How to use the AND operater in javascript within an XSLT document -

-

i've got script in xsl document , it's throwing error when try , use javascript , operator (&&). 

if (input1=="" && input2==""){     alert ("test"); }

the error comes is: xml parsing error: not well-formed , points && operator.

how can around this?

if writing xslt writing xml document , xslt code needs well-formed xml. either escape ampersands && or use cdata section

<script><![cdata[ if (input1 == "" && input2 == "") {    alert("test");  } ]]></script>

if trying create html or svg script elements in xslt of course third option make use of external scripts e.g. put javascript code .js file , reference <script src="file.js"></script>, way don't have take efforts escape script code according xml rules.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor
