php simple xpath question

Question

I have this div:

<div class="product-name">Product1</div>

I also have this div:

<div class="product-name gold">Product2</div>

How can I alter this xpath query to get whatever divs which contains product-name? Instead of getting an exact match.

/html/body//div[@class='product-name']

I googled it, but all I could find is how to use contains when searching for a value within a node, and not an attribute.

EDIT enter image description here

@Alex, why do you need to see any source other than what I have provided? — Or Weinberger

Valid XML should have only one root node. Wrap your divs with <html><body>..</body></html> and everything will be ok. — Alex Nikolaenkov

because there may be problem. Your XPath testing tool allows not valid XML documents :) While the one I'm referencing in my comment produces XML Error: System.Xml.XmlException: There are multiple root elements. Line 4, position 2. at System.Xml.XmlTextReaderImpl.Throw(Exception e) when the same document is supplied. — Alex Nikolaenkov

The classic XPath 1.0 answer for this existencial test on sequence is:

/html/body//div[
   contains(
      concat(' ',normalize-space(@class),' '),
      ' product-name '
   )
]

You can use contains():

/html/body//div[contains(@class, 'product-name')]

Update:

As @Alejandro points out in his comment, this would also match any class that contains product-name. See his answer for a XPath 1.0 solution.

If you use XPath 2.0, you could also do this:

/html/body//div[exists(index-of(tokenize(@class, "\s+"), "product-name"))]

Doesn't pick up the second div, also checked here emdin-here.ru/r/xpath_checker

@OrW: This solution is correct (as per your question). If it does not work for you, your question does not represent your problem.

Felix Kling Over a year ago

@OrW: It works for me. Are you passing the right document? If you are using the exact XPath above, the document must include html and body nodes. Or remove /html/body from the path and try again.

@OrW: You provided a not valid XML document. A XML document has always only one root node. Put both divs and a <root> element or in <html><body>....

@OrW: Your're welcome :) To be honest, I did the same mistake ;) :D

/html/body//div[contains(@class,'product-name')]

Attributes are also nodes, they are called attribute nodes.

For some reason, that still does not pick up the product-name gold

please verify that your code is correct. The //div part is correct and meets your requirements. Verify that not matching div is descendant of the /html/body. You can verify this XPath f.i. at xmlme.com/XpathTool.aspx
