Question

I am trying to parse a HTML document with help of DOM Xpath

I have several input tags in the HTML such as

<form id="someid" action="login.jsf">
   <input type="hidden" id="someid" name="somename" value="somevalue">
   <input type="text" id="someid" name="somename" value="somevalue">
</form>

I have following code to reach the all the input tags inside form.

$inputFields = $xpath->query("//form[contains(@action,'login.jsf')]/input/@*");

It returns me all the input nodes with all the attributes but I only need name and value attributes otherwise I will have to run loop around all the attributes and discard all others except name and value. Basically I want to “select all the input nodes only with name and value attributes.”

I need to create an post array based on name and value attribute values.

I have tried following

 $inputFields = $xpath->query("//form[contains(@action,'login.jsf')]/input/[@name | @value]");

But this doesn’t work.

You can use the name function to get a name of an attribute:

//form[contains(@action,'login.jsf')]/input/@*[name()='name' or name()='value']
