Check if XML tag exists?
Subject: Check if XML tag exists? From: David C Petite <david@xxxxxxxxxxxxx> Date: Wed, 16 Aug 2000 17:24:37 -0500 |
Hey folks, First timer on the list here... i could have swore I had seen this in the XLS FAQ before it was re-organized on its new domain, but after a half hour of hunting, I cannot find the answer. Is there a way I can check if a TAG in the XML data exists or not, even though the possibly existing TAG will not have any value? Background is... in this instance everything would be hidden. <RESTRICTED_FIELD_LIST> <HIDE_OFFICE_ALL /> <HIDE_HOME_ALL /> </RESTRICTED_FIELD_LIST> But in this instance ALL the Office info would be hidden while only the Home Address info would be hidden. <RESTRICTED_FIELD_LIST> <HIDE_OFFICE_ALL /> <HIDE_HOME_ADDRESS /> </RESTRICTED_FIELD_LIST> The HIDE_HOME_ALL is no longer in the data. Can I check to see if a TAG exists or not? ___________________________________________ david c petite Lead Site Builder david@xxxxxxxxxxxxx http://www.standpipe.com ------------------------------------------- " 'Ace, watch your head!' hissed Wanda urgently, yet somehow provocatively, through red, full, sensuous lips, but he couldn't you know, since nobody can actually watch more than part of his nose or a little cheek or lips if he really tries, but he appreciated her warning." -Dark & Stormy Contest Winner ------------------------------------------- XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
