DOM doc - 简单的查找元素

大家好 -

我是PHP新手。我找到了FAQTS和php手册。我正在尝试这个

序列，但得到''没有找到zip字符串：''... PHP版本4.4.0


$ doc = new DomDocument ;

$ res = $ doc-> loadHTMLFile（&.;。/ aBasicSearchResult.html"）;

if（$ res == true）

{

$ zip = $ doc-> getElementById（''zipRaw_id''） - > value;

if（0！= $ zip）{

$ sql =''SELECT stuff ...''。 $ zip;


$ selected = mysql_select_db（$ database，$ x_testC）;

if（！$ selected）{

$ res =''未连接：''。 mysql_error（）;

} else {

$ Result1 = mysql_query（$ sql，$ x_testC）;

if（！$ Result1）{

$ res =''无查询：''。 mysql_error（）;

} else {

$ res = mysql_num_rows（$ Result1）;

}

}

}否则{

$ res ="找不到拉链字符串：" 。 $ zip;

}

}其他{

$ res =" loadHTMLFile（）返回false&quot ;;

}


-----
Javascript中的
，这可以在doc


setTextContent（getElementById_s）中运行（''divZipCheckRes''），

getElementById_s（''zipRaw_id''）。value）;


getElementById_s（）是浏览器兼容性的封面功能..


-----

我刚试过这些变化


$ elem = $ doc- > getElementById（''zipRaw_id''）;

// $ zip = $ elem-> getAttribute（''value''）;

$ zip = $ elem-> innerText;


仍然没有什么

任何线索？提前谢谢

Hi All-
I am new to PHP. I found FAQTS and the php manual. I am trying this
sequence, but getting ''no zip string found:''... PHP Version 4.4.0

$doc = new DomDocument;
$res = $doc->loadHTMLFile("./aBasicSearchResult.html");
if ( $res == true )
{
$zip = $doc->getElementById(''zipRaw_id'')->value;
if ( 0 != $zip ) {
$sql = ''SELECT stuff...'' . $zip;

$selected = mysql_select_db($database, $x_testC) ;
if ( !$selected ) {
$res = ''Not connected : '' . mysql_error();
} else {
$Result1 = mysql_query($sql, $x_testC) ;
if ( !$Result1 ) {
$res = ''No query : '' . mysql_error();
} else {
$res = mysql_num_rows($Result1);
}
}
} else {
$res = "no zip string found: " . $zip;
}
} else {
$res = "loadHTMLFile() returned false";
}

-----
in Javascript, this works in the doc

setTextContent( getElementById_s(''divZipCheckRes''),
getElementById_s(''zipRaw_id'').value );

getElementById_s() is a cover func for browser compatability..

-----
I just tried these variations

$elem = $doc->getElementById(''zipRaw_id'');
//$zip = $elem->getAttribute( ''value'' );
$zip = $elem->innerText;

still nothing
any clues?? thanks in advance
