How to insert XML fragments stored in an attribute into XML document using XMLUpdater

Hi @dms2​ , the reason for the error is that the value of distr_formats is NOT a single XML fragment, it's just a concatenated string of two <gmd:distributionFormat> fragments.

A possible workaround is to transform the value to an XQuery sequence - comma-separated elements quoted by round brackets - before entering it to the XMLUpdater.

(
<gmd:distributionFormat><gmd:MD_Format><gmd:name><gco:CharacterString>DWG</gco:CharacterString></gmd:name><gmd:version><gco:CharacterString>r2013</gco:CharacterString></gmd:version><gmd:fileDecompressionTechnique><gco:CharacterString>ZIP</gco:CharacterString></gmd:fileDecompressionTechnique></gmd:MD_Format>
</gmd:distributionFormat>
,
<gmd:distributionFormat><gmd:MD_Format><gmd:name><gco:CharacterString>SHP</gco:CharacterString></gmd:name><gmd:version><gco:CharacterString>-</gco:CharacterString></gmd:version><gmd:fileDecompressionTechnique><gco:CharacterString>ZIP</gco:CharacterString></gmd:fileDecompressionTechnique></gmd:MD_Format>
</gmd:distributionFormat>
)

How to? For example,

StringReplacer

• Attributes: distr_formats
• Mode: Replace Regular Expression
• Case Sensitive: No
• Text To Replace: (</gmd:distributionFormat>)\s*(<gmd:distributionFormat>)
• Replacement Text: \1,\2

StringConcatenator

•  Expression Results: Overwrite Existing Attributes
• Attributes To Overwrite: distr_formats
• Concatenation: (@CurrentAttribute())

Thank you so much @Takashi Iijima​ .

Both options are good for me but the Xquery expression saves me from adding extra transformers to the flow.

Learning XQuery still is a pending topic I've had for years. I'd like to dig into it some day. I must say though that it's you who I must thank for the little I know of it.
