XPath wildcards and contains() function usage
I have a problem using XPath and contains function. Imagine the XML example below:
<doc>
<Test>
<Name>1 Pre Histoy</Name>
<Type>Known</Type>
<Data>
<Name>Dinasor</Name>
<Name>Fish</Name>
</Data>
</Test>
<Test>
<Name>1 Post Histoy</Name>
<Type>Known</Type>
<Data>
<Name>Human</Name>
<Name>Dog</Name>
</Data>
</Test>
<Test>
<Name>1 Post Histoy</Name>
<Type>UNKNOWN</Type>
<Data>
<Name>Human</Name>
<Name>Dog</Name>
</Data>
</Test>
</doc>
So what I want to do is returning all <Name>
texts within <Data>
node, with following criteria:
doc//Test/Name
should contain "Pre" textdoc//Test/Type
should be "Known"
What I need is a query like this but so far I couldn't mana开发者_StackOverflowge it
/doc//Test[Name contains(.,'Pre') and Type='Known']/data//Name
Any help and tips will be appreciated.
Try this:
/doc/Test[contains(Name, "Pre") and Type="Known"]/Data/Name
Here is a working example implemented in Javascript to take advantage of StackOverflow's Runnable Code Snippets
function fu(path){
var output = "";
var results = document.evaluate(path, document, null, XPathResult.ANY_TYPE , null);
while(nextResult = results.iterateNext()){ output += nextResult.outerHTML + "\n"; }
return output;
}
document.body.innerText = fu('//doc/Test[contains(Name, "Pre") and Type="Known"]/Data/Name');
<doc>
<Test>
<Name>1 Pre Histoy</Name>
<Type>Known</Type>
<Data>
<Name>Dinasor</Name>
<Name>Fish</Name>
</Data>
</Test>
<Test>
<Name>1 Post Histoy</Name>
<Type>Known</Type>
<Data>
<Name>Human</Name>
<Name>Dog</Name>
</Data>
</Test>
<Test>
<Name>1 Post Histoy</Name>
<Type>UNKNOWN</Type>
<Data>
<Name>Human</Name>
<Name>Dog</Name>
</Data>
</Test>
</doc>
