使用PHP使用ID标记提取XML

I have a relatively complex XML file which looks like the following but with many more 'Match' tags (something like 150 Entities, each containing 100+ 'Match' IDs):

<Query results>    
  <Entity>
   <Name>Bill</Name>
   <Watchlist>
      <Match ID=1>
          <Info></Info>
      </Match>
      <Match ID=2>
          <Info></Info>
      </Match>
      ...
      <Match ID=99>
          <Info></Info>
      </Match>
  </Entity>
</Query results>

I have written the following PHP to extract 'Info' from the 'Match' tag for every 'Entity' but it only extracts 'Info' the first of the 'Match' tags i.e. ID=1:

xml=simplexml_load_file($file) or die("Error: Cannot create object");
foreach($xml->children() as $i) { 
    echo "Name:" . $i->Name . " <br /> ";
    echo "Info:" . $i->Watchlist->Match . " <br /> ";
}

What I want to do is extract the 'Info' from all the 'Match' tags for each 'Entity' so I can put them into a HTML table that will show the following:

Name   Match
Bill   ID=1>Info
Bill   ID=2>Info
Bill   ID=3>Info
...
Bill   ID=99>Info

Any help to extract all the ID's would be much appreciated.

** UPDATE **

I tried the following code:

$xml=simplexml_load_file($fileinfo) or die("Error: Cannot create object");
foreach($xml->children() as $i) { 
    echo "Name:" . $i->Name . " <br /> ";
    foreach($i->WatchList->Match as $match) {
        echo $i->WatchList->Match->Info;
    }
 }

This gave some interesting results, it gave me the right number of ID records (154) but it repeated the text in ID=1 'Info' tag i.e. if ID=1 'Info' said "HELLO WORLD!" it repeated this exactly 154 times.

Looking at the output like ID=99>Info, It appears that what you're seeing is actually XML itself mis-rendered as HTML by your browser, as in <Match ID=99>Info. If you look at the browser's page source, you'll probably find much of your information there, but not organized as intended.

Let's backup a little and iterate from the root node. Instead of using children(), iterate on the node names themselves. That is, after all, what makes SimpleXML easier to use than other XML APIs in PHP.

$xml=simplexml_load_file($fileinfo) or die("Error: Cannot create object"); // Loop over the Entity nodes: foreach ($xml->Entity as $e) { // Write out the name, and all Match nodes in a loop: foreach ($e->Watchlist->Match as $m) { // The Name will be repeated for each Match since it is from // a level higher: echo "Name: " . (string)$e->Name . "<br/>"; // The ID attribute with an array access to $m echo "ID: " . (string)$m['ID'] . "<br/>"; // The <Info> node from $m echo "Info: " . (string)$m->Info . "<br/>"; } }

Internally to the loop, you may reformat these to get them in the output you want (removing <br/> for example, or moving the Name node to print before the inner loop).

Here's a demonstration: http://codepad.viper-7.com/gCoc9g

And another one modified to use your real XML. Note that the node names are case-sensitive. So <Watchlist> is not the same as <WatchList>!
