I am currently working with the following pseudo code block to fix a regex

  • 0

I am currently working with the following pseudo code block to fix a regex problem I am running into. currently I am using regex to find/remove various menu items based by id, however, it is only working for children, not the parent records. so in this example I am trying to remove id53 and if you run the pseudo code you will see it breaks the structure of the tree b/c it does not remove the entire <li></li> block.

anyone have any ideas on how to adjust the regex test pattern we are working with? I really appreciate your help and hope you have a great week.

    Writing a regex solution would need a recursive regex, and I don’t know whether CFML supports that. As I commented, XML DOM manipulation is the way to go. It would look something like this (untested as I have no access to a ColdFusion server.

    <cfsavecontent variable="pseudo">
<ul id="nav-main-links">
  <li class="standby" id="id61"><a href="/?event=User.Home.dspHome" target="_self" title="Home"> Home<font class="menuItemType">(CB)</font></a>
  <li class="standby" id="id53"><a href="/contactus.cfm" target="_self" title="Contacts"> Contacts<font class="menuItemType">(L)</font></a>
  <ul class="sub-nav-main-links nestingLevel1">
    <li class="standby" id="id54"><a href="http://test/index.cfm" target="_self" title="Ven"> Ven<font class="menuItemType">(X)</font></a></li>
    <li class="standby" id="id55"><a href="http://test/spEvents.cfm" target="_self" title="SponsorShip"> SponsorShip<font class="menuItemType">(L)</font></a></li>
  </ul>
  </li>
</ul>
</cfsavecontent>

<cfscript>

  myDisplay=structnew();
  myDisplay.IdsToRemove = "53";
  idVal = 'id' & myDisplay.IdsToRemove;

  xmlTree = xmlParse(pseudo);
  liList = xmlSearch(xmlTree, '//li[@id="' & idVal & '"]');
  arrayDeleteAt(liList, 0);

  myDisplay.pseudo = toString(xmlTree);

</cfscript>
