jquery - php および xml 解析エラー: 解析エラー、予期しない T_OBJECT_OPERATOR

Question

XMLファイルからの読み取りを含むPHPページに取り組んでいます。しかし、次のエラーメッセージが表示されます: 解析エラー: 解析エラー、24 行目の予期しない T_OBJECT_OPERATOR。だから、誰かが私が間違っていることを理解できるかどうか疑問に思っています。

<?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;
            $author .= " " . $authors->item($j)->getElementsByTagName("lastname")-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 $book->getElementsByTagName("price")->item(0)->firstchild->nodevalue. "<br />";
            print "<br />"
        }
        if ($num == 0)
            print "no book is found!";  
    }


}
}

?>

これは私が使用しているXMLコードの例です

<book id="1"> 
    <title>Beginning ASP.NET 4 in C# 2010</title> 
    <authors> 
      <author> 
        <lastname>MacDonald</lastname> 
        <firstname>Matthew</firstname> 
      </author> 
    </authors> 
    <ISBNs> 
      <ISBN13>9781430226086</ISBN13> 
      <ISBN10>1430226080</ISBN10> 
    </ISBNs> 
    <publisher>Apress</publisher> 
    <publishdate>2010-05</publishdate> 
    <pages>981</pages> 
    <price>49.99</price> 
    <description>This book discusses ASP.NET programming in C# with Visual Studio 2010.</description> 
  </book>

このコードにはいくつかの構文エラーがあります。

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 >

これ：

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

..に似たものでなければなり()ません（sを閉じることを忘れないでください）（このコードの目的がわからないため、これはほとんど推測です）：

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)))

そして最後に、ここに：

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

これらのエラーをすべて修正すると、コードは正常に機能します。
