<body>
<script type="text/javascript" src="NotThisFile1.js"></script>
<script type="text/javascript" src开发者_开发问答="NotThisFile2.js"></script>
<script type="text/javascript" src="NotThisFile3.js"></script>
<script type="text/javascript" src="NotThisFile4.js"></script>
</body>
</html>
Thanks, Yosef
Use:
/*/head/script/@src
or
string(/*/head/script/@src)
The first XPath expression selects all src attributes of all script elements that are childtren of all head elements that are children of the top element in the XML document.
The second XPath expression evaluates to the string value of the first of the attributes, selected by the first XPath expression. This would be most convenient if your XPath engine's API provides support for evaluting XPath expression that do not select nodes. If this is not the case you have to use the first XPath expression, then use the appropriate method/property of the API that returns the string value of the selected attribute node.
