Question

Hoi,

for example, i have a xml file :

<bookstore>

<book category="COOKING">
  <title lang="en">Everyday Italian</title>
  <author>Giada De Laurentiis</author>
  <year>2005</year>
  <price>30.00</price>
</book>

<book category="WEB">
  <title lang="en">XQuery Kick Start</title>
  <author>James McGovern</author>
  <author>Per Bothner</author>
  <author>Kurt Cagle</author>
  <author>James Linn</author>
  <author>Vaidyanathan Nagarajan</author>
  <year>2003</year>
  <price>49.99</price>
</book>

</bookstore>

And I want all the titles and prices

I could write this code

<php
$res = $xpath->query('/bookstore/book/title');
foreach ($res as $item) {
  echo "{$item->nodeValue}";
}  
$res = $xpath->query('/bookstore/book/price');
foreach ($res as $item) {
  echo "{$item->nodeValue}";
}  
?>

But this looks very ugly,
Is there another possibility so that I can combine those 2 blocks of code?

something like this?

<php
$res = $xpath->query('/bookstore/book');
foreach ($res as $item) {
  echo "{$item->title} <br/> {$item->price}";
}  
?>

Kind regards

You could adjust your XPATH with concatenate to read ‘/bookstore/book/title | /bookstore/book/price’
This would give you a node list as such:

<title lang="en">Everyday Italian</title>
<price>30.00</price>
<title lang="en">XQuery Kick Start</title>
<price>49.99</price>
...
...

Then just pull values 1 and 2 in each foreach loop cycle for what you like.

Hope this helps!
