我可以使用xslt显示下拉菜单

时间：2022-01-14 07:59:34

Hi I have this done using xml, php and css for styling.

嗨，我已经完成了使用xml，php和CSS进行样式设置。

But is it possible to have information in an xml file. And use xslt to display the information in a table. I have a PHP and javascript file as well.

但是有可能在xml文件中包含信息。并使用xslt在表中显示信息。我也有PHP和javascript文件。

XML file

XML文件

<?xml version="1.0"?>

<TT>

<BUS>
<NUMBER>120</NUMBER>    
<LEAVING>Howth</LEAVING>
<DESTINATION>Dublin Airport</DESTINATION>
<TIME>06:00, 07:00, 08:10, 9:10, 10:00,
11:25, 12:00, 13:00, 14:00, 15:20, 16:00, 17:00, 18:00</TIME>
</BUS>
</TT>

PHP

PHP

<?php

$id=$_GET['q'];
$dom=new DOMDocument;
$dom->load( 'routes.xml' );

$col=$dom->getElementsByTagName('NUMBER');

if( $col ){
foreach( $col as $node ){


if( $node->nodeType==XML_ELEMENT_NODE && $node->nodeValue==$id ) {
$parent=$node->parentNode;
}
}


$html=array();
$html[]='
</br>

<table border="2">

 <tr>
 <th>NUMBER</th>
 <th>LEAVING</th>
 <th>DESTINATION</th>
 <th>TIME</th>
 </tr>
 <tr>';

 foreach( $parent->childNodes as $node ){
 if( $node->nodeType==XML_ELEMENT_NODE ) $html[]='<td>'.$node-           >nodeValue.'</td>';
 }

 $html[]='</tr><tr background-color: #f2f2f2></table>';
 echo implode( PHP_EOL, $html );
 }  


 ?>

JavaScript

JavaScript的

function showBus(str){
if (str==""){
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else {  // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}

xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}

xmlhttp.open("GET","getbus.php?q="+str,true);
xmlhttp.send();
}

HTML

HTML

<body>
<form>
<h3>Select your bus route:</h3>
<select name="NUMBER" onchange="showBus(this.value)">
<option value="">Select a Bus:</option>
<option value="15">15</option>
<option value="22">22</option>
<option value="37">37</option>
<option value="44">44</option>
<option value="120">120</option>
</select>
<div id="txtHint"><b>Bus info will be listed here...</b></div>

</form>
</body>
</html>

I want to display the xml data with each BUS Number in the menu, when you click on the number the information such as destination time is displayed in a table, but i want it using xslt not html.

我想在菜单中显示每个BUS编号的xml数据，当你点击数字时，目的地时间等信息会显示在一个表格中，但我希望它使用xslt而不是html。

Indeed it can all be done using XSLT rather than PHP, it's a bit more involved but it can be done. I still have the original XSL file you posted with the original question and have modified it slightly here.

事实上，它可以使用XSLT而不是PHP来完成，它可以更多地参与其中，但它可以完成。我仍然使用原始问题发布了原始XSL文件，并在此稍作修改。

To allow user to add a route

You need a form, you need to be able to identify the user, you need to have a location to store the generated xml files and probably a whole heap of other things too. So, very quickly:

你需要一个表单，你需要能够识别用户，你需要有一个位置来存储生成的xml文件，也可能是一大堆其他东西。所以，很快：

A CSS stylesheet is required at relative url buses.css. I used this content, but it is not important. ...

相对url的bus.css需要一个CSS样式表。我使用了这个内容，但并不重要。 ...

table {
  border-collapse: collapse;
}

td,
th {
  border: 1px solid #999;
  padding: 0.5rem;
  text-align: left;
}

td {
  background: hsl(150, 50%, 50%);
}

And the final resource required is the Saxon/CE library. The resource should be placed at relative url js/Saxonce/Saxonce.nocache.js.

所需的最终资源是Saxon / CE库。资源应放在相对url js / Saxonce / Saxonce.nocache.js中。

The outcome

This is the perfect solution. The body of the table dynamically changes to match the user selection of bus. There are no call-backs. All switching is done on the client side, so performance scales very well. Data, html structure, visual styling, and business rules are neatly segregated into separate files. A user can write their own bus routes and save it in the xml file. The whole solution is small and simple.

这是完美的解决方案。表的主体动态地改变以匹配用户对总线的选择。没有回电。所有切换都在客户端完成，因此性能可以很好地扩展。数据，html结构，视觉样式和业务规则被巧妙地分隔成单独的文件。用户可以编写自己的总线路由并将其保存在xml文件中。整个解决方案小而简单。

A CSS stylesheet is required at relative url buses.css. I used this content, but it is not important. ...

相对url的bus.css需要一个CSS样式表。我使用了这个内容，但并不重要。 ...

table {
  border-collapse: collapse;
}

td,
th {
  border: 1px solid #999;
  padding: 0.5rem;
  text-align: left;
}

td {
  background: hsl(150, 50%, 50%);
}

And the final resource required is the Saxon/CE library. The resource should be placed at relative url js/Saxonce/Saxonce.nocache.js.

所需的最终资源是Saxon / CE库。资源应放在相对url js / Saxonce / Saxonce.nocache.js中。

The outcome

This is the perfect solution. The body of the table dynamically changes to match the user selection of bus. There are no call-backs. All switching is done on the client side, so performance scales very well. Data, html structure, visual styling, and business rules are neatly segregated into separate files. A user can write their own bus routes and save it in the xml file. The whole solution is small and simple.

这是完美的解决方案。表的主体动态地改变以匹配用户对总线的选择。没有回电。所有切换都在客户端完成，因此性能可以很好地扩展。数据，html结构，视觉样式和业务规则被巧妙地分隔成单独的文件。用户可以编写自己的总线路由并将其保存在xml文件中。整个解决方案小而简单。
