Not present than skip lines

[beh_gras_beh]

Dear people,

Is it possible for InDesign to skip rules in the script if something is not present?

Il try to illustrate what I mean:

//Map the XML tags to the defined styles.
var myDocument = app.documents.item(0);
//Part 1.
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_1"),
myDocument.paragraphStyles.item("myparagraphStyle_1"));
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_2"),
myDocument.paragraphStyles.item("myparagraphStyle_2"));
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_3"),
myDocument.paragraphStyles.item("myparagraphStyle_3"));
//Part 2.
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_a1"),
myDocument.paragraphStyles.item("myparagraphStyle_1"));
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_a2"),
myDocument.paragraphStyles.item("myparagraphStyle_2"));
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_a3"),
myDocument.paragraphStyles.item("myparagraphStyle_3"));
//Map the XML tags to the defined styles.
myDocument.mapXMLTagsToStyles();

 

Part 2 is not present in the InDesign document so the script returns with an error that he cannot find Part 2.

So is it possible to run the script like:

If part 1 and 2 is present go on

If part 2 is NOT present ignore and go on.

Already thanks for the help!

Greetings from Holland!

Hi,

Do you mean something like this (not tested):

//Map the XML tags to the defined styles.
var myDocument = app.documents.item(0);
 
//Part 1.
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_1"),
myDocument.paragraphStyles.item("myparagraphStyle_1"));
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_2"),
myDocument.paragraphStyles.item("myparagraphStyle_2"));
myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_3"),
myDocument.paragraphStyles.item("myparagraphStyle_3"));
 
//Part 2.
if(myDocument.xmlTags.item("TAGNAME_a1") != null)
{
     myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_a1"),
     myDocument.paragraphStyles.item("myparagraphStyle_1"));
     myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_a2"),
     myDocument.paragraphStyles.item("myparagraphStyle_2"));
     myDocument.xmlImportMaps.add(myDocument.xmlTags.item("TAGNAME_a3"),
     myDocument.paragraphStyles.item("myparagraphStyle_3"));
}
 
//Map the XML tags to the defined styles.
myDocument.mapXMLTagsToStyles();
