHP解析錯誤：語法錯誤，意外的'{'」_你的代碼43行（未關閉，如果語句）。看看方便的線路號碼是多少？ – Wrikken 2013-04-23 21:58:43

您在這幾個代碼語法錯誤：

foreach ($books as $book) // this is invalid given the lines below it and the lines at 
// the end of the page. You forgot to open this: 

foreach ($books as $book) { //this is what it should be. 

$author .= $author->item($j)->getElementsByTagName("firstname")->item(0)->firstchild->nodevalue; 
$author .= " " . $authors->item($j)->getElementsByTagName("lastname")-item(0)->firstchild->nodevalue; 

$isbn10 = $isbn10t->item(0)->firstchild->nodevalue; 

$descreption = $desc->item(0)->firstchild->nodevalue; 

print $books->getElementsByTagName("ISBN13")->item(0)->firstchild->nodevalue."<br />"; 
//  ^not to mention, you need to delete this S ^ and ^both need to be upper-case 

// The above lines(and pretty much every single instance in which you use those two 
// methods) are using an incorrect property. nodevalue should be nodeValue, 
// firstchild should be firstChild. The capital C/V makes all the difference. 

$num++ 
    //^no semi-colon 

print "Author: {$author}<br />" 
          //^no semi-colon 

print "<br />" 
     // ^again, no semi-colon 

// the below.. 

$author .= $author->item($j)->getElementsByTagName("firstname")->item(0)->firstchild->nodevalue; 

//should be this: 

$author .= $authors->item($j)->getElementsByTagName("firstname")->item(0)->firstchild->nodevalue; 
//    ^notice the s here 

$author .= " " . $authors->item($j)->getElementsByTagName("lastname")-item(0)->firstchild->nodevalue; 
//                 ^forgot a key character, the >

此：

if (empty($searchstr) 
    || searchtype == "title" && eregi($searchstr,$title) 
    || $searchtype == "isbn" && (eregi($searchstr, $author) 
    || $searchtype == "keyword" && (eregi($searchstr, $title) || eregi($searchstr, $description)

應該是類似於..（記住關閉() S）（這是主要是猜測，因爲我不知道這個代碼的目的）：

if (empty($searchstr) 
    || searchtype == "title" && eregi($searchstr,$title) 
// ^forgot the $ here, unless you have a constant called 'searchtype' 
    || $searchtype == "isbn" && (eregi($searchstr, $author)) 
    || $searchtype == "keyword" && (eregi($searchstr, $title) || eregi($searchstr, $description)))

最後，就在這裏：

print " ISBN-10: " . $isbn10->item(0)->firstchild-nodevalue . "<br />"; 
// The C and V need to be upper case and  ^you forgot the >

與所有固定這些錯誤，代碼爲我工作得很好。

你也忘了定義一個你稍後使用的變量，在另一個塊中。你會得到一個通知告訴你這一點，但它不會阻止你的代碼工作，所以我沒有包含它。 – Daedalus 2013-04-23 23:43:07

我不知道爲什麼，但似乎儘管你做了這些改變，但它仍然告訴我，我有一個解析錯誤：解析錯誤，第24行出現意外的T_OBJECT_OPERATOR。 – herkles 2013-04-24 00:27:26

@herkles刪除第24行和周圍的行，重新打字。這可能是一個隱藏的角色從您複製的地方複製而來。 – Daedalus 2013-04-24 00:42:18
