How to get single value out of XML data

Hi,

I need to get a specific value out of this XML:

<summary-data>
<summary currency-code="AUD" name="enquiry-amount" type="amount">0</summary>
<summary name="age-of-file" type="months">236</summary>
<summary name="age-of-subject" type="years">38</summary>
<summary name="time-at-address" type="months">10</summary>
<summary name="time-at-employer" type="months">22</summary>
<summary name="defaults" type="count">9</summary>
<summary currency-code="AUD" name="defaults-value" type="amount">84683</summary>
<summary name="defaults-paid" type="count">0</summary>
<summary name="defaults-12" type="count">9</summary>
<summary name="defaults-12-paid" type="count">0</summary>
<summary name="defaults-12-unpaid" type="count">9</summary>
<summary name="defaults-24-paid" type="count">0</summary>
<summary name="defaults-24-unpaid" type="count">9</summary>
<summary name="defaults-36-paid" type="count">0</summary>
<summary name="defaults-36-unpaid" type="count">9</summary>
<summary name="time-since-last-default" type="months">1</summary>
<summary name="total-enquiries" type="count">24</summary>
<summary name="enquiries-1" type="count">0</summary>
<summary name="enquiries-3" type="count">0</summary>
<summary name="enquiries-6" type="count">0</summary>
<summary name="enquiries-12" type="count">7</summary>
<summary name="time-since-last-enquiry" type="months">9</summary>
<summary name="telco-and-utility-defaults" type="count">3</summary>
<summary name="telco-and-utility-defaults-12" type="count">3</summary>
<summary name="telco-and-utility-enquiries" type="count">0</summary>
<summary name="telco-and-utility-enquiries-6" type="count">0</summary>
<summary name="telco-and-utility-enquiries-12" type="count">0</summary>
<summary name="directorships" type="count">0</summary>
<summary name="judgements" type="count">1</summary>
<summary name="bankruptcies" type="count">0</summary>
<summary name="writs-and-summons" type="count">0</summary>
<summary name="external-administration-director" type="count">0</summary>
</summary-data>

Open in new window

In particular this one
<summary name="defaults" type="count">9</summary>
I wish to get the value of 9 out.

Could someone possibly show me how to do this using XPATH or simpleXML in PHP?

your help is much appreciated!
