Aide de Scilab >> Traitement XML > xmlAsNumber


Convert the result of a XPath query into a row of numbers


nums = xmlAsNumber(xp)



xp, a XML mlist typed XMLSet or XMLList


nums, a single row of doubles


The result of a XPath query or the children of a node can be a set of XMLElements which contains numbers, so the aim of this function is to convert the contents of each nodes into a double.


doc = xmlReadStr("<root><a>12</a><a>13</a><a>1.2345678</a><a>45e3</a><a>.23E-2</a></root>");

// Retrieve the content of the nodes with name equal to "a"
xp = xmlXPath(doc, "//a/text()");

// convert the result into doubles
data = xmlAsNumber(xp)
