I want to extract from a web page information with xpath, but I'm getting the wrong information. In this code below I want to get `100` :

```
<div class="pricing">
 <p class="pricePerUnit">
  <p class="pricePerMeasure">
  £0.64
  <abbr title="per">/</abbr>
  100

```

I want to only get `100`, I tried this but it returns `£0.64 100`. But, I just want to retrieve the `100` : 

```
`prices_mesure3 = `response.xpath('//p[@class="pricePerMeasure"]/text()').extract()`

```

Any help please ?
